Queue skipping

QThru is a mobile-enabled technology that allows shoppers to skip the checkout lanes by using their smartphones to shop, scan and pay. (Cheers Jamie)

Shoppers can view in-store specials, get product details such as nutritional information, view their personally-created shopping list and access a running total of their spending so far. To complete the checkout process, shoppers simply enter a passcode and scan a QR code at a checkout kiosk, which then generates a receipt that’s highlighted in a different colour for review by a store employee at the door. Simple. In theory, anyway!
