I have a question about the Dunkin Donuts app vs. the Starbucks one:
In DD->MyCards || Menu || Gifts
Form: Is that a scrollable UIViewController with 2 UIContainer viewcontrollers inside?
Function: buying a card is just a web server transaction but by the looks of it, it must use passbook because I don't see how it would present a purchased card? So it must mean the purchase sends you a passbook pass.
Oh well I just saw Starbucks and noticed that you can either use passbook or the app (by flipping over the card) to present the barcode in order to scan/update the app...
