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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Extended functionality of RFID devices","description":"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.
