Starbucks Card Mobile App | Starbucks Coffee Company
Basally, this displays a barcode for the barrista to scan in that effectively gives you a free X, coupled with some backend code to authorize you to show that barcode at that time (via stored payment credentials such as a registered credit card) so the issue is, is the barcode the same all the time for the same drink, or is it dynamic? If it isn't dynamic, there will be a world of hurt...
