VLC Electronic Label for Hypermarket

Abstract

This work developed a multi-function electronic label of product for hypermarket which mainly aims at improving the product information and safety for both consumers and hypermarket. This device applies the techniques of visible light communication (VLC) and adopts existing LED lights from hypermarket to manage uniformly all contents of product labels and provide emergency light. Master control system on hypermarket server can control LED lights to transmit signals to the electronic label. At the same time, when electronic label on product shelves from supermarket receives the signals, the label displays the product information such asprice, calories and so on. The emergency lights on the both sides of the label display board will illuminate during the blackout and lead consumers to escape from the hypermarket safely.
