An automated retail checkout system includes scanning terminals operable by either customers or store personnel, and payment terminals which service a number of scanning terminals. The scanning terminal communicates with a central processor for determining prices from the coded identities of products. Electronic payment can be optionally accepted at the scanning terminal, or a transaction is opened there and closed when payment is accepted at a payment terminal, also coupled to the central processor. Video monitoring allows the image of the products being scanned to be compared with the image expected from their scanned code, for identifying any discrepancy. |
