A radio frequency identification (RFID) device is arranged for use with a remote interrogator unit. The RFID device comprises an integrated circuit configured to send, in response to a signal received from the remote interrogator unit or automatically, a responsive signal which includes identification information. A communication antenna is electrically coupled to the integrated circuit and is provided for wireless communication with the remote interrogator unit. At least one photovoltaic cell is provided for converting radiation into electrical energy and providing power to the integrated circuit. The photocell may be designed to form all or part of the RF antenna of the RFID device.
