A system prevents non-payment for goods carried through a checkout aisle in a shopping cart. In the system, a scale determines the end-weight of the cart after all goods are presumably removed. Further, a controller compares the end-weight and the tare weight of the cart. When theft is suspected, a camera captures an image of the cart while an indicator at the checkout location alerts the cashier to inspect the cart for unremoved goods. Specifically, the controller creates a signal when the end-weight exceeds the tare weight to instruct the camera to capture the image and to activate the indicator to alert the cashier. The controller may include or be integrated into a network accessible by store management or outside security advisors to examine the performance of cashiers and to determine possible patterns or profiles for theft.
