Apple Previews Passbook App in iOS 6
Apple today announced key features of iOS 6, including an wallet-like app called "Passbook" that will be used to hold "boarding passes, movie tickets, retail coupons, loyalty cards, and more", all things that it refers to as "passes".
Quick summary of key features: The app uses 2D barcode technology to present passes to the merchant, merchants can update things like "available balance" and " current points" in the background, and geolocation technology is used for relevancy within the Passbook app.
Apple demonstrated how the available balanced on your Starbucks card would be updated automatically within Passbook upon completion of a purchase. In related news, Apple also announced they now have over 400 million cards on file in iTunes.
