Abstract

A band, label or tagging device for carrying identifying information about a person or object. The device includes a circuit host and antenna disposed on different substrates such that the substrates must be bonded together during the manufacturing stage in order to form a workable identification circuit. The bonding medium between the first and second substrates is such that upon an attempt to tamper with or remove the device, the first and second substrates will separate thus separating the circuit host from the antenna and disabling the communication circuit. The communication circuit may also comprise a circuit host with transponder and an antenna placed within the communication range of the transponder. Alternatively, the circuit may comprise two circuit hosts and two transponders placed within communication range of each other thus forming an enhanced ranged communication circuit.
