A network of cameras (14) is disposed throughout a store, such as a grocery store, for example. The cameras are positioned so as to monitor the products available in the store, as well as the entrances and exits to and from the store. Customers are identified (42) as they enter the store, and their movements throughout the store are tracked (44). The cameras capture images of the products selected by the customer and then send those images to a computer server (20). The server identifies (48) each product selected by the customer, maintains (54) a total price for all products selected by the customer, and automatically debits (60, 62) the customer's account for the total price upon detecting (56) the customer leaving the store. |
