Subway is one of the most popular fast food franchises in the world, and like all major chains, it has its very own loyalty system, the SUBCARD, for those who like an Italian BMT or a Meatball Marinara on a regular basis. Those more digitally aware will have long since ditched the plastic Subcard for the official app, which offers a QR code ready to scan at the tap of a home screen icon, and today, the UK version of the app on iOS has been updated to bring integration with Apple's fledgling Passbook app. More details and download link can be found right after the jump.
