Emart is a populair supermarket in South Korea. But they have one problem, between 12 mid-day and 13pm there are practically no shoppers at all. That is why they created this special QR Code. Only between mid-day and 13pm the code could be tagged because it worked with the sun. People could then also order products which were delivered at home.
