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).
Claims39
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.
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 for proximal presence of a proximal RFID reader external to said mobile communication device by said mobile communication device, the mobile communication device having a transceiver configured, to output, in a first state, RFID transponder data in a format compatible with said 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, said data being output in said format employed by the RFID reader.
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 external to the mobile communication device;
- 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 a format employed by a proximal RFID reader, 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;
- and
- a processor coupled to the transmitter and the storage to execute the instructions.
A switchable mobile communication device capable of radio frequency identifier RFID communication and voice call communication, the mobile communication device comprising:
- a transmitter configured to transmit a voice call signal in a first operational state and a RFID transponder signal in a second operational state;
- a storage medium to store a first data and instructions to switch the transmitter between the first and second operational states to selectively (a) monitor for proximal presence of a proximal RFID reader, and on detection of the proximal RFID reader, output RFID transponder data as an RFID signal in a format employed by the RFID reader, and (b) transmit a voice call signal to another user of another communication device at least in part over a wireless network;
- and
- a processor coupled to the transmitter and the storage to execute the instructions.
