ABSTRACT:
A shelf tag comprising a liquid crystal display having optical states which are stable without power and an interface that allows for each character element to be programmed easily by sweeping a programming device across the character element contacts with all power and signal requirements being supplied to the shelf tag by the programming device. The programming device can be integrated with a portable transaction computer equipped with a bar code reader or can be embodied in a stand-alone apparatus capable of receiving user input, displaying information and interfacing to the shelf tags. A method of using the shelf tags, the programming device and a radio frequency computer local area network are presented which automates many typical business applications such as inventory updating and simultaneously changing prices advertised on the shelf tags.
