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.
