摘要： A data transmission system for the non-contact transmission of data between a station (1) and a portable data carrier (2). The station (1) includes a station transmitter (3) operating at a predetermined frequency for generating a first signal and a demodulator (35) for detecting a second signal superimposed on the first signal. An antenna (5) is coupled via a length of cable (4) to the station transmitter (3) via a matching circuit (6) so as to be operative at said frequency regardless of the length of the cable (4). The portable data carrier (2) includes supply means (13) for coupling to a source of electric power and a data carrier tuned antenna circuit (10, 55) inductively coupled with the station transmitter (3) so as to receive power from the station (1). A data carrier data modulator (14) is provided for modulating the first signal with the second signal in response to data stored within the data carrier (2) and, by means of said inductive coupling, enabling the data to be transmitted from the data carrier (2) to the station (1).

摘要： A multi-application contactless smart card system and method. The user may select application using selection mechanism located on the smart card or at the contactless reader. The selection means may be connected to the contact I/O pin of the processor of the smart card. In some embodiments, the processor of the smart card may read the user selection through the contact I/O pin during a simulated contact transaction, evoke the desired application and perform the contactless transaction. During the simulated contact transaction power up sequence is preserved by extracting power signals to the contact V DD pin from the RF signal. Alternatively, the state of the selection mechanism may be sampled continuously or at convenient time intervals, enabling further switching between applications during a single contactless session.
