Abstract: The display rack comprises a screen, connected to a control circuit, supports for products, furnished with RFID tags, and at least one radiofrequency antenna connected to the control circuit. When a product is removed from the display rack, a multimedia message corresponding to this product is broadcast. When a manager introduces an administration tag, of RFID type, into a zone covered by the antenna, its presence is detected and an administration interface displayed. This interface indicates a type of new product to be placed on the display rack. The identification code of the tag of a new product introduced onto the display rack is automatically detected and associated with the type of product considered. The control circuit can, moreover, cause the broadcasting of a comparative between two products when the latter are removed from the display rack in less than 20 s. A presence detector can allow the broadcasting of appropriate messages upon the approach of a customer.
