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).

61. 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, an instruction to transmit first RFID transponder data; 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 RFID transponder data by the transceiver as an RFID transponder signal. - View Dependent Claims (62, 63, 64, 65, 66, 67)

68. A method for providing a radio frequency identifier (RFID), from a switchable mobile communications device capable of RFID communication and voice call communication, the method comprising:
-
monitoring, by the mobile communication device, for proximal presence of a proximal RFID reader, the mobile communication device having a transceiver configured, to output, in a first state, RFID transponder data to be received by the proximal RFID reader upon the mobile communications device determining proximal presence of one or more RFID readers, the transceiver being also configured to output, in a second state, a voice call signal for transmission at least in part over a wireless network; and on detection of the RFID reader, outputting, by the transceiver, the RFID transponder data as a radio frequency signal. - View Dependent Claims (69, 70, 71)

72. A switchable mobile communication device capable of RFID communication and voice call communication, the mobile communication device comprising:
-
a transmitter configured to transmit a radio frequency signal, the transmitter comprising a first signal processing section and a second signal processing section, the first signal processing section configured to output voice call signals in a first radio frequency range and the second signal processing section configured to output RFID transponder signals in a second radio frequency range; a storage medium to store a first data and instructions to; monitor for proximal presence of one or more RFID readers; and operate the transmitter to switch between the first and second signal processing sections to selectively;
(a) output first RFID transponder data as said RFID transponder signals in response to detection by the mobile communication device of the proximal RFID reader, and (b) output a voice call signal for transmission over a wireless network; anda processor coupled to the transmitter and the storage to execute the instructions. - View Dependent Claims (73, 74, 75, 76, 77, 78, 79)
