A mobile communications device is described which includes an input senso r, a memory unit, processing unit, and an antenna configured to wirelessly t ransmit and receive financial account data for a transaction. The antenna is configured to receive a request for data stored on the memory unit, and may also be configured to induce a voltage from a magnetic field to power certa in components of the device. The input sensor may control whether the compon ents can be so powered from the magnetic field. Alternatively, input from th e input sensor may otherwise control the functionality of the device. By way of example, data representative of an input received by the input sensor ma y be transmitted in addition to the requested data. |
