Abstract
Systems and methods for a tamper-evident cargo container seal bolt lock are disclosed herein. The device can include a bolt member having a conductive medium running the axial length of the bolt, and a receiving member for locking the bolt into place. A battery-driven sensory circuit including a memory means, a processor, and a timing circuit can be disposed within the receiving member such that a continuous circuit is formed from one circuit pin over the conductive medium through the length of the bolt and back to a second pin. The sensory circuit is 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 time and/or date in memory. This information can then be transmitted to an RFID reader/interrogator if a dispute arises as to when the lock had been broken.
