JP 2019-087160 A

Although it is effective to introduce multiple systems into the same store to meet the needs of shoppers, introducing and operating multiple systems can lead to various problems (e.g., operability, costs, etc.).

The present invention was made in light of these circumstances, and aims to provide technology to resolve various problems that arise when multiple systems are in operation.

One aspect of the present invention for solving the above-mentioned problems is a product sales data processing device that is characterized by having a first processing mode in which products registered on a portable registration terminal are settled, a second processing mode in which a customer registers and settles products on the product sales data processing device himself, and a selection means for selecting either the first processing mode or the second processing mode.

Figure 1 is a conceptual diagram of a network to explain a sales system 1. The sales system 1 shown in Figure 1 includes a store controller 10, a cloud server 20, a POS terminal 40, a transaction status management device 50 (e.g., a personal computer, etc.), and a mobile terminal 60 (e.g., a smartphone, etc.). The sales system 1 can be introduced in various stores (supermarkets, convenience stores, drug stores, home centers, electronics retailers, other specialty stores, etc.).

(Service A, Service B)
The sales system 1 provides two types of self-services. The first self-service is a self-service in which the customer uses the mobile terminal 60 to register products and uses the POS terminal 40 to settle the payment (hereinafter, this may be referred to as service A). In other words, service A is a self-service in which the customer himself registers products and settles the payment, but uses the mobile terminal 60 for product registration and the POS terminal 40 for settlement. The second self-service is a self-service in which the customer uses the POS terminal 40 to register products and settle the payment (hereinafter, this may be referred to as service B). In other words, service B is a self-service in which the customer himself registers products and settles the payment, but uses the POS terminal 40 for both product registration and settlement.

(Service A Customer (Customer A), Service B Customer (Customer B))
In the following description, a customer who uses service A may be referred to as a "service A customer" or simply as an "A customer." A customer who uses service B may be referred to as a "service B customer" or simply as an "B customer."

The store controller 10, POS terminal 40, and transaction status management device 50 are installed in a store and are connected to each other so as to be able to communicate with each other via a LAN 19 (which may be wired or wireless). The store controller 10 is capable of communicating with a cloud server 20. Note that the number of devices in FIG. 1 is merely an example. For example, while two POS terminals 40 are illustrated in FIG. 1, the number of POS terminals 40 in one store may be one or three or more. Also, while one transaction status management device 50 is illustrated in FIG. 1, the number of transaction status management devices 50 in one store may be two or more.

The store controller 10 receives, for example, product files (product master data) and sale files from an external device (e.g., a headquarters server (not shown)), supplies them to the POS terminal 40, and receives transaction information from the POS terminal 40 and transmits it to the external device.

A product file is, for example, a file that stores product names, sales prices, etc. in association with product identification information (product codes) that identifies individual products. A sale file is, for example, a file that stores sale periods (start and end dates and times) and sale details (conditions for discounts and reductions, details of discounts and reductions) in association with product identification information.

The cloud server 20 is a server that provides various services. For example, the cloud server 20 provides service A (a service in which products are registered using a mobile terminal 60). For example, the cloud server 20 manages (stores) various information related to service A (for example, transaction information (cart information), etc.).

The cloud server 20 stores product files, sale files, etc. For example, the cloud server 20 may receive and store product files, sale files, etc. from a headquarters server (not shown) as appropriate.

The mobile terminal 60 is used by the customer when using service A. Specifically, the mobile terminal 60 is used when customer A registers products. In other words, customer A registers products using the mobile terminal 60. Customer A uses the POS terminal 40 to settle the bill.

The mobile terminal 60 has a communication function, an imaging function (camera), and also a recognition function that recognizes various codes (barcodes, two-dimensional codes, etc.). For example, the mobile terminal 60 recognizes barcodes attached to products. For example, the mobile terminal 60 may extract feature points in an image captured by the imaging function (an image acquired as a through image (live view)) and recognize objects (various codes).

The mobile terminal 60 displays various screens related to service A. For example, the mobile terminal 60 displays various screens related to service A by using an application program (hereinafter, also referred to as a specific app) that has been pre-installed (for example, downloaded and installed from the cloud server 20 or a dedicated server (not shown)) in order to use service A.

Although it is assumed that the mobile terminals 60 are basically owned by each customer, they may be loaned by the store. The number of mobile terminals 60 (the number in operation) varies depending on the number of customers, etc., and FIG. 1 shows two mobile terminals 60 as an example to show that multiple units are possible.

The POS terminal 40 is used by customers when using service A or service B. Specifically, the POS terminal 40 is used when customer A is paying. In other words, customer A uses the POS terminal 40 to pay for products that he has registered using the mobile terminal 60. The POS terminal 40 is also used when customer B is registering products and paying. In other words, customer B uses the POS terminal 40 to register products and pay. Details of the POS terminal 40 will be described later.

(Service A operation mode, Service B operation mode)
An operation mode in which the POS terminal 40 executes a process corresponding to service A for customer A (a settlement process for settling products registered using the mobile terminal 60) may be referred to as the "service A operation mode." An operation mode in which the POS terminal 40 executes a process corresponding to service B for customer B (product registration process and settlement process by the terminal itself) may be referred to as the "service B operation mode." The POS terminal 40 functions as a settlement device (self-service settlement device) when the operation mode is the service A operation mode, and functions as a registration settlement device (full-self-service registration settlement device) when the operation mode is the service B operation mode.

The transaction status management device 50 is a device that mainly manages various devices within the LAN 19. For example, the transaction status management device 50 monitors and controls the operating status of the POS terminal 40.

In addition to the self-services (service A and service B) described above, the sales system 1 may provide a service in which a store clerk uses a POS terminal 30 (not shown) to register products and then settle the bill, or a service in which a store clerk uses a POS terminal 31 (not shown) or a POS terminal 32 (not shown) to register products and then the customer settles the bill.

Figure 2 is a diagram explaining the POS terminal 40. Figure 2 (A) is a diagram showing an example of the appearance of the POS terminal 40 (front view seen from the customer side). Figure 2 (B) is a diagram showing an example of the configuration of the POS terminal 40. In Figures 2 (A) and 2 (B), the same parts are given the same reference numerals.

Below, an example of the configuration of the POS terminal 40 shown in FIG. 2(B) will be described with reference to FIG. 2(A). The POS terminal 40 comprises a CPU 401, a ROM 402, a RAM 403, a hard disk 404, a display unit 405, a scanner unit 406, a card payment unit 408, a change dispenser 409, a printing unit 413, an audio output unit 414, a communication unit 415, an imaging unit 416 (camera), and a sign pole 417. These can communicate with each other via a bus. The POS terminal 40 may further comprise a key operation unit made up of various mechanical keys (hard buttons), a sensor for detecting the presence of a person (such as a human sensor), etc.

The CPU 401 is a central processing unit that controls the operation of the POS terminal 40 by reading and executing programs stored in the ROM 402 .
The ROM 402 is a read-only memory, and stores various types of information used by the CPU 401, including programs.

RAM 403 is a read/write memory, and stores various information as a main storage device. For example, RAM 403 stores information read from ROM 402 or hard disk 404, information acquired from the outside, information generated during processing, etc.

The hard disk 404 stores various information as an auxiliary storage device. For example, the hard disk 404 may store programs executed by the CPU 401 instead of the ROM 402. Also, instead of the RAM 403, the hard disk 404 may store information read from the ROM 402, information obtained from the outside, information generated during processing, etc. Note that a storage device such as an SSD (Solid State Drive) may be provided instead of the hard disk 404.

The display unit 405 is a touch display that displays various information and accepts various inputs.

The scanner unit 406 optically reads various information. Specifically, the scanner unit 406 scans the code (a two-dimensional checkout code 605 (described later)) displayed on the display unit of the mobile terminal 60, and reads the information necessary for the checkout process. For example, the scanner unit 406 also scans the code attached to a product, and reads the product code (JAN code, etc.).

In addition to the above, the scanner unit 406 may scan a code attached to a store clerk's name tag or the like to read the store clerk code. The scanner unit 406 may also scan codes attached to gift certificates (gift certificates, coupons, preferential coupons) and various cards (e.g., membership cards, point cards, etc.) to read the respective information. The scanner unit 406 may also scan a code printed on an accounting ticket (registered trademark) printed and issued by another device (e.g., a POS terminal 31 (not shown) to read the information required for the settlement process.

As described above, the POS terminal 40 can register products using the scanner unit 406, but it may also be possible to register products without using the scanner unit 406. For example, the POS terminal 40 may display buttons (product preset buttons) corresponding to individual products on the display unit 405, and register the products corresponding to the buttons based on the operation (touch) of the buttons.

The card payment unit 408 is a payment mechanism that uses various cards (credit cards, prepaid cards such as transportation cards, cash cards for debit payments, point cards for point payments, etc.). The card payment unit 408 is equipped with a card recognition unit (reading unit), a display unit, and an operation unit, but it is sufficient that it is equipped with at least the card recognition unit. The card recognition unit may recognize various cards (e.g., point cards, membership cards, shareholder cards, etc.) for the purpose of granting benefits, discounts, etc.

The change dispenser 409 (cash settlement unit) is a cash settlement mechanism that has an input port for banknotes and coins and an output port for banknotes and coins, calculates the amount of money inserted into the input port, calculates the change amount, which is the difference between the input amount and the purchase amount, and outputs the change from the output port. When banknotes or coins are inserted into the input port, they are detected by a sensor (detecting that they have been inserted, detecting the number of coins by denomination, etc.).

The printing unit 413 prints and issues various media (receipts, etc.).
The audio output unit 414 outputs audio. For example, the audio output unit 414 outputs a confirmation sound, a warning sound, audio guidance, etc.

The communication unit 415 transmits and receives information to and from other devices (e.g., the store controller 10).
The imaging unit 416, for example, captures an image of the customer. The POS terminal 40 may include two or more imaging units 416, and may capture images of the face and hands (near the insertion and ejection openings of the change dispenser 409) at the same time.
The sign pole 417 has light emitting units (light emitting unit 417a, light emitting unit 417b, light emitting unit 417c) at the tip thereof, and notifies various information (calling a store clerk, operating status, etc.).

Figure 3 shows an example of the display of the mobile terminal 60. Figure 3 (A) is the start screen (menu screen) of service A. When using service A, the mobile terminal 60 displays a start screen such as that shown in Figure 3 (A). Various buttons are arranged on the start screen. For example, the start screen has a start shopping button BT600 that accepts an instruction to start shopping. When a customer starts shopping, he or she operates the start shopping button BT600. When the start shopping button BT600 is operated, the mobile terminal 60 displays the registration screen shown in Figure 3 (B) etc. instead of the start screen.

Figure 3 (B) is a registration screen (registration screen before registering one product; initial registration screen) that is displayed after the Start Shopping button BT600 is operated on the start screen of Figure 3 (A). The upper side of the registration screen is a captured image display area HR601 that mainly displays captured images. The lower side of the registration screen is a registration information display area HR602 that mainly displays product registration information.

Figure 3 (C) is the registration screen when capturing an image of the barcode attached to the first item of product (XX bread) on the registration screen of Figure 3 (B). In other words, when a customer registers a desired product (a product to be purchased), he or she captures an image of the barcode attached to the product, as shown in Figure 3 (C).

Figure 3 (D) is the registration screen (registration screen after product registration) after the registration of the first product (XX bread) is complete. Note that Figure 3 (D) shows the state immediately after the product has been identified (i.e., while the barcode is still being imaged), so the registration screen in Figure 3 (D) shows the barcode of the product displayed (imaged) in the image display area HR601.

The mobile terminal 60 displays the registration information of the product identified by imaging the barcode in the registration information display area HR602. For example, as shown in FIG. 3(D), the mobile terminal 60 displays the registration information (product name, quantity, price) of the product identified by imaging the barcode (XX bread) (symbol a), and displays the total information (total points, total price) (symbol b). The mobile terminal 60 displays part of the registration information (quantity) as a quantity button BT603. The quantity button BT603 is a button for changing the quantity.

When the mobile terminal 60 displays (adds) information about a scanned product in the registration information display area HR 602 as information about a certain transaction, the product is also stored (added) as information about the transaction (cart information) in the cloud server 20 through communication between the mobile terminal 60 and the cloud server 20. For example, the mobile terminal 60 may transmit a product code to the cloud server 20 each time it recognizes the product code from an imaged barcode, and the cloud server 20 may add the product code, etc. to the cart information of the transaction each time it receives a product code from the mobile terminal 60.

Furthermore, after registering a product (one item of product), the mobile terminal 60 displays the Proceed to Checkout button BT604, which accepts checkout instructions, in a display mode in which operation is enabled (shown by a solid line in FIG. 3(D)), as shown in FIG. 3(D). When the customer wishes to proceed to payment (checkout) (when completing product registration), they operate the Proceed to Checkout button BT604. When the Proceed to Checkout button BT604 is operated, the mobile terminal 60 displays the two-dimensional code display screen shown in FIG. 3(E) instead of the registration screen.

Figure 3 (E) is a two-dimensional code display screen that is displayed after the Proceed to Checkout button BT604 is operated on the registration screen of Figure 3 (D). A two-dimensional code 605 for checkout is displayed on the two-dimensional code display screen. The two-dimensional code 605 for checkout is a two-dimensional code of information required to execute the checkout process. For example, the two-dimensional code 605 for checkout may be a two-dimensional code of identification information (e.g., a Uniform Resource Identifier (URI)) for identifying the cart information of the transaction from among multiple pieces of cart information stored in the cloud server 20.

The two-dimensional code display screen also has an estimated total display area HR606 and a back button BT607. The back button BT607 is a button for returning to shopping (restarting shopping). When the back button BT607 is operated, the mobile terminal 60 displays a registration screen (the registration screen displayed immediately before the Proceed to Checkout button BT604 is operated) instead of the two-dimensional code display screen.

Figure 3 (F) shows how the POS terminal 40 reads the two-dimensional checkout code 605. When the POS terminal 40 reads the two-dimensional checkout code 605 displayed on the two-dimensional code display screen of the mobile terminal 60 using the scanner unit 406, it displays a checkout screen (product list screen; see Figure 6).

Figures 4 to 9 are examples of the display of the POS terminal 40. Figure 4 shows the standby screen (processing selection screen, initial screen) GM01. Before processing begins, the POS terminal 40 displays the standby screen GM01 as shown in Figure 4 on the display unit 405. The standby screen GM01 displays the message "Please select the button for the process you wish to use" and includes a self-checkout register selection button BT401, a full-self POS selection button BT402, a store clerk call button BT403, a balance inquiry button BT404, a language switch button BT405, a language switch button BT406, and a language switch button BT407, and is provided with a captured image display area HR408.

The self-checkout register selection button BT401 is a button that corresponds to Service A (Service A operation mode). In other words, the self-checkout register selection button BT401 is a button prepared for a customer (Customer A) who registers an item using the mobile terminal 60 and uses the POS terminal 40 to check out. In other words, a customer who registers an item using the mobile terminal 60 operates the self-checkout register selection button BT401 when starting checkout using the POS terminal 40.

The full-self-service POS selection button BT402 is a button that corresponds to Service B (Service B operation mode). In other words, the full-self-service POS selection button BT402 is a button prepared for a customer (Customer B) who uses the POS terminal 40 to register and pay for products. In other words, a customer who uses the POS terminal 40 to register and pay for products operates the full-self-service POS selection button BT402 when starting to register products using the POS terminal 40.

The clerk call button BT403 is a button for calling a clerk. The balance inquiry button BT404 is a button for inquiring about the balance of various cards. The language switch button BT405 is a button for switching the display (text) on the standby screen GM01 from Japanese to English. The language switch button BT406 is a button for switching to Chinese. The language switch button BT407 is a button for switching to Korean. The captured image display area HR408 displays a captured image of the periphery of the change dispenser 409 of the POS terminal 40. For example, the POS terminal 40 may output the captured image captured by the imaging unit 416 to the captured image display area 440 in real time (i.e. as a live view). The captured image may be a still image (for example, a still image displayed continuously).

Figure 5 shows the reading instruction screen GM02. When the self-checkout register selection button BT401 is operated on the standby screen GM01 shown in Figure 4, the POS terminal 40 displays the reading instruction screen GM02 as shown in Figure 5 on the display unit 405. The reading instruction screen GM02 displays a message saying "Please scan the two-dimensional code for checkout" and illustrates how the two-dimensional code for checkout is read. In addition, the reading instruction screen GM02 also has a store clerk call button BT403, a balance inquiry button BT404, and language switch buttons BT405, BT406, and BT407 arranged thereon, and also has a captured image display area HR408.

In other words, Customer A uses the mobile terminal 60 to register products (see Figures 3 (A) to 3 (D)), and when product registration is complete, he operates the Proceed to Checkout button BT604. When he operates the Proceed to Checkout button BT604, a two-dimensional checkout code 605 is displayed on the mobile terminal 60 (see Figure 3 (E)). Customer A also moves to the location of the POS terminal 40 to pay for the products he registered using the mobile terminal 60. Before processing begins, the POS terminal 40 displays the standby screen GM01 (Figure 4). The customer operates the self-checkout register selection button BT401 on the standby screen GM01 to pay for the products he registered using the mobile terminal 60. When he operates the self-checkout register selection button BT401, the POS terminal 40 displays the reading instruction screen GM02 (see Figure 5). The customer follows the message on the reading instruction screen GM02 to have the POS terminal 40 read the two-dimensional settlement code 605 displayed on the mobile terminal 60 (see Figure 3 (F)).

In the above description, the flow of operations performed by Customer A is described as a flow in which the two-dimensional checkout code 605 is displayed on the mobile terminal 60 and then the reading instruction screen GM02 is displayed on the POS terminal 40 (i.e., the flow is such that the proceed to checkout button BT604 is operated and then the self-checkout register selection button BT401 is operated), but the flow may also be such that the reading instruction screen GM02 is displayed on the POS terminal 40 and then the two-dimensional checkout code 605 is displayed on the mobile terminal 60 (i.e., the flow is such that the self-checkout register selection button BT401 is operated and then the proceed to checkout button BT604 is operated).

Figure 6 shows the product list screen GM05. When the POS terminal 40 reads the two-dimensional code 605 for payment displayed on the mobile terminal 60 on the reading instruction screen GM02 shown in Figure 5, the POS terminal 40 displays the product list screen GM05 as shown in Figure 6 on the display unit 405.

As will be described in detail later, the POS terminal 40 can also display the registration screen GM04 as shown in FIG. 9 after the full-self POS selection button BT402 is operated. However, the POS terminal 40 also displays the product list screen GM05 as shown in FIG. 6 on the display unit 405 when the Proceed to Checkout button BT414 is operated on the registration screen GM04 as shown in FIG. 9.

The product list screen GM05 displays the total number of items and the total amount, and has a checkout button BT420. The product list screen GM05 also displays a message saying "Please confirm the product details and press the checkout button," and has a product list display area HR410 and a price range registration number display area 411. The product list display area HR410 displays a list of registration information (product name, quantity, price) of products registered using the mobile terminal 60. In this example, since only one product (XX bread) was registered using the mobile terminal 60, only one product (XX bread) is displayed in the product list display area HR410. The price range registration number display area 411 displays the quantity for each price range. The product list screen GM05 also has a store clerk call button BT403, a balance inquiry button BT404, language switching buttons BT405, BT406, and BT407, and has a captured image display area HR408.

Figure 7 shows the payment type selection screen GM06. When the checkout button BT420 is operated on the product list screen GM05 shown in Figure 6, the POS terminal 40 displays the payment type selection screen GM06 as shown in Figure 7 on the display unit 405.

The payment type selection screen GM06 displays the total points and total amount, displays the message "Please select a payment method", and has a payment type selection area HR420 and a price range registration number display area 411. Various buttons corresponding to the payment type (payment method) are arranged in the payment type selection area HR420. The payment type selection screen GM06 also has a store clerk call button BT403, balance inquiry button BT404, language switch buttons BT405, BT406, BT407, and back button BT422 arranged, and has a captured image display area HR408. The back button BT422 is a button for returning to the previous display. In other words, operating the back button BT422 switches the display to the product list screen GM05 of FIG. 6.

For example, when a customer wishes to pay in cash, the customer operates the cash button on the payment type selection screen GM06. When the cash button is operated, the POS terminal 40 displays a deposit screen (not shown) on the display unit 405. The deposit screen (not shown) displays, for example, a message such as "Please insert money" and has a payment amount display area (area that displays the total amount) and a deposit amount display area (area that displays the amount deposited (inserted)). The deposit screen (not shown) also has a store clerk call button BT403, language switch buttons BT405, BT406, and BT407, and a captured image display area HR408.

The customer checks the deposit screen (not shown) and inserts cash into the slot of the change dispenser 409. When an amount of cash (deposit) equal to or greater than the purchase amount (total amount) is inserted, the POS terminal 40 displays the Finish (receipt) button on the deposit screen (not shown). When the Finish (receipt) button is operated, the POS terminal 40 calculates the change amount, which is the difference between the amount inserted (deposit) and the purchase amount.

When the amount deposited exceeds the purchase amount (i.e., when change is available), the POS terminal 40 displays a change screen (not shown) on the display unit 405 and discharges the change to the discharge outlet of the change dispenser 409. On the other hand, when the amount deposited does not exceed the purchase amount (i.e., when change is not available), the POS terminal 40 does not display the change screen (not shown), but displays a receipt screen (not shown) on the display unit 405 and prints and issues a receipt.

The change screen (not shown) displays, for example, a message such as "Please accept your change," and includes a store clerk call button BT403, language switching buttons BT405, BT406, and BT407, and an image display area HR408. When change is removed from the outlet of the change dispenser 409 (when a sensor such as a photosensor is installed near the outlet and the sensor recognizes an object (presumably a customer's hand)), the POS terminal 40 displays a receipt screen (not shown) on the display unit 405 and prints and issues a receipt.

The receipt screen (not shown) displays, for example, a message saying "Please accept your receipt." When the receipt is removed (when the POS terminal 40 detects the receipt being removed by a sensor or the like), it displays the standby screen GM01 (Figure 4) on the display unit 405.

On the other hand, if the customer wishes to pay by credit card, for example, the customer presses the credit button on the payment type selection screen GM06 and operates the card payment section 408 to settle the bill. The same applies when making other non-cash payments (e.g., prepaid cards, etc.).

Figure 8 shows the registration screen GM03 before the registration of one product item. When the full-self POS selection button BT402 is operated on the standby screen GM01 shown in Figure 4, the POS terminal 40 displays the registration screen GM03 shown in Figure 8 on the display unit 405. The registration screen GM03 is provided with a registration instruction information display area HR401, a registered product display area HR412, and a total information display area HR413. The registration screen GM03 also has a store clerk call button BT403, a balance inquiry button BT404, language switch buttons BT405, BT406, and BT407, and a captured image display area HR408.

The registration instruction information display area HR401 displays a message saying "Please register the product," and includes a product scan guidance information display area HR402 and a product preset button display area HR403.

The product scan guide information display area HR402 displays the message "Please hold the product's barcode close to the scanner to register it" and shows the position of the scanner unit 406. The product preset button display area HR403 displays the message "For products without a barcode, please select a product from below" and has product preset buttons for vegetables, fruits, etc. When the product preset button for vegetables (as well as fruits, etc.) is operated, the POS terminal 40 displays product preset buttons for individual products belonging to vegetables (e.g., carrots, cabbage, etc.). The registered product display area HR412 is an area that displays product registration information. The total information display area HR413 is an area that displays total information for registered products.

Figure 9 shows the registration screen GM04 after a product has been registered. Specifically, when XX bread is registered on the registration screen GM03 shown in Figure 8, the POS terminal 40 displays the registration screen GM04 as shown in Figure 9 on the display unit 405. As shown in Figure 9, the registration information related to XX bread is displayed in the registered product display area HR412 of the registration screen GM04. In addition, because the product has been registered, a button BT414 to proceed to checkout is placed on the registration screen GM04. In other words, the POS terminal 40 does not display the button BT414 to proceed to checkout before the first product item is registered, but displays the button BT414 to proceed to checkout after the first product item is registered. Similar to the control of the Proceed to Checkout button BT604 on the mobile terminal 60 (FIGS. 3(B) to 3(D)), the POS terminal 40 may display the Proceed to Checkout button BT414 in an invalid display mode (shown by dashed lines in FIG. 3(B) and (C)) before the first product is registered, and may display the Proceed to Checkout button BT414 in an invalid display mode (shown by solid lines in FIG. 3(D)) after the first product is registered.

When the customer wishes to proceed to checkout (to complete product registration), they operate the Proceed to Checkout button BT414. When the Proceed to Checkout button BT414 is operated, the POS terminal 40 displays the product list screen GM05 as shown in FIG. 6 on the display unit 405 instead of the registration screen GM04. The customer then checks the products on the product list screen GM05 (FIG. 6) and operates the Checkout button BT420. Next, the customer selects the desired payment type (payment method) on the payment type selection screen GM06 (FIG. 7) that is displayed after operating the Checkout button BT420, and performs checkout using that payment type.

As described above, in service A (self-service using the mobile terminal 60 for product registration and the POS terminal 40 for payment), the process for product registration on the mobile terminal 60 proceeds as shown in FIG. 3(A) → FIG. 3(B) → FIG. 3(C) → FIG. 3(D) → FIG. 3(E). On the POS terminal 40 side, after the self-checkout register selection button BT401 on the standby screen GM01 (FIG. 4) is operated and the two-dimensional code 605 for payment is read on the reading instruction screen (FIG. 5), the process proceeds as shown in FIG. 6 → FIG. 7 (not shown after the payment type is determined). On the other hand, in service B (self-service using the POS terminal 40 for both product registration and payment), after the full self-POS selection button BT402 on the standby screen GM01 (FIG. 4) is operated on the POS terminal 40 side, the process proceeds as shown in FIG. 8 → FIG. 9 → FIG. 6 → FIG. 7 (not shown after the payment type is determined).

Figure 10 is a flowchart showing an example of the operation of the POS terminal 40. The flowchart in Figure 10 shows a part of the processing of the POS terminal 40. It is assumed that the POS terminal 40 is displaying the standby screen GM01 (Figure 4) at the start of the flowchart in Figure 10. In other words, the POS terminal 40 displays the standby screen GM01 (Figure 4) on the display unit 405, and waits for an operation (operation of the self-checkout register selection button BT401) by Customer A (basically a customer who has already completed product registration using the mobile terminal 60 and is about to start checkout using the POS terminal 40) or an operation (operation of the full self-checkout selection button BT402) by Customer B (a customer who is about to start product registration and checkout using the POS terminal).

Step S1: The POS terminal 40 determines whether or not a self-checkout register has been selected. Specifically, if the self-checkout register selection button BT401 has been operated, the POS terminal 40 determines that a self-checkout register has been selected. If a self-checkout register has been selected (Step S1: YES), the POS terminal 40 proceeds to Step S3. If a self-checkout register has not been selected (Step S1: NO), the POS terminal 40 proceeds to Step S2.

Step S2: The POS terminal 40 determines whether or not a full-self-service POS has been selected. Specifically, if the full-self-service POS selection button BT402 has been operated, the POS terminal 40 determines that a full-self-service POS has been selected. If a full-self-service POS has been selected (step S2: YES), the process proceeds to step S6. If a full-self-service POS has not been selected (step S2: NO), the process returns to step S1.

In other words, if a customer (customer A) operates the self-checkout register selection button BT401, the POS terminal 40 advances processing to step S3, and if a customer (customer B) operates the full self-checkout POS selection button BT402, the POS terminal 40 advances processing to step S6.

Step S3: The POS terminal 40 issues an instruction to read the two-dimensional settlement code 605. Specifically, the POS terminal 40 displays the read instruction screen GM02 (FIG. 5) on the display unit 405 instead of the standby screen GM01 (FIG. 4). Then, proceed to step S4.

Step S4: The POS terminal 40 determines whether the two-dimensional settlement code 605 has been read. The POS terminal 40 reads the two-dimensional settlement code 605 when the customer (Customer A) holds the two-dimensional settlement code 605 (the two-dimensional settlement code 605 displayed on the mobile terminal 60) within the recognition area of the scanner unit 406 of the POS terminal 40 (FIG. 3(F)). If the two-dimensional settlement code 605 has been read (Step S4: YES), proceed to Step S5. If the two-dimensional settlement code 605 has not been read (Step S4: NO), repeat Step S4.

Step S5: Display the self-checkout checkout screen. Specifically, the POS terminal 40 displays the product list screen GM05 (FIG. 6) on the display unit 405 instead of the reading instruction screen GM02 (FIG. 5).

From step S5 onwards, the POS terminal 40 executes self-settlement in response to the operation of the customer (Customer A) (Service A operation mode). That is, when the Checkout button BT420 is present on the product list screen GM05 (Fig. 6), the POS terminal 40 displays the payment type selection screen GM06 (Fig. 7) on the display unit 405 instead of the product list screen GM05 (Fig. 6). Then, when one of the payment type buttons is operated on the payment type selection screen GM06 (Fig. 7), the POS terminal 40 executes settlement for that payment type (cash payment/non-cash payment). This flowchart then ends.

Step S6: Display the full self-service registration screen. Specifically, the POS terminal 40 displays the registration screen GM03 (FIG. 8) on the display unit 405 instead of the reading instruction screen GM02 (FIG. 5).

From step S6 onwards, the POS terminal 40 performs self-product registration and settlement in response to the operation of the customer (customer B) (service B operation mode). That is, when a product is registered on the registration screen GM03 (Fig. 8), the POS terminal 40 displays the registration screen GM04 (Fig. 9) on the display unit 405 instead of the registration screen GM03 (Fig. 8). Then, when the button BT414 for proceeding to checkout is operated on the registration screen GM04 (Fig. 9), the POS terminal 40 displays the product list screen GM05 (Fig. 6) on the display unit 405 instead of the registration screen GM04 (Fig. 9). Next, when the checkout button BT420 is present on the product list screen GM05 (Fig. 6), the POS terminal 40 displays the payment type selection screen GM06 (Fig. 7) on the display unit 405 instead of the product list screen GM05 (Fig. 6). Then, when one of the payment type buttons is pressed on the payment type selection screen GM06 (FIG. 7), the POS terminal 40 executes settlement for that payment type (cash payment/non-cash payment). This flowchart then ends.

(Another standby screen of the POS terminal 40)
4 on the display unit 405 and waits for an operation by customer A (operation of the self-checkout register selection button BT401) or an operation by customer B (operation of the full-self POS selection button BT402), but the standby screen displayed by the POS terminal 40 is not limited to the standby screen GM01. Other standby screens will be described below as modified examples.

(Variation 1)
Fig. 11 is a display example of the POS terminal 40. The POS terminal 40 may display a standby screen GM11 as shown in Fig. 11, instead of the standby screen GM01 shown in Fig. 4. The standby screen GM11 displays a message saying "For self-checkout registers, scanning the two-dimensional code is also OK" in addition to the message "Please select the button for the process you wish to use" on the standby screen GM01.

In the case of the modified example 1, the POS terminal 40 accepts the operation of the self-checkout register selection button BT401 or the reading of the two-dimensional checkout code 605 from customer A, and accepts the operation of the full self-checkout POS selection button BT402 from customer B. That is, in the case of the modified example 1, customer A may operate the self-checkout register selection button BT401 on the standby screen GM11 while the standby screen GM11 is displayed, or may read the two-dimensional checkout code 605 displayed on the mobile terminal 60. When the self-checkout register selection button BT401 is operated while the standby screen GM11 is displayed, the POS terminal 40 displays the reading instruction screen GM02 shown in FIG. 5. When the POS terminal 40 reads the two-dimensional checkout code 605 while the standby screen GM11 is displayed, the POS terminal 40 displays the product list screen GM05 shown in FIG. 6. Therefore, in the modified example 1, the reading instruction screen GM02 (FIG. 5) may not be displayed.

(Variation 2)
Fig. 12 is a display example of the POS terminal 40. The POS terminal 40 may display a standby screen GM21 as shown in Fig. 12 instead of the standby screen GM01 shown in Fig. 4. Instead of the message "Please select the button for the process you wish to use" on the standby screen GM01, the standby screen GM21 displays a message "Please select the process you wish to use", a message "For self-checkout registers, scan the two-dimensional code", or a message "For full self-checkout POS, press the button on the right". Furthermore, the standby screen GM21 does not have a self-checkout register selection button BT401, and instead has a two-dimensional code scan guide information display area HR431 for checkout.

The settlement two-dimensional code scan guidance information display area HR431 is an area that provides guidance on reading the settlement two-dimensional code 605 by the scanner unit 406. The settlement two-dimensional code scan guidance information display area HR431 illustrates how the settlement two-dimensional code is read.

In the case of variant 2, the POS terminal 40 accepts the reading of the two-dimensional checkout code 605 from customer A, and accepts the operation of the full-self POS selection button BT402 from customer B. That is, in the case of variant 2, customer A reads the two-dimensional checkout code 605 displayed on the mobile terminal 60 while the standby screen GM21 is displayed. When the POS terminal 40 reads the two-dimensional checkout code 605 while the standby screen GM21 is displayed, it displays the product list screen GM05 shown in FIG. 6. Therefore, in variant 2, the read instruction screen GM02 (FIG. 5) is unnecessary.

(Variation 3)
13 is a display example of the POS terminal 40. The POS terminal 40 may display a standby screen GM31 as shown in FIG. 13 instead of the standby screen GM01 shown in FIG. 4. Instead of the message "Please select the button for the process you wish to use" on the standby screen GM01, the standby screen GM31 displays a message "Please select the process you wish to use", a message "For self-checkout registers, press the button on the left", or a message "For full self-POS, please register the product". Furthermore, the standby screen GM31 does not have a full self-POS selection button BT402, and instead has a registration instruction information display area HR432 (similar to the registration instruction information display area HR401 of the registration screen GM03 shown in FIG. 8).

In the case of variant 3, the POS terminal 40 accepts operation of the self-checkout register selection button BT401 from customer A, and accepts product registration (scanning and operation of the product preset button) from customer B. That is, in the case of variant 3, customer B registers a product while the standby screen GM31 is displayed. When a product is registered while the standby screen GM31 is displayed, the POS terminal 40 displays the registration screen GM04 shown in FIG. 9 (i.e., the registration screen after the product has been registered). Therefore, in variant 3, the registration screen GM03 (FIG. 8) before the registration of one product item is unnecessary.

(Variation 4)
14 is a display example of the POS terminal 40. The POS terminal 40 may display a standby screen GM41 as shown in FIG. 14 instead of the standby screen GM01 shown in FIG. 4. Instead of the message "Please select the button for the process you wish to use" on the standby screen GM01, the standby screen GM41 displays a message "Please select the process you wish to use", a message "For self-checkout registers, scan the two-dimensional code", and a message "For full self-POS, register the product". In addition, the standby screen GM41 does not have a self-checkout register selection button BT401 or a full self-POS selection button BT402, but instead has a two-dimensional code scan guide information display area HR431 for checkout similar to the standby screen GM21 in FIG. 12 and a registration instruction information display area HR432 similar to the standby screen GM31 in FIG. 13.

In the case of the modified example 4, the POS terminal 40 accepts the reading of the two-dimensional code 605 for payment from customer A and accepts the registration of a product (scanning, operating the product preset button) from customer B. That is, in the case of the modified example 4, customer A reads the two-dimensional code 605 for payment displayed on the mobile terminal 60 while the standby screen GM41 is displayed, and customer B registers a product while the standby screen GM41 is displayed. When the two-dimensional code 605 for payment is read while the standby screen GM41 is displayed, the POS terminal 40 displays the product list screen GM05 shown in FIG. 6, and when a product is registered while the standby screen GM41 is displayed, the registration screen GM04 shown in FIG. 9 (i.e., the registration screen after the product is registered) is displayed. Therefore, in the modified example 4, the reading instruction screen GM02 (FIG. 5) and the registration screen GM03 (FIG. 8) before the registration of one product item are not necessary.

(Variation 5)
Fig. 15 is a display example of the POS terminal 40. The POS terminal 40 may display a standby screen GM51 as shown in Fig. 15, instead of the standby screen GM01 shown in Fig. 4. Instead of the message "Please select the button for the process you wish to use" on the standby screen GM01, the standby screen GM51 displays a message such as "Please select the process you wish to use", "For self-checkout registers, select the button on the left", or "For full self-service POS, press the button to select whether or not you need a shopping bag". Furthermore, the standby screen GM51 does not have a full self-service POS selection button BT402, and instead has a shopping bag related information display area HR442.

The plastic bag related information display area HR442 is an area where the customer is asked whether or not they need a plastic bag. The plastic bag related information display area HR442 displays the message "Do you need a plastic bag?" and has a "No need" button BT441 and a "Need" button BT442 arranged.

In the case of the modified example 5, the POS terminal 40 accepts the operation of the self-checkout register selection button BT401 from customer A, and accepts the operation of whether or not a shopping bag is required from customer B (the operation of the no need button BT441 or the required button BT442). That is, in the case of the modified example 5, customer B first operates whether or not a shopping bag is required while the standby screen GM51 is displayed. If the no need button BT441 is operated while the standby screen GM51 is displayed, the POS terminal 40 displays the registration screen GM03 shown in FIG. 8 (i.e., the registration screen before the product is registered). If the required button BT442 is operated while the standby screen GM51 is displayed, the POS terminal 40 displays the registration screen GM04 shown in FIG. 9 (i.e., the registration screen after the shopping bag is registered). Therefore, in the modified example 5, the registration screen GM03 (FIG. 8) before the registration of one product may not be displayed.

When multiple types of plastic bags with different sizes, etc. are available, the POS terminal 40 may display a screen for accepting the selection of the type of plastic bag (plastic bag selection screen) when the Required button BT442 is operated, and after one type of plastic bag is selected on the plastic bag selection screen, display the registration screen GM04 shown in FIG. 9 (the registration screen after the registration of that type of plastic bag). Also, in the plastic bag-related information display area HR442, a button for each type of plastic bag may be arranged instead of the Required button BT442, and the POS terminal 40 may display the registration screen GM04 shown in FIG. 9 (the registration screen after the registration of that type of plastic bag) when the button for one type of plastic bag is operated. The same applies to the sixth modification (standby screen GM61).

(Variation 6)
16 is a display example of the POS terminal 40. The POS terminal 40 may display a standby screen GM61 as shown in FIG. 16 instead of the standby screen GM01 shown in FIG. 4. Instead of the message "Please select the button for the process you wish to use" on the standby screen GM01, the standby screen GM61 also displays a message "Please select the process you wish to use", a message "For self-checkout registers, scan the two-dimensional code", and a message "For full-self POS, press the selection button for whether or not you need a shopping bag". Furthermore, the standby screen GM61 does not have the self-checkout register selection button BT401 or the full-self POS selection button BT402, but instead has a two-dimensional code scan guide information display area HR431 for checkout similar to the standby screen GM21 in FIG. 12 and a shopping bag related information display area HR442 similar to the standby screen GM51 in FIG. 15.

In the case of the modified example 6, the POS terminal 40 accepts the reading of the two-dimensional code 605 for payment from the customer A and accepts an operation of whether or not a shopping bag is required from the customer B. That is, in the case of the modified example 6, the customer A reads the two-dimensional code 605 for payment displayed on the mobile terminal 60 while the standby screen GM61 is displayed, and the customer B first operates whether or not a shopping bag is required while the standby screen GM61 is displayed. When the two-dimensional code 605 for payment is read while the standby screen GM61 is displayed, the POS terminal 40 displays the product list screen GM05 shown in FIG. 6, when the unnecessary button BT441 is operated while the standby screen GM61 is displayed, the registration screen GM03 shown in FIG. 8 is displayed, and when the necessary button BT442 is operated while the standby screen GM61 is displayed, the registration screen GM04 shown in FIG. 9 is displayed. Therefore, in the modified example 6, the reading instruction screen GM02 (FIG. 5) is not required. Also, in variant example 6, the registration screen GM03 (Figure 8) before registering the first product item may not be displayed.

(Other operations in the standby screen GM01 to the standby screen GM61)
(a1) The standby screen GM01 (FIG. 4) may enable the reading of the two-dimensional settlement code 605. In other words, the standby screen GM01 does not display a message regarding the reading of the two-dimensional settlement code 605, but may accept the reading of the two-dimensional settlement code 605 by customer A. In an aspect in which the standby screen GM01 enables the reading of the two-dimensional settlement code 605, when the two-dimensional settlement code 605 is read, the POS terminal 40 displays the product list screen GM05 (FIG. 6) without displaying the reading instruction screen GM02 (FIG. 5).

(a2) In relation to (a1) above, similar to the standby screen GM01 (FIG. 4) in (a1) above, it may be possible to read the two-dimensional settlement code 605 on the standby screen GM31 (FIG. 13) or the standby screen GM51 (FIG. 15).

(b1) It may be possible to register a product on the standby screen GM01 (FIG. 4). In other words, the standby screen GM01 may not display a message regarding product registration, but may accept product registration by customer B. In a mode in which product registration is possible on the standby screen GM01, when a product is registered, the POS terminal 40 displays the registration screen GM04 shown in FIG. 9 (i.e., the registration screen after the product has been registered).

(b2) In relation to (b1) above, similar to the standby screen GM01 (FIG. 4) in (b1) above, product registration may be enabled on the standby screen GM11 (FIG. 11) and the standby screen GM21 (FIG. 12).

(b3) In relation to (b1) above, similar to the standby screen GM01 (FIG. 4) in (b1) above, product registration may be enabled on the standby screen GM51 (FIG. 15) and the standby screen GM61 (FIG. 16). In addition, after product registration, the customer may be subsequently inquired about the need for a shopping bag on the registration screen GM04 (FIG. 9).

(c1) When a registration operation for a membership card (including a point card) or gift certificates (gift certificates, coupons, preferential coupons) is performed on the standby screen GM01 (FIG. 4) (such as when the code information attached to each medium is read), the registration operation may be invalidated, or the registration operation may be valid (the information from the registration operation may be stored to be handed over to subsequent processing), and information may be displayed indicating that the user should operate according to the instructions on that screen (standby screen GM01) (the user should operate the self-checkout register selection button BT401 or the full self-POS selection button BT402). Note that when the registration information is invalidated, information may be displayed indicating that the user should operate according to the instructions on that screen, along with error information (read error).

(c2) In relation to (c1) above, similar to the standby screen GM01 (FIG. 4) in (c1) above, when a registration operation for a membership card or gift certificate is performed on each of the standby screens GM11 (FIG. 11) to GM61 (FIG. 16), the registration operation may be invalidated, or the registration operation may be valid, and information may be displayed to the effect that the operation should be performed according to the instructions on the respective screen. Note that, when the registration information is invalidated, information may be displayed to the effect that the operation should be performed according to the instructions on the screen, along with error information (read error). Note that, although this is related to (c3) below, in this (c2), the standby screen is not switched.

(c3) In relation to (c1) above, when a registration operation for a member card or gift certificate is performed on each of the standby screens GM21 (FIG. 12) to GM41 (FIG. 14), the registration operation may be invalidated, or the registration operation may be valid, and the standby screen GM01 (FIG. 4) or the standby screen GM11 (FIG. 11) may be displayed. In other words, among the standby screens (standby screens GM21 to GM61) that do not display at least one of the self-checkout register selection button BT401 or the full self-service POS selection button BT402, the standby screens (standby screens GM21 to GM41) that do not first check whether a shopping bag is needed may display a standby screen (standby screen GM01, standby screen GM11) that displays both the self-checkout register selection button BT401 and the full self-service POS selection button BT402, if an operation that is not originally planned (such as a registration operation for a member card in this example) is performed.

(Other controls related to the standby screen)
In the above, an example was described in which the POS terminal 40 switches between the self-checkout register (service A operation mode) and the full-self-service POS (service B operation mode) based on the operation (including the operation) of the customer (customer A, customer B) on the standby screens GM01 to GM61, but the POS terminal 40 may switch between the self-checkout register (service A operation mode) and the full-self-service POS (service B operation mode) without the customer's operation. Also, in the above, an example was described in which the POS terminal 40 displays a standby screen (standby screens GM01 to GM61) that is compatible with both the self-checkout register (service A operation mode) and the full-self-service POS (service B operation mode) (waiting for both customer A and customer B) before starting processing, but the POS terminal 40 may display a standby screen that is compatible only with the self-checkout register (service A operation mode) (waiting only for customer A) or a standby screen that is compatible only with the full-self-service POS (service B operation mode) (waiting only for customer B) before starting processing. Below, we will explain other controls, such as control to switch between self-checkout registers (service A operation mode) and full-self-service POS (service B operation mode) without customer operation, and control to display a standby screen that is compatible only with self-checkout registers (service A operation mode) or a standby screen that is compatible only with full-self-service POS (service B operation mode).

(Common standby screen, Service A standby screen, Service B standby screen)
In the following description, the standby screens (specifically, standby screens GM01 to GM61 (hereinafter, standby screen GM01, etc.)) that are compatible with both self-checkout registers (service A operation mode) and full self-service POS (service B operation mode) may be referred to as common standby screens. In contrast to the common standby screens, standby screens that are compatible only with self-checkout registers (service A operation mode) may be referred to as service A standby screens (not shown), and standby screens that are compatible only with full self-service POS (service B operation mode) may be referred to as service B standby screens (not shown). Like the common standby screen, the service A standby screen (similarly the service B standby screen) is displayed after processing is completed (e.g., in place of the receipt screen).

The Service A standby screen may have a self-checkout register selection button BT401 (Figure 4, etc.) and may have a checkout 2D code scan guidance information display area HR431 (Figure 12, etc.). The Service B standby screen may have a full-self POS selection button BT402 (Figure 4, etc.) and may have a registration instruction information display area HR432 (Figure 13, etc.) and may have a shopping bag related information display area HR442 (Figure 15, etc.).

The service A standby screen may be the reading instruction screen (Figure 5). In other words, the reading instruction screen may be referred to as the service A standby screen. The service B standby screen may be the registration screen GM03 (Figure 8) before the registration of the first product item. In other words, the registration screen GM03 may be referred to as the service B standby screen.

(Common standby mode, Service A standby mode, Service B standby mode)
In the following description, a display mode that displays a common standby screen as the standby screen may be referred to as a common standby mode, a display mode that displays a service A standby screen as the standby screen may be referred to as a service A standby mode, and a display mode that displays a service B standby screen as the standby screen may be referred to as a service B standby mode.

(Control 1)
The POS terminal 40 may control the standby mode (common standby mode, service A standby mode, service B standby mode) based on time (preset schedule information). In other words, the POS terminal 40 may control the display of the standby screen (common standby screen (standby screen GM01, etc.), service A standby screen, service B standby screen) based on time. Note that the schedule information may be stored in the POS terminal 40, or may be stored in another device that the POS terminal 40 can refer to (e.g., the transaction status management device 50, the store controller 10, the cloud server 20, etc.).

For example, if six POS terminals 40 (POS terminal 40a to POS terminal 40f) are installed in a store and service A is available for use during part of business hours (for example, business hours are 8:00 to 22:00 and service A is available for use during 10:00 to 20:00), control may be performed as follows: Outside the hours when service A is available (8:00 to 10:00, 20:00 to 22:00), all six POS terminals 40 (POS terminal 40a to POS terminal 40f) are controlled to service B standby mode (displaying the service B standby screen as the standby screen). On the other hand, during the hours during which service A is available (10:00-20:00), two POS terminals 40 (e.g., POS terminals 40a and 40b) are controlled to service A standby mode (displaying the service A standby screen as the standby screen), two other POS terminals 40 (e.g., POS terminals 40c and 40d) are controlled to service B standby mode (displaying the service B standby screen as the standby screen), and the remaining two POS terminals 40 (POS terminals 40e and 40f) are controlled to common standby mode (displaying the common standby screen as the standby screen). In other words, POS terminals 40a and 40b are controlled to service A standby mode during the hours during which service A is available, and are controlled to service B standby mode outside the hours during which service A is available. POS terminals 40c and 40d are controlled to service B standby mode all day. POS terminals 40e and 40f are controlled to common standby mode during the hours when service A is available, and are controlled to service B standby mode outside the hours when service A is available.

If the customer is not using the terminal at the time to switch the standby mode (standby screen), the standby mode may be switched to the standby mode at that time, and if the customer is using the terminal at the time to switch the standby mode, the standby mode may be switched to the standby mode after the customer's processing is completed. For example, the POS terminal 40a is set to switch the standby mode from the service B standby mode to the service A standby mode at 10 o'clock, and if the customer is not using the POS terminal 40a at 10 o'clock, the standby screen may be switched from the service B standby screen to the service A standby screen at that time (the standby screen being displayed may be switched from the service B standby screen to the service A standby screen), and if the customer is using the POS terminal 40a at 10 o'clock, the service A standby screen may be displayed after the customer's processing is completed. Also, for example, the POS terminal 40e is set to switch from the common standby mode to the service B standby mode at 8 p.m., but if the customer is not using the POS terminal 40e at 8 p.m., the common standby screen is switched to the service B standby screen at that time (the standby screen being displayed is switched from the common standby screen to the service B standby screen), and if the customer is using the POS terminal 40e at 8 p.m., the service B standby screen may be displayed after the customer's processing is completed.

...

(Control 2)
The POS terminal 40 may control the standby mode (display of the standby screen) based on the usage status of service A instead of or in addition to the time.

For example, the standby mode may be controlled according to the number of customers A shopping in the store (i.e., the number of people using mobile terminals 60 to register products in the store). For example, if the number of customers A shopping in the store is equal to or greater than a predetermined number during the available time of service A, the number of POS terminals 40 controlled to the service A standby mode may be increased, and if the number of customers A shopping in the store is less than the predetermined number, the number of POS terminals 40 controlled to the service A standby mode may be decreased. Alternatively, if the number of customers A shopping in the store is equal to or greater than a predetermined number during the available time of service A, the number of POS terminals 40 controlled to the service A standby mode or the common standby mode may be increased, and if the number of customers A shopping in the store is less than the predetermined number, the number of POS terminals 40 controlled to the service A standby mode or the common standby mode may be decreased.

The POS terminal 40 may grasp the number of customer A shopping in the store by communicating with the cloud server 20. For example, the cloud server 20 may notify the POS terminal 40 of the number of customer A shopping in the store in response to an inquiry from the POS terminal 40, or appropriately (when the number of customer A present in the store increases or decreases, or every time a predetermined time (e.g., 10 seconds) has passed). In addition, the cloud server 20 may add the number of customer A shopping in the store when it receives a notification from the mobile terminal 60 that the Start Shopping button BT600 (FIG. 3(A)) has been operated (when the registration screen in FIG. 3(B) is displayed), and may subtract the number of customer A shopping in the store when it receives a notification from the mobile terminal 60 that the Proceed to Checkout button BT604 (FIG. 3(D)) has been operated (when the two-dimensional code display screen in FIG. 3(E) is displayed). The cloud server 20 may add the number of customer A shopping in the store when it receives a notification that the Start Shopping button BT600 has been operated from a mobile terminal 60 located at the store's location (the mobile terminal 60 located at the store's location is identified by GPS or the like), and may subtract the number of customer A shopping in the store when it receives a notification that the Proceed to Checkout button BT604 has been operated from a mobile terminal 60 located at the store's location. The POS terminal 40 may identify the number of customer A shopping in the store by other methods (wireless LAN, etc.).

For example, the standby mode (display of the standby screen) may be controlled depending on the shopping status of customer A who is shopping in the store (specifically, whether or not it is close to the time to pay).

For example, by focusing on the relationship between the number of purchases and the closeness of settlement, the standby mode may be controlled according to the number of customers A in the store who have purchased a predetermined number of points or more. For example, if the number of customers is equal to or greater than the predetermined number, the number of POS terminals 40 controlled to the service A standby mode (or the number of POS terminals 40 controlled to the service A standby mode or the common standby mode) may be increased, and if the number of customers is less than the predetermined number, the number may be decreased. The predetermined number may be set according to the time period, day of the week, sale date, etc. The predetermined number may also be set for each customer A based on their past purchase history, attributes (gender, age), etc.

In addition, by focusing on the relationship between the purchase amount (total amount) and the closeness of settlement, the standby mode may be controlled according to the number of customers A in the store whose purchase amount is equal to or exceeds a predetermined amount. For example, if the number of customers is equal to or exceeds a predetermined number, the number of POS terminals 40 controlled to the service A standby mode (or the number of POS terminals 40 controlled to the service A standby mode or the common standby mode) may be increased, and if the number of customers is less than the predetermined number, the number may be decreased. The predetermined amount may be set according to the time period, day of the week, sale day, etc. In addition, the predetermined amount may be set for each customer A based on past purchase history, attributes (gender, age), etc.

In addition, by focusing on the relationship between the time spent in the store (purchase time) and the closeness of checkout, the standby mode may be controlled according to the number of customers A in the store who have stayed in the store for a predetermined time or more. For example, if the number of customers is equal to or greater than a predetermined number, the number of POS terminals 40 controlled to the service A standby mode (or the number of POS terminals 40 controlled to the service A standby mode or the common standby mode) may be increased, and if the number of customers is less than the predetermined number, the number may be decreased. The predetermined time may be set according to the time period, day of the week, sale day, etc. The predetermined time may also be set for each customer A based on their past purchase history, attributes (gender, age), etc.

Also, by focusing on the relationship between in-store location and proximity to checkout, the standby mode may be controlled according to the number of Customer A in the store who are at the end of the traffic line (aisle) (identified, for example, by GPS, wireless LAN, etc.). For example, if the number of customers is equal to or greater than a predetermined number, the number of POS terminals 40 controlled to service A standby mode (or the number of POS terminals 40 controlled to service A standby mode or common standby mode) may be increased, and if the number of customers is less than the predetermined number, the number may be decreased. The location of Customer A in the store may be identified, for example, by wireless LAN, etc.

(Control 3)
Instead of or in addition to the above, the POS terminal 40 may control the standby mode (display of the standby screen) based on the approach of customer A or the like.

For example, the standby mode may be controlled based on receiving (via another device or directly) information transmitted from a shopping cart (or an electronic device built into or external to the shopping cart) used for service A. As an example, if the POS terminal 40 is displaying a service B standby screen at the time when it receives identification information (shopping cart number, electronic device number) that identifies the shopping cart (or an electronic device built into or external to the shopping cart) from the shopping cart (or an electronic device built into or external to the shopping cart), it may switch from the service B standby screen to the service A standby screen (or a common standby screen), and if it is displaying a common standby screen at the above timing, it may switch from the common standby screen to the service A standby screen. The same applies to the case where information transmitted from a shopping cart (or an electronic device built into or external to the shopping cart) used for service A is received (via another device or directly).

The approach of customer A may be determined based on location information or beacon control. When the direction and distance of the mobile terminal 60 can be recognized (for example, when Bluetooth (registered trademark) 5.1 is used), the POS terminal 40 may switch to the service A standby screen or the common standby screen when it recognizes the presence of the mobile terminal 60 in a predetermined direction (toward the sales floor) and within a predetermined distance (for example, several dozen meters) from the POS terminal 40. Furthermore, in addition to the presence of the mobile terminal 60, each mobile terminal 60 (i.e., each customer A) may be recognized and the switching of the standby screen may be controlled. For example, the UID (User Identifier) may be referenced to control the switching of the standby screen. As an example, a standby screen suitable for customer A (service A standby screen or common standby screen; or, for the common standby screen, one of the standby screens GM11 to GM61, which will be described in detail later) may be displayed based on the past operation time of the customer A. The UID may be a customer number for service A that is assigned to each customer A when they become a new customer of service A (when a customer who is not an A customer becomes an A customer), for example, when they install a specific app.

The standby mode may also be controlled based on the recognition of information attached to a plastic bag used for service A (e.g., a plastic bag exclusively for service A that is sold near the entrance). For example, if the POS terminal 40 is displaying a service B standby screen at the time when the imaging unit 416 recognizes a predetermined pattern (such as the symbol mark of service A) printed on a plastic bag exclusively for service A, the POS terminal 40 may switch from the service B standby screen to the service A standby screen (or a common standby screen), and if the common standby screen is displayed at the above timing, the POS terminal 40 may switch from the common standby screen to the service A standby screen.

Incidentally, if the POS terminal 40 can recognize the approach of customer A (the presence of customer A), the information attached to the shopping bag for service A is not limited to a predetermined pattern. For example, a code such as a two-dimensional code is printed on the shopping bag for service A, and if the POS terminal 40 is displaying the service B standby screen at the time when the scanner unit 406 recognizes the code printed on the shopping bag for service A, the POS terminal 40 may switch from the service B standby screen to the service A standby screen (or the common standby screen), and if the common standby screen is displayed at the above timing, the POS terminal 40 may switch from the common standby screen to the service A standby screen. In addition, if it is possible to recognize that customer A is approaching, a shopping bag other than the one for service A may be used. For example, a shopping basket for service A (a shopping basket with the same information attached to the shopping bag for service A) or a my-bag for service A (a my-bag with the same information attached to the shopping bag for service A) may be used.

(Control 4)
Instead of or in addition to the above, the POS terminal 40 may control the standby mode (display of the standby screen) based on an operation on the POS terminal 40 .

For example, the standby screen may be changed based on the operation of the store clerk (such as a special operation that the customer is not aware of, or an operation that requires the clerk card to be read before the operation).

(Control 5)
Alternatively or additionally, the POS terminal 40 may control the standby mode (display of the standby screen) based on the operation of a store clerk on another device (for example, the transaction status management device 50).

For example, the transaction status management device 50 may change the standby mode of a POS terminal 40 by updating schedule information referenced by the POS terminal 40 based on the operation of a store clerk. Also, for example, the transaction status management device 50 may change the standby mode of a POS terminal 40 by sending a standby screen change command to the POS terminal 40 based on the operation of a store clerk. Note that if the POS terminal 40 receives a standby screen change command when it is not in use by a customer, it may change the standby screen in accordance with the standby screen change command at the time it receives the standby screen change command, and if it receives a standby screen change command when it is in use by a customer, it may display the standby screen in accordance with the standby screen change command after the customer's processing is completed.

The above-mentioned controls (Control 1 to Control 5) relate to switching of standby screens between the common standby mode, the service A standby mode, and the service B standby mode, but may also be applied to switching of standby screens within the common standby mode. In other words, each POS terminal 40 is capable of displaying one of a number of types of common standby screens (e.g., standby screens GM01 to GM61), and the POS terminal 40 may control which common standby screen to display based on time as in Control 1, based on the usage status of service A as in Control 2, based on the approach of customer A as in Control 3, based on an operation on the POS terminal 40 as in Control 4, or based on an operation on another device as in Control 5.

(Notification by signage)
Signage (display) may be installed in the store to inform (display) customers (customer A, customer B) of how to operate the POS terminal 40. The signage is connected to the LAN 19, and the display contents may be managed (controlled) by the transaction status management device 50, for example.

For example, customer A may be notified that he needs to operate the self-checkout register selection button BT401 (or read the checkout two-dimensional code 605) on the POS terminal 40, and customer B may be notified that he needs to operate the full-self POS selection button BT402 (or register a product or select a shopping bag) on the POS terminal 40. Note that while the notification may be made using paper media such as a poster, the required operation (permitted operation) differs depending on the type of standby screen (service A standby screen, service B standby screen, standby screen GM01, standby screen GM11, standby screen GM21, standby screen GM31, standby screen GM41, standby screen GM51, standby screen GM61), and the standby screen can also be switched, so notification using signage is preferable.

Customers (customer A, customer B) waiting at the register (waiting to operate the POS terminal 40) and store clerks (guide staff) may be notified (displayed) of the current standby mode (standby screen) of each POS terminal 40. For example, as described above, if six POS terminals 40 (POS terminals 40a to 40f) are installed in a store, signage may be used to notify that currently (for example, as of 7:55 p.m.), POS terminals 40a and 40b are in service A standby mode (displaying the service A standby screen), POS terminals 40c and 40d are in service B standby mode (displaying the service B standby screen), and POS terminals 40e and 40f are in common standby mode (displaying the common standby screen).

Instead of or in addition to the current standby mode (standby screen) of each POS terminal 40, customers (Customer A, Customer B) waiting at the register (waiting to operate the POS terminal 40) and store clerks (guide staff) may be notified (displayed) of the future standby mode (standby screen) of each POS terminal 40 (for example, within the next 10 minutes). For example, as described above, if six POS terminals 40 (POS terminal 40a to POS terminal 40f) are installed in a store, signage may be used to notify that POS terminal 40a and POS terminal 40b are scheduled to switch from service A standby mode to service B standby mode (the standby screen is scheduled to switch from the service A standby screen to the service B standby screen) in five minutes (for example, five minutes after 19:55, at 20:00), and that POS terminal 40e and POS terminal 40f are scheduled to switch from common standby mode to service B standby mode (the standby screen is scheduled to switch from the common standby screen to the service B standby screen).

In place of or in addition to the above, the operation mode of the POS terminal 40 in process may be notified (displayed) to customers (customer A, customer B) waiting at the register (waiting to operate the POS terminal 40) and store clerks (guide staff). For example, as described above, if six POS terminals 40 (POS terminals 40a to 40f) are installed in a store, signage may be used to notify that currently (for example, as of 7:55 p.m.), POS terminal 40a is operating in service A operation mode (service A checkout process is being performed), POS terminal 40c is operating in service B operation mode (service B product registration process is being performed), POS terminal 40d is operating in service B operation mode (service B checkout process is being performed), and POS terminal 40e is operating in service A operation mode (service A checkout process is being performed).

Alternatively or additionally, the suitable POS terminal 40 may be notified (displayed) to customers (customer A, customer B) waiting at the register (waiting to operate the POS terminal 40) and store clerks (guide staff). For example, as described above, when six POS terminals 40 (POS terminals 40a to 40f) are installed in a store, signage may be used to notify customer A that POS terminals 40a and 40b, which are currently (for example, as of 19:00), controlled in service A standby mode, are suitable, and that POS terminals 40e and 40f, which are controlled in common standby mode, are also suitable, and to notify customer B that POS terminals 40c and 40d, which are currently (for example, as of 19:00), controlled in service B standby mode are suitable, and that POS terminals 40e and 40f, which are controlled in common standby mode, are also suitable.

(Notification by the transaction status management device 50, etc.)
Instead of or in addition to the notification using signage, the transaction status management device 50 may display the current standby mode (standby screen) of each POS terminal 40, the future standby mode (standby screen) of each POS terminal 40, the operation mode of the POS terminal 40 currently in process, and information regarding a suitable POS terminal 40. Also, the above-mentioned information may be notified (displayed) on a mobile terminal (smartphone, tablet terminal, etc.) carried by the store clerk.

(Notification by sign pole 417)
Instead of or in addition to the above-mentioned notifications, various information such as the current standby mode (standby screen) may be notified (output) by using the light-emitting parts (light-emitting parts 417a, 417b, 417c) of the sign pole 417 of each POS terminal 40. For example, as shown in the following (1) to (8), various information may be notified by the light-emitting state of the light-emitting part of the sign pole 417. In other words, the light-emitting state of the light-emitting part of the sign pole 417 may be changed depending on the notification content.

(1) The POS terminal 40 may, during standby or processing, change the light emission state of the light-emitting part of the sign pole 417 depending on the standby mode that is controlled (set). In other words, the light emission state of the light-emitting part of the sign pole 417 may be changed depending on whether the POS terminal 40 is controlled to the common standby mode, the service A standby mode, or the service B standby mode.
(2) During processing, the POS terminal 40 may change the light emission state of the light-emitting part of the sign pole 417 depending on the operation mode being operated. In other words, the light emission state of the light-emitting part of the sign pole 417 may be changed when operating in the service A operation mode (when the settlement process of service A is being performed) and when operating in the service B operation mode (when the product registration process and settlement process of service B are being performed).
(3) In relation to (2), when operating in service B operation mode, the light emission pattern of the light-emitting part of the sign pole 417 may be made different when a product registration process is being performed and when a payment process is being performed.
(4) During a settlement process, the POS terminal 40 may change the light emission state of the light-emitting part of the sign pole 417 depending on the settlement type (payment method). For example, the light emission state of the light-emitting part of the sign pole 417 may be changed depending on whether the settlement process is performed by cash settlement or non-cash settlement.
(5) In relation to (4), when settlement processing is performed by cash payment, the light-emitting state of the light-emitting part of the sign pole 417 may be made different between the case of cash payment in the service A operation mode (settlement processing for service A) and the case of cash payment in the service B operation mode (settlement processing for service B).
(6) In relation to (4), when settlement processing is performed by non-cash payment, the light-emitting state of the light-emitting part of the sign pole 417 may be made different between the case of non-cash payment in the service A operation mode (settlement processing for service A) and the case of non-cash payment in the service B operation mode (settlement processing for service B).
(7) The POS terminal 40 may illuminate the light-emitting portion of the sign pole 417 in a display manner that is distinct from the above when warning about a shortage of change (change near end, change near full) or a shortage of receipt paper (paper near end), etc.
(8) When a customer calls a store clerk, the POS terminal 40 may cause the light-emitting portion of the sign pole 417 to emit light in a display mode that is distinct from the above.

Regarding (1) to (8) above, as an example, the light-emitting part of the sign pole 417 may be controlled as follows.

When a store clerk is called, the top light-emitting unit 417a is lit in red. When the change is near full (the same may be true when the change is near full, and when the change is near full, it is not necessary to notify), the top light-emitting unit 417a is made to flash red quickly. When the paper is near full, the top light-emitting unit 417a is made to flash red slowly. When in service B standby mode, the middle light-emitting unit 417b is lit in green. When in common standby mode, the middle light-emitting unit 417b is made to flash. When in service A standby mode, the middle light-emitting unit 417b is turned off. When a product is being registered in service B operation mode, the lower light-emitting unit 417c is turned off. When a cash payment is being processed in service A operation mode (or service B operation mode), the lower light-emitting unit 417c is lit in yellow. When a non-cash payment is being processed in service A operation mode (or service B operation mode), the lower light-emitting unit 417c flashes yellow.

Note that, for the sake of simplicity, the above-mentioned specific example illustrates a case where each light-emitting element (light-emitting elements 417a, 417b, 417c) emits light in only one predetermined color (light-emitting element 417a emits light in only red, light-emitting element 417b emits light in only green, and light-emitting element 417c emits light in only yellow), but each light-emitting element can emit light in multiple colors (for example, light-emitting elements 417a, 417b, 417c can emit light in any of red, green, and yellow), and the notification content can be changed by changing the light-emitting color.

Although the embodiment of the present invention has been described above, the device configuration, data configuration, processing flow, display and output aspects, etc. can be modified as appropriate, for example, as in the modified examples below. In addition, the modified examples below may be combined as appropriate.

(1) In the above embodiment, it has been described that standby screen SG01, which is a common standby screen, is displayed after the process is completed (e.g., in place of the receipt screen). However, another screen may be displayed after the process is completed and may be displayed next to the other screen. For example, a power-saving screen (one example of another screen) may be displayed after the process is completed, and when the power-saving screen is touched (or when the human sensor reacts while the power-saving screen is displayed), the power-saving screen may switch to standby screen SG01. The same applies to the other common standby screens (standby screens SG11 to SG61) and the service A standby screen and service B standby screen.

(2) In the above embodiment, an example was described in which the settlement processing screen for service A and the settlement processing screen for service B are the same (common), but the settlement processing screen for service A and the settlement processing screen for service B may be different.

(3) In the above embodiment, an example was described in which the payment type (payment method) was selected after product registration was completed, but it may also be possible to select the payment type before completing product registration. In other words, in service A, customer A may be able to select the payment type before operating the Proceed to Checkout button BT604 (FIG. 3(D)), and in service B, customer B may be able to select the payment type before operating the Proceed to Checkout button BT414 (FIG. 9).

Specifically, in service A, the mobile terminal 60 may be able to accept a selection operation of a payment type from customer A while, for example, the start screen (FIG. 3(A)) is displayed, while the initial registration screen (FIG. 3(B)) before the registration of one product item is displayed, or while the registration screen (FIG. 3(D)) after the product is registered is displayed. In addition, in service B, the POS terminal 40 may be able to accept a selection operation of a payment type from customer B while, for example, the registration screen GM03 (FIG. 8) before the registration of one product item is displayed, or while the registration screen GM04 (FIG. 9) after the product is registered is displayed.

(4) In relation to (3) above, in service A, when the mobile terminal 60 receives a selection operation of a payment type from customer A while displaying the start screen (FIG. 3(A)), the initial registration screen before registering one product (FIG. 3(B)), or the registration screen after registering the product (FIG. 3(D)), the mobile terminal 60 may transmit information indicating the selected payment type (payment type selection information) to the cloud server 20. In addition, the POS terminal 40 (as well as the transaction status management device 50) may acquire the payment type selection information from the cloud server 20. Based on the payment type selection information, the transaction status management device 50 may determine whether the usage time of the POS terminal 40 by a certain customer A will be long (for example, if cash payment is selected, it may determine that the usage time will be long, and if non-cash payment is selected, it may determine that the usage time will be short), and may control the display of the signage according to the determination result. In this way, the signage can be used to notify other customers and store clerks that the usage time of a certain customer A may be long from the point before the customer completes product registration. In addition, by transmitting information about whether change is nearing end (such as which POS terminal 40 is nearing end of change) from the POS terminal 40 to the cloud server 20, when Customer A, who has selected cash payment, completes product registration, the information about whether change is nearing end can be provided, for example, on a two-dimensional code display screen (FIG. 3(E)).

(5) In relation to (3) above, in service B, when the POS terminal 40 receives a selection operation of a payment type from customer B while displaying the registration screen GM03 (FIG. 8) before the registration of one product item or the registration screen GM04 (FIG. 9) after the product registration, the POS terminal 40 may control the display of the sign pole 417 in response to the selection operation. This allows the sign pole 417 to be used to notify other customers and store clerks that customer B may be using the product for a long time before the product registration is completed by customer B. In addition, when the POS terminal 40 receives a selection operation of a payment type from customer B while displaying the registration screen GM03 (FIG. 8) before the registration of one product item or the registration screen GM04 (FIG. 9) after the product registration, the POS terminal 40 may transmit information indicating the selected payment type (payment type selection information) to the transaction status management device 50. The transaction status management device 50 may determine whether or not a certain customer B will be using the POS terminal 40 for a long time based on the payment type selection information, and control the display of the signage according to the result of the determination. This makes it possible to use the signage to notify other customers and store clerks that a certain customer B may be using the terminal for a long time even before the certain customer B completes product registration.

(6) In the above embodiment, the operation of the POS terminal 40 was described as an operation on the display unit 405 (touch display) (touching various buttons and areas arranged on the display unit 405). However, as described above, the POS terminal 40 may be provided with a key operation unit composed of various mechanical keys, and may be configured to accept operation of the mechanical keys instead of or in addition to operation on the display unit 405. For example, the POS terminal 40 may be configured to accept operation of a subtotal key as a mechanical key instead of or in addition to operation of the "Proceed to checkout button BT414" which corresponds to the subtotal button, or may be configured to accept operation of a deposit key as a mechanical key instead of or in addition to operation of the "End (receipt) button" which corresponds to the deposit button (current total button). The same applies to other buttons such as the store clerk call button BT403 and the language switching buttons BT405 to BT407. For each POS terminal 40, it may be possible to arbitrarily set whether each operation (e.g., subtotal operation, deposit operation, etc.) should be an operation on the display unit 405 (a button should be placed (displayed) on the display unit) or an operation on the key operation unit (a button should be placed (assigned) on the key operation unit). This allows appropriate settings to be made according to the usage situation, and if a problem occurs with one (poor response to operations due to deterioration over time or dirt, etc.), it is possible to switch to the other as appropriate.

(7) In the above embodiment, the common standby screen (standby screens GM01 to GM61), the service A standby screen, and the service B standby screen were described as standby screens, but other screens may be used for standby. For example, a member card reading instruction screen that instructs the user to read a member card may be used as the standby screen. The POS terminal 40 may execute various controls based on the member card read on the member card reading instruction screen.

For example, the POS terminal 40 may display a common screen (similar to the common standby screen, but referred to as the common screen because it is displayed after the member card reading instruction screen) when it determines based on the read member card that the customer is likely to be customer A, and may display a service B screen (similar to the service B standby screen, but referred to as the service B screen because it is displayed after the member card reading instruction screen) when it determines based on the read member card that the customer is not likely to be customer A. Note that, as a member card, when a member becomes a member who uses service B (a member who does not use service A), a general member card limited to use of service B is given, and when a member becomes a member who uses service A (a member who can also use service B), a special member card that allows use of service A in addition to service B is given (if a general member card has been given, it is collected or invalidated). In this way, the POS terminal 40 determines that the customer is likely to be customer A if the read member card is a special member card, and determines that the customer is not likely to be customer A if the read member card is a general member card. The general membership card and the special membership card may have the same (or nearly the same) appearance as the card medium, but the information stored therein (or the information associated with the information stored therein) may be different. Also, similar information may be stored in a mobile terminal (which may be mobile terminal 60) instead of a card.

In addition, in a device that does not support the A service (for example, a device dedicated to a full-self service that supports only the B service), if a special member card of a certain customer is read and the customer is an A customer, the customer (the A customer) will move to a device that supports the A service (for example, the POS terminal 40). In this case, when the movement is detected (for example, when absence is detected by a human sensor, etc.) (or when a predetermined time has passed since the movement was detected), the device that does not support the A service may erase the information read from the special member card and display the initial screen. Similarly, in a device that does not support the B service (for example, a device dedicated to a semi-self service that supports only the A service), if a general member card of a certain customer is read, the customer (the B customer) will move to a device that supports the B service (for example, the POS terminal 40). In this case, when the movement is detected (for example, when absence is detected by a human sensor, etc.) (or when a predetermined time has passed since the movement was detected), the device that does not support the B service may erase the information read from the general member card and display the initial screen. The timing for erasing the information read from the special membership card or the general membership card may be when the customer (presumably a different customer) is detected again, or when another membership card (special membership card, general membership card) is read.

(8) All or part of each function (input/output, storage, processing (including judgment)) in the POS terminal 40 in the above embodiment may be realized in another device different from the device described as the executing entity of the function. For example, as the processing of the POS terminal 40, at least part of the processing described using the flowchart of FIG. 10 may be executed by the store controller 10 or the cloud server 20 instead of the POS terminal 40. In relation to the above, the POS terminal 40 may function as a so-called thin client specialized for input/output interfaces, etc. For example, the POS terminal 40 may accept various inputs (customer operations, detection by a device such as a scanner) and transmit the input information (operation information, image information, etc.) to the cloud server 20, and then the cloud server 20 may execute processing according to the information received from the POS terminal 40 and transmit the processing result (update screen information, etc.) to the POS terminal 40, and then the POS terminal 40 may execute an operation (display on a display unit, etc.) according to the information received from the cloud server. In other words, the cloud server 20 may execute a program for controlling the operation of the POS terminal 40.

[Problem to be solved by the invention]
Although it is effective to introduce multiple systems into the same store to meet the needs of shoppers, introducing and operating multiple systems can cause various problems (e.g., operability, cost, etc.) The present invention has been made in view of such circumstances, and aims to provide a technique for solving various problems that arise when multiple systems are operating.
[Means for solving the problems]
(1) A product sales data processing device (e.g., a POS terminal 40) characterized by having a first processing mode (e.g., a service A operation mode) in which products registered on a portable registration terminal (e.g., a mobile terminal 60) are settled, a second processing mode (e.g., a service B operation mode) in which a customer registers and settles products on the product sales data processing device himself/herself, and a selection means (e.g., processing of steps S1 and S2 in Figure 10) for selecting either the first processing mode or the second processing mode.
The configuration (1) can solve various problems that arise when multiple systems (service A, service B) are in operation. For example, the product sales data processing device (e.g., the POS terminal 40) can handle multiple systems (service A, service B), which can prevent costs from increasing.
(2) A product sales data processing device as described in (1) is provided with a display means for displaying at least one of an operator for selecting the first processing mode (e.g., a self-checkout register selection button BT401) and an operator for selecting the second processing mode (e.g., a full-self-POS selection button BT402) (e.g., both are displayed on the standby screen GM01 of FIG. 4, the full-self-POS selection button BT402 is displayed on the standby screen GM21 of FIG. 12, and the self-checkout register selection button BT401 is displayed on the standby screen GM31 of FIG. 13), and the selection means selects either the first processing mode or the second processing mode based on the operation of the operator.
The configuration of (2) can solve various problems that arise when multiple systems (service A, service B) are in operation. For example, even a customer can easily select a desired system (service A, service B), and problems in operability are less likely to occur.
(3) A product sales data processing device as described in (1) is provided with a reading means for reading identification information, and the selection means selects the first processing mode when the reading means reads accounting identification information (e.g., a two-dimensional code 605 for settlement).
According to the configuration (3), the selection can be easily performed, and the selection can be performed without touching the screen.
(4) A product sales data processing device as described in (1) is provided with a display means for displaying at least one of an operator for selecting the first processing mode and an operator for selecting the second processing mode, and a reading means for reading identification information, wherein when the reading means reads identification information other than accounting identification information (for example, when a registration operation for a membership card or a gift certificate is performed), the display means displays both an operator for selecting the first processing mode and an operator for selecting the second processing mode, and the selection means selects either the first processing mode or the second processing mode based on the operation of the operator.
According to the configuration of (4), it is possible to reliably confirm which selection is made.
(5) The product sales data processing device described in (2) or (4) is characterized in that the display means displays a plurality of operators related to the second processing mode (e.g., the unnecessary button BT441 and the necessary button BT442 in Figures 15 and 16, etc.) instead of an operator for selecting the second processing mode.
According to the configuration (5), the second processing mode can be easily selected via an operator related to the second processing mode (without having to operate an operator for selecting the second processing mode).
(6) The product sales data processing device according to any one of (1) to (5), further comprising a notification means for notifying a result of the selection made by the selection means of the first processing mode or the second processing mode.
According to the configuration of (6), the selection result can be conveniently recognized, so that, for example, a store clerk or the like can recognize the processing mode that will be executed when a selection is made, and can grasp the processing mode that is being executed while the selection is being processed.
(7) A product sales data processing device (e.g., a POS terminal 40) comprising a first processing mode (e.g., a service A operation mode) in which products registered on a portable registration terminal (e.g., a mobile terminal 60) are settled, a second processing mode (e.g., a service B operation mode) in which a customer registers and settles products on the product sales data processing device himself, and a display means for displaying a possible standby screen (e.g., a common standby screen) for selecting either the first processing mode or the second processing mode, wherein when either the first processing mode or the second processing mode is operating and the other is not operating (e.g., outside the available hours of service A), the display means displays a dedicated standby screen (e.g., a service B standby screen) for either the first processing mode or the second processing mode that is operating, instead of the possible standby screen (common standby screen) for selecting either the first processing mode or the second processing mode.
According to the configuration of (7), various problems occurring when multiple systems (service A, service B) are in operation can be solved. For example, the product sales data processing device (e.g., POS terminal 40) can handle multiple systems (service A, service B), which can prevent increases in costs. In addition, a standby screen appropriate for the situation is displayed, making operation easier.
(8) A product sales data processing device having a registration means which a customer operates to register a product himself and a settlement means which the customer operates to settle the payment, the product sales data processing device having a first processing mode (e.g., service A operation mode) which is a processing mode in which the settlement means settles the payment for the product registered at a portable registration terminal, and a second processing mode (e.g., service B operation mode) which is a processing mode in which products are registered at the registration means and the settlement means settles the payment for the product registered at the registration means, and characterized in having a selection means (e.g., processing of steps S1 and S2 in Figure 10) which selects either the first processing mode or the second processing mode, and an execution means (e.g., processing of steps S5 and S6 in Figure 10) which executes processing according to the processing mode selected by the selection means. (e.g., processing of steps S5 and S6 in Figure 10).
According to the configuration (8), the same effect as that of (1) can be obtained.
(9) A program that causes a computer to function as a product sales data processing device, characterized in that the program causes the computer to function as a first processing mode in which products registered on a portable registration terminal are settled, a second processing mode in which a customer registers and settles for products on the product sales data processing device himself, and a selection means for selecting either the first processing mode or the second processing mode.
According to the configuration (9), the same effect as that of (1) can be obtained.

In addition, a program for implementing the functions of each device described above (POS terminal 40, transaction status management device 50, mobile terminal 60, etc.) may be recorded on a computer-readable recording medium, and the program recorded on the recording medium may be read into a computer system and executed to process each device. Here, "reading a program recorded on a recording medium into a computer system and executing it" includes installing the program into a computer system. The "computer system" here includes hardware such as an OS and peripheral devices. In addition, the "computer system" may include multiple computer devices connected via a network including the Internet, WAN, LAN, dedicated lines, and other communication lines. In addition, the "computer-readable recording medium" refers to portable media such as flexible disks, optical magnetic disks, ROMs, and CD-ROMs, and storage devices such as hard disks built into a computer system. In this way, the recording medium storing the program may be a non-transient recording medium such as a CD-ROM. In addition, the recording medium also includes a recording medium provided inside or outside and accessible from a distribution server to distribute the program. The code of the program stored in the recording medium of the distribution server may be different from the code of the program in a format executable by the terminal device. In other words, as long as it can be downloaded from the distribution server and installed in a format executable by the terminal device, the format in which it is stored in the distribution server does not matter. The program may be divided into multiple parts, downloaded at different times, and then combined on the terminal device, or each of the divided programs may be distributed by a different distribution server. Furthermore, the "computer-readable recording medium" includes a memory that holds a program for a certain period of time, such as a volatile memory (RAM) inside a computer system that becomes a server or client when a program is transmitted over a network. The program may also be a program for realizing part of the above-mentioned functions. Furthermore, the program may be a so-called difference file (difference program) that can realize the above-mentioned functions in combination with a program already recorded in the computer system.
