Abstract: A computerized delivery-acceptance system has a delivery container (1) with a computer-control input door (4) and an outlet door (18). The input door has a lock (5) that can be unlocked by computer-controlled recognition of access authorization for placing delivery items (2) in the delivery container. After the delivery items are placed in the delivery container, the input door is closed and locks automatically. Then the outlet can be opened separately for receiving the delivery items. Computerized recognition (40, 13, 42, 43, 14, 44, 45, 11, 10), delivery-arrival indicia (16), memory backup (58), power backup (57), operational alarm (15), misuse alarm, compartmental containment, freezer containment (19), delivery records (16) and all-weather protection are provided as options.
