Subway are not the first to start using barcodes on Smartphones instead of store card, Something very similar is also available in Starbucks only making use of a traditional 2D barcode instead. The data that needs to be presented for identifying a customer is small and so a 2D barcode is more than capable.
As well as replacing your card with a QR Codes, Subway also offer free games and treats through QR Codes scattered around their stores and special offers. Scanning the codes in store allows you to benefit from the offer.
