SECURE DELIVERY SYSTEM

摘要

A delivery system comprises a docking station and an element for releasably connecting to the docking station. The element is preferably a chain or cable which serves to both hold closed a transportable container and plug into the docking station. A keypad or card reader is provided so that a recipient can remove the plug from the docking station and gain access to the delivered goods in the container. A deliverer uses either the keypad or a portable communicator to release plug so that containers can be returned to the supplier. The plugs may be individually coded so that the docking station can determine whether a plug is correctly inserted into a socket on the basis of information received from the deliverer's communicator.
