Abstract

A product information display system has electronic display tags (20) for displaying pricing and product information for products in stores or warehouses. The electronic display tags (20) are electromagnetically coupled to a conductor (423). A control circuit is used to generate an information signal which contains a tag address and related data.
A modulator circuit modulates an ac power signal with the information signal and applies it to the conductor for transmission to the display tags (20). Each of the display tags (20) is equipped with a coil that is electromagnetically coupled to the conductor for picking up the signals carried by the conductor.
