Abstract
A communications device has a NFC communicator (15) having a coupler (17) to couple with a coupler of a near field RF communicator in near field range to enable communication of data between the communicators by modulation of a magnetic field, a demodulator (42) to extract modulation from a modulated signal coupled to the coupler and a modulator (40) to modulate an RF signal in accordance with data to be communicated by the NFC communicator. The device also has at least one secure element (30; 31) separate from the near field RF communicator (15) to provide secure data storage for transaction data representing or relating to a transaction. A controller controls operation of the NFC communicator, reads transaction data from the at least one secure element and causes the modulator to modulate an RF signal in accordance with transaction data read from the at least one secure element so as to communicate the read transaction data to a near field RF communicator in near field range as proof of the transaction to enable an action related to the transaction to be carried out.
