Philips is testing a new lighting system in a handful of grocery stores that uses “smart” overhead lights to tell your smartphone the easiest route to items on your shopping list or ingredients in your favorite recipe. The technology is called “Lifi” similar to “Wifi” but using flickering LED lights to transmit data at a rate not visible to the human eye.
If installed in a grocery store a “road map” of your recipe can be sent to your phone and will guide you efficiently to each ingredient. No more wandering up and down the aisles.
