Abstract
A cart management apparatus and method for retaining and vending carts such as luggage carts, shopping carts, and strollers, includes a retaining device for selective retaining at least one of the carts; a cart identification sensor for uniquely identifying carts retained by the retaining device; a control device for controlling the vending and returning of carts, wherein the control device maintains a queue of carts identified by a cart identification sensor and retained by the retaining device; a reward device for dispensing a reward when a cart is returned to the retaining device; and a counter for counting a number of times that an identification of the cart is missed from the queue of carts so as to prevent the reward device from dispensing a reward when the number of times exceeds a predetermined value of the counter.
