A delivery system

摘要

A delivery system for goods in which, based on a goods delivery request from a seller (seller's processing unit 2), a deliverer's processing unit 6' stores goods delivery information. When goods are delivered to a receiver, the deliverer's processing unit 6' generates the third-party delivery certification information containing the receipt signature of a receiver or the substitute signature and a payment ID related to the goods purchase. Based on the receiver's returned goods delivery request, the returned goods delivery information is stored and the first third-party return-of-goods certification information containing the receipt signature of the receiver who requests the return of goods or the signature of a substitute and a payment ID related to the goods purchase is generated. <IMAGE>
