A reader device for radio frequency identification transponders, which implements enhanced radio frequency identification transponder functionality. The reader device is capable of serving as a radio frequency identification transponder. Such a reader device includes a reader logic unit, a radio/high frequency (RF/HF) interface and an antenna, and is adapted to communicate at least with radio frequency identification transponders in a reader operation mode. The reader device also includes a transponder logic unit that is connected to the reader device and in particular to the radio/high frequency (RF/HF) interface such that the reader device acts as a radio frequency identification transponder in a transponder operation mode. In particular, the transponder logic unit is adapted to communicate with other reader devices for radio frequency identification transponders. The reader device for radio frequency identification transponders can be attached, connected, implemented and/or embedded in electronic device and particularly portable electronic devices, respectively.

1. A near-field communication (NFC) apparatus configured to be hosted by an electronic device, the NFC apparatus comprising: a reader portion connectable to a radio frequency interface and configured to cause the NFC apparatus to operate in a reader operation mode to detect and communicate with radio frequency identification transponders and radio frequency identification readers;a transponder portion connectable to the radio frequency interface and configured to cause the NFC apparatus to operate in a show communication mode to act as a passive radio frequency identification transponder; anda switching unit configured to switch the NFC apparatus operation between the reader operation mode and the show communication mode,wherein when the NFC apparatus is receiving power from the electronic device the switching unit switches the NFC apparatus to the reader operation mode, andwherein when the NFC apparatus is not receiving power from the electronic device the switching unit switches the NFC apparatus to the show communication mode. 2. The NFC apparatus of claim 1, wherein the electronic device is powered on during a time when the NFC apparatus is not receiving power from the electronic device. 3. The NFC apparatus according to claim 1, wherein the show communication mode is operable independently from a power supply of the electronic device, and wherein the transponder portion is energized by an interrogating signal. 4. The NFC apparatus according to claim 1, wherein the NFC apparatus acts as a passive read-only radio frequency identification transponder in the show communication mode. 5. The NFC apparatus according to claim 1, wherein the transponder portion comprises a transponder memory. 6. The NFC apparatus according to claim 5, wherein the transponder memory is non-volatile. 7. The NFC apparatus according to claim 5, wherein the transponder memory is configurable. 8. The NFC apparatus according to claim 1, wherein the transponder portion is coupled through the switching unit to the radio frequency interface. 9. The NFC apparatus according to claim 1, wherein the NFC apparatus operates autonomously in the show communication mode during periods of time, within which the NFC apparatus is not energized from a power supply of the electronic device. 10. The NFC apparatus according to claim 1, wherein the radio frequency interface is adapted to provide signals required for operation of the NFC apparatus in the reader operation mode and the show communication mode. 11. The NFC apparatus according to claim 1, wherein the NFC apparatus supports near field communication (ECMA-340) standard, and wherein the NFC apparatus is operable with a passive communication mode in the reader operation mode. 12. The NFC apparatus according to claim 11, wherein the NFC apparatus is operable with an active communication mode in the reader operation mode. 13. The NFC apparatus according to claim 1, wherein the electronic device comprises a portable terminal. 14. The NFC apparatus according to claim 6, wherein the transponder memory is configurable. 15. The NFC apparatus according to claim 13, wherein the portable terminal is enabled to communicate via a public land mobile network. 16. A method comprising: causing a near-field communication (NFC) apparatus configured to be hosted by an electronic device to operate, via a reader portion, in a reader operation mode to detect and communicate with radio frequency identification transponders and radio frequency identification readers;causing the NFC apparatus to operate, via a transponder portion, in a show communication mode to act as a passive radio frequency identification transponder; andswitching the NFC apparatus between the reader operation mode and the show communication mode,wherein when the NFC apparatus is receiving power from the electronic device causing switching of the NFC apparatus to the reader operation mode, andwherein when the NFC apparatus is not receiving power from the electronic device causing switching of the NFC apparatus to the show communication mode. 17. The method according to claim 16, wherein the electronic device is powered on during a time when the NFC apparatus is not receiving power from the electronic device. 18. The method according to claim 16, wherein the show communication mode is operable independently from a power supply of the electronic device, and wherein the transponder portion is energized by an interrogating signal. 19. The method according to claim 16, further comprising causing the NFC apparatus to act as a passive read-only radio frequency identification transponder in the show communication mode. 20. The method according to claim 16, further comprising causing the NFC apparatus to operate autonomously in the show communication mode during periods of time, within which the NFC apparatus is not energized from a power supply of the electronic device. 21. The method according to claim 16, further comprising providing signals required for operation of the NFC apparatus in the reader operation mode and the show communication mode via a common radio frequency interface. 22. The method according to claim 16, wherein the NFC apparatus supports near field communication (ECMA-340) standard, and wherein the NFC apparatus is operable with a passive communication mode in the reader operation mode. 23. The method according to claim 22, wherein the NFC apparatus is operable with an active communication mode in the reader operation mode.
