Reader device for radio frequency identification transponder with transponder functionality
First Claim
1. A reader device comprising:
- a power supply configured to power the reader device;
a reader logic unit connectable to a radio frequency interface and configured to cause the reader device to operate in a reader operation mode by transmitting interrogation signals to detect and communicate with radio frequency identification transponders and by simulating an active radio frequency identification tag to communicate with another radio frequency identification reader;
a transponder logic unit which is connectable to the radio frequency interface, wherein the transponder logic unit is configured to cause the reader device to operate in a show communication mode wherein the reader device acts as a passive radio frequency identification transponder; and
a switching unit configured to automatically switch the reader device between the reader operation mode and the show communication mode,wherein when the reader device is receiving power from the power supply the switching unit automatically switches the reader device to the reader operation mode, andwherein when the reader device is not receiving power from the power supply the switching unit automatically switches the reader device 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.

15. A method comprising:
-
causing a reader device to operate, via a reader logic unit, in a reader operation mode by transmitting interrogation signals to detect and communicate with radio frequency identification transponders and by simulating an active radio frequency identification tag to communicate with another radio frequency identification reader; causing the reader device to operate, via a transponder logic unit, in a show communication mode wherein the reader device acts as a passive radio frequency identification transponder; and switching automatically, the reader device between the reader operation mode and the show communication mode, wherein when the reader device is receiving power from a reader device power supply causing the automatic switching to automatically switch the reader device to the reader operation mode, and wherein when the reader device is not receiving power from the reader device power supply causing the automatic switching to automatically switch the reader device to the show communication mode. - View Dependent Claims (16, 17, 18, 19, 20, 21)
