Abstract
A NFC communicator or NFC communications enabled device has a data store to store data, a coupler to couple inductively with the magnetic field of a radio frequency signal and a signal generator to supply a radio frequency signal to the coupler. A modulator is provided to modulate a radio frequency signal in accordance with data and a demodulator is provided to extract data from a modulated radio frequency signal inductively coupled to the coupler. A controller enables the NFC communicator or NFC communications enabled device 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. The NFC communicator or NFC communications enabled device also has a power deriver that derives power from a radio frequency signal inductively coupled to the coupler to charge a chargeable power supply.
