摘要
Communication interface card (20) is inserted within a reader (10) that has a resistive or capacitive interface based on coupling contacts (24). The card also has electromagnetic transmitter receiver (26) that communicates with a similar device (34) in a portable object. The interface card includes an element (28) for managing data transfer between its electrical contacts and its antenna.
