1. An NFC communicator, comprising:

  • a data store operable to store data;

    a coupler operable to couple inductively with the magnetic field of a radio frequency signal;

    a signal generator operable to supply a radio frequency signal to the coupler;

    a modulator operable to modulate a radio frequency signal in accordance with data;

    a demodulator operable to extract data from a modulated radio frequency signal inductively coupled to the coupler;

    a controller operable to enable the NFC communicator both to initiate near field radio frequency communication with another near field RF communicator and to respond to near field radio frequency communication initiated by another near field RF communicator; and

    a power deriver operable to derive power from a radio frequency signal inductively coupled to the coupler to charge a chargeable power supply.
