An RFID tag (100) that is foldable about a generally transverse fold line (101). The line (101) divides the tag (100) into regions 1 and 2. The regio n 1 has an RFID integrated circuit (104) and areas (105) of electrically con ductive material. The region 2 has conductive areas (107) that provide an ef ficient RFID antenna. In a folded configuration the areas (107) are operativ ely associated with the integrated circuit (104) while in the open configura tion the areas (107) are not functionally associated with the integrated cir cuit (104). Accordingly in the open configuration the tag (100) is disabled or its RFID performance substantially degraded. The tag (100) can be reversi bly altered between the open and folded configurations.
