Abstract
Systems and methods for a tamper-evident cargo container seal bolt lock are disclosed herein. The device can include a receiving member, a conductive bolt member adapted to be snap-locked into the receiving member, and a plastic encapsulant which tethers the bolt member to the receiving member. The encapsulant can contain an electrically conductive medium, such as a wire, which runs from the receiving member to the second end of the bolt. A sensory circuit disposed within the receiving member can be configured to sense whether the circuit has been interrupted (e.g., if the bolt has been cut). In the event of an interruption, the circuit can record the present time and/or date in memory. An RFID transponder disposed within the encapsulant or the receiving member can then transmit the recorded date/time to an RFID interrogator if a dispute subsequently arises as to when the lock had been broken.
