摘要： A method and apparatus for encouraging return of shopping carts to the store including a detector and dispenser triggered by the return of a shopping cart belonging to the store, the device having a first photocell and light source detector which is sensitive to reflective indicia mounted on shopping carts belonging to the store. The first photocell is coupled to an ejector mechanism which ejects a reward medium, such as a game contest piece, to a pickup station. The piece at the pickup station interrupts the beam of light trained on a second photocell to thereby disable the dispenser until the piece is manually removed from the pickup station. The reflective indicia may be colored and a filter interposed before the second photocell.
