Using microchips mounted to the LEDs, the ByteLight technology causes the LEDs to flicker too fast for the naked eye to see. In doing so it communicates information to a smartphone through its camera lens. The communication between light bulb and smartphone enables shoppers using a retailer’s mobile application to navigate through a store, receive special offers on the products in front of them, or be located by a sales representative. ByteLight says its margin of error is less than a meter. “The opportunity for indoor location is enormous. Several large retailers are testing ByteLight’s navigation technology as a tool for improving employee efficiency,” said ByteLight chief executive Dan Ryan.
