EXTENDED FUNCTIONALITY OF RFID DEVICES
First Claim
1. A RFID device comprisinga data memory (236),an electronic circuit arrangement (237, 238, 239, 247), which is coupled to the data memory (236),the electronic circuit arrangement (237, 238, 239, 247) having a first operational configuration and a second operational configuration, whereinby receiving a control command (250a) the electronic circuit arrangement (237, 238, 239, 247) can be switched irreversibly from the first operational configuration to the second operational configuration, anda communication interface (245), which is coupled to the electronic circuit arrangement (237, 238, 239, 247),whereinin the first operational configuration the RFID device (231a, 231b, 231c, 331) is adapted to communicate with a standard RFID reader (110) via the communication interface (245), andin the second operational configuration the communication with the standard RFID reader (110) is disabled and the RFID device (231a, 231b, 231c, 331) is adapted to communicate with a readout-RFID device (370).

Abstract
It is described a RFID device (231a, 231b, 231c, 331) comprising a data memory (236) and an electronic circuit arrangement (237, 238, 239, 247) coupled thereto. The electronic circuit arrangement has a first and a second operational configuration, wherein by receiving a control command (250a) the electronic circuit arrangement can be switched irreversibly from the first to the second configuration. The RFID device further comprises a communication interface (245) being coupled to the electronic circuit arrangement. In the first configuration the RFID device is adapted to communicate with a standard RFID reader (110) via the communication interface. In the second configuration the communication with the standard RFID reader is disabled and the RFID device is adapted to communicate with a readout-RFID device (370). The RFID device may be equipped with a secondary communication interface that can be used to communicate with the RFID device in a privacy-preserving manner. After the RFID device has been disabled, the secondary interface can be used to access data in a secure manner.
