| 1. An identifier for attachment to an object, comprising:
a substrate having an electrically conductive coil which forms an antenna of an RFID transponder adhered thereto by a first
strength of adhesion;
an electrically conductive path disposed in proximity to and in reactive electrical communication with the electrically conductive
coil; and
an adhesive layer for adhering the conductive path to an object such that when the identifier is removed from the object the
electrically conductive coil remains adhered to the substrate and a portion of the conductive path remains adhered to the
object to interrupt the reactive electrical communication between the electrically conductive coil and the conductive path,
the identifier exhibiting a first response to radio frequency signals when the conductive coil is in reactive electrical communication
with the conductive path and exhibiting a second response, different from the first response when the reactive electrical
communication is interrupted.
