Abstract
A communications device configured to couple with a near field RF communicator, in near field range, to enable communication of data by modulation of a magnetic field. The communications device also including a secure element, having a plurality of memory areas with differing levels of access, configured to provide secure data storage for transaction data, wherein the levels of access are differentiated by a degree to which the plurality of memory areas are programmable, writable and modifiable. Further, the communications device includes a controller configured to read the transaction data from the at least one secure element, and to cause a modulator to modulate the RF signal in accordance with transaction data read from the secure element so as to communicate the read transaction data to the near field RF communicator as proof of the transaction to enable an action related to the transaction to be carried out.
