Apple just announced that iOS 6 will have a feature called Passbook, which will integrate passes and tickets from all kinds of services: movie tickets, boarding passes, loyalty and gift cards, and more. It's all integrated into the lockscreen, and geolocation means the phone can pull up the appropriate pass when you get near the relevant store or location.

Apple demoed Passbook with apps from Fandango, Target, Starbucks, United Airlines, Amtrak, the W hotels, MLB.com, and — of course — the Apple store. The company says that it's easy for devs to use Passbook in other apps with templates, and the passes themselves update when things change — gate numbers on boarding passes and dollar amounts on gift cards update automatically, for instance.
