Abstract: The security system determines if the cargo area of a vehicle may have been opened in transit between a loading location and a destination location. The vehicle has an enclosed cargo area with a cargo door and lock. The system includes a digital counter which displays a number set thereon after the cargo area has been secured by locking the cargo door lock or by closing the cargo door.

The set number is forwarded to the destination location by entering it on the shipping documents or transmitting it electronically. At the destination location, it can be determined if the cargo area may have been accessed in transit by comparing the set number forwarded to the recipient by the shipper with the number displayed on the counter when the vehicle reaches the destination location.
