Abstract
A system ensures payment for the purchase of merchandise carried through a checkout aisle on the lower tray of a shopping cart. For that purpose, the system includes a controller with an embedded program for identifying a virtual structure substantially equivalent to the physical structure of the tray. Further, the system includes a sensor that determines when a cart is positioned at the checkout aisle. The system also includes a camera for creating an image of the physical structure of the tray and transmitting the image to the controller. The controller includes a means for activating the embedded program to compare the image with the virtual structure. As a result of the comparison, the controller determines whether merchandise is on the physical structure of the tray. During the comparison, the controller removes the virtual structure from the image.
