The video above shows a typical customer experience. Using the app a customer scans and bags items as they shop, keeping track of their total and being notified of any relevant specials. At the end of the shopping trip an instruction routes the shopper to a special checkout area, where she checks herself out by scanning a QR code. If there are any special flags on her purchase, such as an age restricted item or a need for a bag check then a light calls a staff member to assist.
