  • Patent number: 8145531
    Abstract: In one implementation, products in a shopping cart are provided to a point of sale system. The products are removed from the shopping cart and scanned with a transducer system. A database association system queries a database and determines the likelihood that the scanned products are indicative of products located in a lower support unit of the shopping cart. A notification is displayed on a user interface indicating the possibility of products located in the lower support unit of the shopping cart. A user is then queried as to whether a product was located in the lower support unit and the association system is updated to reflect a revised probability that the scanned products are indicative of products located in a lower support unit of the shopping cart.
