Abstract
An access control system prevents a mobile container from being compromised/opened during transit, through the use of a programmable electronic lock, which can be unlocked only by means of an enabled electronic key that has been programmed with geographical location data representative of the destination site of the container. When the mobile container arrives at its destination, the key is coupled with a comparator, which compares the geographic location information in the key with real time geographic location information from a geographic location detection unit associated with the mobile container. In response to a match, the comparator enables the key for a prescribed period of time. The key may then be inserted into the programmable electronic lock, which reads the key to determine whether it has been enabled. If the key is enabled, the lock can be unlocked, to provide access to the container.
