A receptacle for supporting a transponder on a support structure includes a housing having a first housing portion securable to the transponder and a second housing portion securable to the support structure. The first housing portion is pivotally secured to the second housing portion. The first housing portion and second housing portion include a shield for attenuating the transmission of electromagnetic signals. The first housing portion has a first position wherein the first housing portion and second housing portion form a chamber for enclosing the transponder and restricting the transmission of electromagnetic signals from the chamber. The first housing portion has a second position wherein the first housing portion and the transponder are displaced from the second housing portion thereby opening the chamber and exposing the transponder to permit the transmission of electromagnetic signals to and from the transponder.
