Communications devices comprising NFC communicators
First Claim
1. A communications device, comprising:
- an NFC communicator having a first coupler configured to couple with a second 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 configured to extract modulation from a modulated signal coupled to the first coupler;
a modulator configured to modulate an RF signal in accordance with data to be communicated by the NFC communicator;
at least one secure element, having a plurality of memory areas with differing levels of access, configured to provide secure data storage for transaction data relating to a transaction, wherein the differing levels of access relate to at least one of a read access and an edit access of the memory areas by a user; and
a controller configured to control operation of the NFC communicator, to read transaction data from the at least one secure element, and to cause the modulator to modulate the 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 second 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.

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.

29. A communications device, comprising:
-
NFC communication means having a first coupling means for coupling with a second coupling means of a near field RF communication means in near field range to enable communication of data between the communication means by modulation of a magnetic field; demodulation means for extracting modulation from a modulated signal coupled to the first coupling means; modulation means for modulating an RF signal in accordance with data to be communicated by the NFC communication means; secure element means for providing secure data storage for transaction data representing or relating to a transaction, wherein the secure element means includes differing levels of access that relate to at least one of a read access and an edit access of the secure element means by a user; and control means for controlling operation of the NFC communication means, for reading the transaction data from the secure element means and for causing the modulation means to modulate the RF signal in accordance with the transaction data read from the secure element means so as to communicate the read transaction data to a second near field RF communication means in near field range as proof of the transaction to enable an action related to the transaction to be carried out.
