Abstract: A transport car with rollers, all of which are steerable, for which an activatable anti-theft protection is provided. With the anti-theft protection, two or more of the rollers may be fixed in a predetermined steering position whereby the angle which the rollers are fixed at relative to a longitudinal axis of the transport cart is different between the two or more rollers.

Abstract: A method and a system for detecting and rewarding the returning of shopping carts to the supermarket collection points is provided. During shopping, a first signal A is generated. When a shopping cart is returned, a signal B is generated. These two signals A and B are correlated either in the supermarket or in an information device that the customer carries with him or her, in order to deliver a reward for returning the shopping cart. When the first signal A is generated, the customer or an information device carried with the customer is identified. Alternatively, the signal is provided to the customer at the supermarket checkout so that the customer himself/herself can take steps for the correlation of the signal A with the signal B that is still to be obtained.

Abstract: A system and a method for detecting and rewarding the return of supermarket carts or luggage carts taken from a cart stand. Each cart is provided with a contactless, preferably optically identifiable, individual mark, by which the cart is identified when it is returned to a cart stand. In addition, the identifying mark on the cart changes when the cart is brought back to the cart stand, from an active state, in which the mark can be identified, to a passive state, in which the mark cannot be identified, or vice-versa. In addition to the presence of a returned cart, the invention enables the correct positioning of a cart in a row of nested carts to be identified in a contactless and automatic manner.

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.
