ABSTRACT:
A system for detecting and rewarding the return of shopping carts to collection points is provided. A signal corresponding to a dividend is generated as soon as a shopping cart is returned to a collection point. The signal is only generated when the shopping cart is returned correctly to a row of shopping carts. The correct return of the shopping carts is monitored by a digital image processing camera or with an optical signal transmitter which cooperates with evaluation units disposed on the shopping cart.
