Definitions
- the invention relates to a method for arranging coils for contactless smart cards (smart cards), which contain coils 9, 10 for electromagnetic coupling of the cards with their environment.
- Coil arrangements are described which multiply the coil effect of a coil on a carrier element by superimposing carrier elements.
- the thickness of the card is used to increase the coil effect. In this way, cards can receive more power from a transmitter in a small space. Data can be transmitted over a greater distance.
