Abstract

An RFID tag assembly for attachment to an enclosure surface including a door, an RFID tag attached to one face of the door or wrapped around the door, and an attachment device for connecting the door to the enclosure surface to allow the door to move to a position that shows both sides of the door. The RFID tag can include a ground plane, the tag wrapped around the door such that the ground plane is on the back of the door and the RFID tag antenna is on the front of the door. A ground plane can be provided on the enclosure inner or outer surface in alignment with the RFID tag antenna, with the antenna directly or inductively coupled to the ground plane when the door is in a closed position.
