Abstract
A self service cart system is provided to speed throughput at a check out counter and thus reduce space devoted to check out counters. The cart comprises a bar code scanner for acquiring a price and a description of a product, a security scanner for converting a tag from an unsecured state to a secured state, a magnetic card reader for activating the cart and a controller. The controller stores the price and description of all products in a store and keeps a running total of the price of the products scanned and placed in the cart and coordinates the various activities of the various parts of the cart system. An inventory control computer is connected to the cart'"'"'s controller at the check out counter to down load the price and description of the products scanned. The products then pass through a security sensor which determines if the products are in the secured state and raises an alarm if the products are in the unsecured state.

-
a cart having wheels for mobility and an internal space for storing items; a plurality of products for sale having a bar code and a security strip attached to said product, such that the bar code and the security strip are adjacent or overlapping; a bar code scanner attached to said cart for optically reading said bar code on said item; a security scanner, attached to said cart being adjacent to said bar code scanner, for converting said security strip on said product from an unsecured state to a secured state; an electrically latchable door connected to said cart allowing access to said internal space of said cart when said product has been correctly scanned by said bar code scanner and said security scanner has converted said security strip from an unsecured state to a secured state; a communications port attached to said cart;
an inventory computer, separate from said cart, receiving and storing a quantity, a price and a description of the products scanned by said cart, through said communications port and down loading the current price of said products to the cart through said communications port;a controller attached to said cart in electrical communication with said bar code scanner, said security scanner and said latchable door, for
1) determining if the bar code scan was successful and the product is in the secured state, then releasing said electrically latchable door
2) determining which product was scanned, storing the quantity of the products scanned and the total price of all scanned products scanned and communicating this information, through said communications port and said communications cable, to said inventory computer;a magnetic card reader, a magnetic card and a password which activates the controller when the magnetic card is scanned and an appropriate password is entered; and security sensor remote from said cart and through which an products must pass, said sensor determining if said items are in the secured or unsecured state and raising an alarm if any of said items are in an unsecured state.
