Abstract
The invention is a bolt-type seal lock for use with shipping containers or similar kinds of applications where seal locks are needed. The seal includes a bolt and a separate locking body. The locking body holds a locking mechanism that engages with an end of the bolt when it is inserted into the locking body. The locking body houses a flash memory or equivalent electronic storage device that stores shipping or transportation data relating to the contents of the shipping container. The seal also has a locking mechanism that can be released by a special tool through a lateral access opening. The lateral opening is covered by an identification tab that serves as an identification mechanism for indicating seal tampering and as a barrier to access to the locking mechanism. The identification tab is replaceable which makes the seal recyclable and reusable by shipping companies having a need for large numbers of bolt-type seal locks.
