  • smart card readers are physically connected to, and intimately associated with, a service-providing apparatus.
  • a service-providing apparatus One example is a computer.
  • a user seeking access to the computer has the user's smart card read by the smart card reader, and information derived from the smart card is then analyzed. The analysis is basically a security check. When the computer determines that the user is authorized, access is granted to the computer's resources.
  • Another application of smart cards is to provide a value, such as a dollar amount.
  • the card is read by a smart card reader that is coupled to a computing means in association with a service-providing device; and with each use the dollar amount associated with the card is decremented.
  • An apparatus for interfacing a smart card with a telecommunications network using a conventional plain old telephone set.
  • the apparatus includes a line interface unit having a first port, a second port, and a third port.
  • the first port is adapted for coupling to a telephone network

  • the third port is adapted for l s coupling to a smart card microprocessor via a smart card reader.

  • FIG. 2 depicts the adjunct of FIG. 1 with an RF module connected thereto to create a wireless apparatus
  • FIG. 3 presents another embodiment of a telephone-smart card reader adjunct in accordance with the principles of this invention.
  • Fig. 1 describes one embodiment of an apparatus employing the principles of this invention. It comprises smart card reader 10 and a line interface unit 20. Unit 20 is connected to smart card reader 10 and to ports 25 and 30. Port 25 is adapted for connection to the telephone network, and port 30 is adapted for connection to a telephone instrument or the like (e.g., a modem).
  • Smart card reader 10 is a conventional smart card reader, not unlike the smart card reader sold by AT&T under the name "AT&T Smartcard Reader - 5B".
  • This device contains mechanical means for coupling a smart card to the reader, and electronic circuitry. The latter includes circuitry for coupling power to the smart card reader, and circuitry for communicating digital information to and from the smart card. This digital information may include any combination of data signals and/or control signals.
  • control signals are used to specify the performance of particular instructions by a hardware device equipped to respond to such instructions as, for example, a microprocessor.
  • Data signals are used to represent analog quantities, characters, facts, and/or concepts to which some meaning may be assigned.
  • the above-referenced reader also includes a microprocessor but, for purposes of this invention, the microprocessor is not required.
  • FIG. 1 apparatus is first described for a digital environment and then described for an analog environment. Thereafter, the description proceeds solely in the analog environment, but it is to be understood that a digital environment is within the contemplation of this invention.
  • port 25 may be adapted to work in a digital telephone network such as the ISDN network, where signals may flow in frames of 128 bits that contain 16 control bits.
  • port 30 would also be adapted to work digitally and the telephone instrument connected to port 30 would be one that is adapted to receive such 128-bit frames.
  • the FIG. 1 apparatus is first described for a digital environment and then described for an analog environment. Thereafter, the description proceeds solely in the analog environment, but it is to be understood that a digital environment is within the contemplation of this invention.
  • port 25 may be adapted to work in a digital telephone network such as the ISDN network, where signals may flow in frames of 128 bits that contain 16 control bits.

  • Control of switch 22 is effected via signalling on ports 25 and 30, and/or reader 10. More specifically, controller 23 is responsive to the signals arriving from ports 25 and 30, and arriving from reader interface unit 24. The state of switch 22 is dictated by the control signals detected by controller 23 from reader 10 and from ports 25 and 30.
  • the primary signal conversion need is the need to convert the digital signals developed by the smart card reader into analog form and, conversely, to convert analog signals destined to the smart card reader into digital format.
  • This function is performed by the modem.
  • switch 22 is not required for proper operation ofthe FIG. 1 apparatus because low-level analog noise signals emanating from port 30 can be ignored in a properly designed reader 10. More specifically, in a "poor-man's" embodiment of this invention, it is possible to do without switch 22, and merely instruct the user to not speak during data transmission to and from reader 10. Of course, it is beneficial to include a switch 22 and a switch controller 23 so that the signals of port 30 can be blocked when appropriate.
  • Controller 23 can control switch 22 in myriad ways.
  • One way, for example, is to give ultimate control to port 30.
  • POTS telephone plain old telephone set
  • the user who is connected to the FIG. 1 apparatus via a plain old telephone set (POTS telephone) coupled to port 30, can then have ultimate control over the operation ofthe FIG. 1 apparatus.
  • POTS telephone could, but need not, be a touch-tone telephone.
  • Such control is effected, for example, through a touch-tone pad at the user's telephone instrument.
  • ultimate control can be given to port 25, so that whenever the apparatus that is connected to port 25 via the telephone network wishes to request digital information from reader 10, or to send digital information to reader 10, it can do so regardless of whether or not the user is engaged in a conversation with the called party (or with a nearby listener who is not really part ofthe telephone connection).
  • Ultimate control can be granted to port 25 simply by including a means, connected to port 25, for detecting a carrier signal. Such means may comprise conventional circuits for "carrier detect", which are found in all dial modems. When a carrier is detected, the connection between ports 25 and 30 is disabled, and the telephone at port 30 is effectively muted.
  • control can also be established by the signals arriving from reader 10, in a manner not unlike the manner by which control is granted to port 25.
  • switch 22 is depicted above as a single pole-double throw switch that connects port 25 to either port 30 or to reader 10, that need not be the case. It is very easy to employ a switch 22 that also permits port 30 to be connected to reader 10, or even a sli ⁇ htly more complex switch that connects port 25 to a "hold" circuit 25 when port 30 is connected to reader 10.
  • FIG. 1 shows terminating circuit 26 connected to switch 22.
  • the combination realized with a conventional telephone coupled to the FIG. 1 adjunct is a very "smart" phone, because the smart card imparts all of its capabilities to the combination. Many advantabes can result from such a combination, including, for example, a very beneficial wireless phone (e.g., a cellular phone). All that is required to create a wireless phone is an RF receiver and transmitter section that is coupled to port 25. This is depicted in FIG. 2.
  • the advantage of the FIG. 2 wireless phone is that all personalized information is contained in the smart card, and not in the phone. That means that a user can pick ⁇ up any telephone arrangement that includes the adjuncts (of course, the functions of a conventional telephone can be inco ⁇ orated in the FIG. 1 apparatus, yielding a phone with a smart card reader) and convert it to a uniquely personal cellular telephone simply by inserting the user's smart card into it. This benefit, by the way, accrues to the FIG. 1 arrangements as well.
  • a display means To further enhance operation ofthe FIG. 1 apparatus, it is useful to include a display means.
  • the intent is to display some ofthe information that is entered into, that is delivered by, reader 10.
  • a display may be connected to switch 22 to allow data that flows to and from reader 10 to be captured at appropriate times and be displayed.
  • a conventional touch-tone telephone provides limited capability for the user to supply character information to either reader 10 or to port 25.
  • a user will be requesting service from a representative of a service provider.
  • the service provider may wish to authenticate not only the user but also the identity ofthe representative (such as when the representative is a traveling salesperson).
  • an adjunct that includes two smart card readers. With two readers, it is possible to arrange for the service to be provided only when the information read from both readers is correct.
  • the second reader may be inco ⁇ orated into the structure ofthe adjunct, or it may be connected through a separate port in the same manner that reader 10 is connected to the line interface unit of FIG. 1.
  • FIG. 3 An arrangement that includes all ofthe above enhancements is depicted in FIG. 3. It should be understood, of course, that any particular embodiment employing the principles of this invention need not use all of these enhancements. Any combination can be employed.
  • microprocessor 31 is connected to switch 22 and to ports 25 and 30.
  • Memory 32 is connected to microprocessor 31.
  • Keyboard 33 is connected to switch 22
  • display means 34 is connected to switch 22
  • reader 35 is connected to switch 22 via reader interface unit 36. All of those elements are also connected to controller 23, allowing switch 22 to effect whatever connection patterns the designer wishes to implement.
  • Switch 22 for the FIG. 3 embodiments can be an electronic crossbar switch, but it doesn't need to be a "full access" switch because certain connections are not likely to ever be used. For example, no element other than port 25 will ever be connected to termination circuit 26.
  • interface 40 may simply comprise a router. It accepts signals in one ofthe three formats and directs those signals to the appropriate outputs based on specified criteria.
  • interface 40 may include circuitry that differentiates between voice signals, modem signal data and touch- tone data. Such a capability is easily achievable with conventional circuitry. The circuitry must only be sensitive to whether the signal is touch-tone or a modulated modem signal. All such circuits are available in the industry. Signals which are neither touch-tone nor modem can be concluded to be voice signals.
  • Telephone system 60 can be an ACD, which in turn is connected to service agents.
  • the AT&T CONVERSANT Voice Information System equipped with ARS (Automatic Speech Recognition) and T-T-S (Text-to-Speech) is also capable of creating computer-generated voice responses. Some such systems create the voice responses that correspond to pre-recorded messages and others generate voice from text, "on-the-fly".
  • CONVERSANT Voice Information System equipped with ASR (Automatic Speech Recognition) and T-T-S (Text-to-Speech) has the ability to recognize speech by recognizing certain words in the stream of spoken words and respond accordingly.
