Starbucks' mobile payment app works on QR code technology as well, but uses it backwards. The app generates a QR code that contains the user's payment details. When the user's phone is scanned by the existing POS system at a Starbucks outlet, the amount due is debited automatically from their account. The genius in this system is that instead of printing a QR code in the receipt and letting the user scan it to make payments, Starbucks instead modified its existing infrastructure to accept payments.
