SYSTEM AND METHOD FOR COUPLING PROXIMITY IC CARD/MODULE TO PROXIMITY COUPLING DEVICE IN LOW MUTUAL MAGNETIC COUPLING CONDITIONS

摘要

A proximity integrated circuit card (PICC) is disclosed comprising a main loop antenna to transmit data from said PICC and a secondary loop antenna to receive RF transmission to said PICC. The main antenna and the secondary antenna arranged to yield low mutual magnetic coupling so that the RF transmission to the PICC yields bigger signal in the secondary antenna than the signal that yields in the secondary antenna from a transmission from the main antenna. According to some embodiments the secondary antenna is arranged to only partially overlap said main antenna.
