ABSTRACT:
Embodiments enable controlling a proximity transaction between first and second communications devices, each of which is provided with a short-range transceiver. In an exemplary embodiment, the first communications device has an RF/ID reader, and the second communications device has an RF/ID tag, the RF/ID tag containing the same identifier information as the second communications device. The second communications device is positioned within the range of the reader of the first communications device. Then, the transceiver of the second communications device transmits a transaction request and the identifies information of that device to the first communications device. The reader of the first communications device then interrogates the tag of the second communications device and the transaction is completed upon the reader of the first communications device receiving identifier information from the tag of the second communications device that is identical to the identifier information already received.
