Abstract:
    The multiple access scheme for RF card comprises: the RF mark generates Gold sequence with some length set by Interrogator; when taking two-phase key control or amplitude key-control to UHF of reading device, using the Gold sequence to modulate and transmit the Tag; on receiving terminal, taking correlation calculation to decide existence of some Tag for RF recognition.
