ABSTRACT:
A security seal for a freight car, freight container or other enclosure. The seal has an electronic timepiece which displays the time and date and is preset at an established reference time. A cut-resistant strap is secured at one end to the seal and has a latch at the other end. When the latch is passed through a lock and is engaged in a receiver in the seal, the strap is locked in place and the power to the timepiece is interrupted providing an indication of the time and date on which the lock was sealed. Other information may be applied to the seal at the time of sealing such as the identification of the individual responsible for the sealing.
