Reader device for radio frequency identification transponder with transponder functionality
First Claim
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; and
a 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.

Abstract
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.
