A portable electronic device. Tamper-resistant circuitry for inclusion in an electronic device. The tamper-resistant circuitry comprises wireless receiving circuitry operable to receive an incoming communication. The tamper-resistant circuitry also comprises a first circuit operable to change a signal state in response to the incoming communication. The tamper-resistant circuitry also comprises a verification sensor circuit coupled to the first circuit. The sensor is operable to detect a circuit condition indicative of unauthorized use and upon detection of the circuit condition to prevent the change of the signal state.
