  • Publication number: 20090050441
    Abstract: The invention relates to a method of securing shopping trolleys (10), for which a defined parking area (9) is provided, by a deposit and to a deposit system for such trolleys. The deposit (7) is introduced into a deposit device (30) which is arranged in the parking area (9) separately from the shopping trolleys (10), the deposit device (30) freeing a shopping trolley (10) for removal from the parking area (9) by means of a signalling arrangement (18). The signalling arrangement (18) here interacts with an inhibiting device (26) on the shopping trolley (10) for inhibiting the movement of the trolley by remote control, the signalling arrangement (18) communicating in a wireless and trolley-specific manner with signalling devices (22) on the shopping trolley (10) and the signalling arrangement (18) registering the return of a shopping trolley (10) in order for the deposit to be refunded.
