Tesco lets shoppers self-checkout with their mobile phone at new Jack’s discount chain

Tesco spin-off Jack’s opens its doors with free mobile ‘Smart Shop’ app — Internet Retailing — “With the app, shoppers can scan the item’s barcode or shelf-front price code and then pay by simply tapping their phone on a self-service checkout terminal before leaving. The app also helps the shopper log what they have bought and how much they have paid.”
