Abstract : This patent application discloses a locking device for a transportable container. The locking device can only be opened when the container has arrived at its destination. The locking device includes a lock having a movable bolt, a motor for moving the bolt and inputs for connecting a power source to the motor. The locking device also includes a relay having isolated input and output circuits. The output circuit contains the motor and the power source inputs. The input circuit contains a Global positioning System receiver. The Global positioning System receiver determines the coordinates of the lock, compares them to those of the preset destination, and outputs a signal to the relay to supply power to the motor only when there is a match.
