1. A first device for use in establishing a contactless communications link with a second device, the first device comprising:

  • a full-duplex transceiver system comprising;

    first contactless communications circuitry (CCC) configured for transmitting data via a first contactless communications link to the second device; and

    second contactless communications circuitry (CCC) configured for receiving data via a second contactless communications link from the second device; and

    a data bus coupled to provide data signals to and receive data signals from the full-duplex transceiver system,wherein the first CCC comprises a first state machine that is operative to track protocol states of the first CCC, and wherein the second CCC comprises a second state machine that is operative to track protocol states of the second CCC.
