Apple has filed for two new, potentially significant patents. One of these covers an "integrated coupon storage, discovery, and redemption system" similar to Passbook, an app built into the iPhone version of iOS 6. The filing
describes a "coupon wallet" which can accept input from several sources, such as scanning, email, touchscreen entry, or delivery via server. Coupons can be stored on-device or on a server, and the proposed app could also notify people about expiration dates, or when a person is in proximity to a place where a coupon can be used. Geofencing is already a feature of Passbook, and content is synced across devices via iCloud.
