1. A near-field communication (NFC) system comprising:

  • a plurality of NFC devices each comprisingan NFC circuit configured to wirelessly communicate using an NFC communications protocol, anda processor coupled to said NFC circuit and the processor being configured to;

    synchronize an internal timing signal to an external timing signal,cycle power to said NFC circuit to periodically switch the NFC circuit between a peer-to-peer recognition state and a low power state based upon the synchronized internal timing signal, andinitiate peer-to-peer NFC communications with another one of said plurality of NFC devices when in range thereof and upon being switched to the peer-to-peer recognition state therewith.
