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.

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.

An electronic key may include a partial capacitor comprising a capacitive metal plate in communication with a processor. The capacitive metal plate of the partial capacitor is configured to form a capacitor with a corresponding capacitive metal plate of a lock when brought into proximity with the metal plate of the lock. Data may be transferred from the key to the lock using a capacitor formed by combining the two metal plates, wherein a common ground is established between the metal plate of the key and the metal plate of the lock through a parasitic capacitance present between the key and lock circuitry.
