1. An RFID tag including:
- a substrate;
an RFID integrated circuit secured to said substrate;
an RFID antenna also secured to said substrate; and
wherein said tag is arrangeable in a first configuration in which said integrated circuit and said antenna are operatively electrically coupled to provide an RFID function, and a second configuration in which electric coupling of said antenna and circuit is altered to change said function, with said tag being alterable from said first configuration to said second configuration, and from said second configuration to said first configuration to at least partly reverse said change to said function, wherein said tag includes an adhesive to retain the tag in the first configuration, and wherein the adhesive is releasable to allow the tag to be rearranged from the first configuration to the second configuration and re-attachable to allow the tag to again be retained in the first configuration after being rearranged from the first configuration to the second configuration.

Abstract
An RFID tag that is foldable about a generally transverse fold line. The line divides the tag into two regions. One region has an RFID integrated circuit and areas of electrically conductive material. The other region has conductive areas that provide an efficient RFID antenna. In a folded configuration the areas are operatively associated with the integrated circuit while in the open configuration the areas are not functionally associated with the integrated circuit. Accordingly in the open configuration the tag is disabled or its RFID performance substantially degraded. The tag can be reversibly altered between the open and folded configurations.
