Abstract

The present invention provides for an electronic label associated with a transponder. The electronic label displays at least one graphical element to provide a visual indication representative of information associated with the transponder. Representable information can include a result of a communication with the transponder, a location of the transponder or an item associated with the transponder, a state of the transponder, or an item associated with the transponder, a status of the transponder or an item associated with the transponder, or any combination of information. The display of the graphical element can further indicate if a read operation has failed or has not yet taken place. The graphical element is alterable and updateable. The graphical element can indicate if the RFID tag is activate or has been deactivated allowing a consumer to readily determine the state of an RFID tag associated with a consumer item.
