Emulated radio frequency identification
DCFirst Claim
1. A method for providing a radio frequency identification (RFID) from a switchable mobile communications device capable of RFID communication and voice call communication, the method comprising:
- receiving, by the mobile communications device, from an RFID reader external to the mobile device, an instruction to transmit first RFID transponder data in a format compatible with said RFID reader;
switching a transceiver of the mobile communications device from a first state to a second state upon reception of said instruction, the transceiver configured to output voice call signals in the first state and to output RFID transponder signals in the second state; and
outputting the first data by the transceiver in the second state, the transceiver outputting the first data as an RFID transponder signal in the format compatible with said RFID reader.

Abstract
A mobile communication device is equipped with hardware and/or software components to enable the device to output a data in a form of a radio frequency signal, emulating outputting of the data by either an active or a passive RFID transponder. The data may be a security key or an identifier. Emulation of an active RFID transponder includes facilitating selection of the data and instruction to output by a user. Emulation of a passive RFID transponder includes detecting for proximal presence of a RFID reader. Either case, provision of the data to the mobile communication device may include provision of associated signal attribute(s).
