Abstract

An electronic menu display system for use in a restaurant, including a plurality of portable menus. Each portable menu includes an electronic-ink display label for displaying graphical indicia on the electronic-ink display label. One or more activation modules are located within the restaurant, for providing instructions employed in the determination of graphic indicia to be displayed on the electronic-ink display labels of said portable menus. The electronic-ink display label employs an addressable display assembly including a layer of electronic ink including a bi-stable non-volatile imaging material. The electronic-ink display label includes an integrated circuit structure having a storage element for storing instructions, programs and data, and a programmed processor in communication with storage element. A signal receiving structure receives electromagnetic signals from the activation module, using the antenna structure. The electronic-ink display label displays graphical indicia representing information relating to the restaurant and/or food and/or beverages being served therein.
