Abstract: A transaction device is described. The device comprises storage configured to store a first data record comprising first value data and a unique identifier associated with one other device; communications circuitry configured to receive an identifier and second value data from a device; and control circuitry configured to compare the received identifier with the unique identifier and in the event of a positive comparison, the control circuitry is further configured to update the stored first value data in accordance with the exchanged second value data.
