Method and system from detecting and rewarding for the use of a shopping cart in a hypermarket

摘要

A system for detecting and rewarding the use of a shopping cart in a supermarket. All shopping carts are provided with an optically identifiable individual identification and, at the same time in the supermarket, detection means are available for automatically and optically detecting this identification and thus for automatically and contactlessly detecting the presence of the shopping cart in the supermarket. The individual identifier of the shopping carts preferably is a bar code or a series of numbers and/or letters, and the detection device includes a digital image processing camera or a scanner. The reward for using a shopping cart can be issued in the form of an entry in a lottery and/or can be made dependent on the proper return of the shopping cart to a collection point.
