摘要

The identification of items uses a computer system to process product identification numbers during the transaction, comparing the product identification with a list of identifiers which are associated with a commercial advantage, such as a discount or reward. If an item, or group of items, on the list is detected the commercial advantage is immediately applied to the transaction.
