Nfc Communicators and Nfc Communications Enabled Devices
First Claim
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.

Abstract
A NFC communicator or NFC communications enabled device (1 or 2 or 100a) has a data store (108) to store data, a coupler (17 or 32 or 102) to couple inductively with the magnetic field of a radio frequency signal and a signal generator (109) to supply a radio frequency signal to the coupler. A modulator (110) is provided to modulate a radio frequency signal in accordance with data and a demodulator (114) is provided to extract data from a modulated radio frequency signal inductively coupled to the coupler. A controller (107) 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 deliver (19 or 34 or 103) that derives power from a radio frequency signal inductively coupled to the coupler to charge a chargeable power supply.
