A newly published Apple patent application could lead to NFC (near-field communications) iOS devices but also possibly conflict with other device-to-device sharing plans. A "Device-to-device workflows" patent would set up a handshake between two devices that would exchange data in a multi-step script when the two get near. As an example, a primary device could request contact information, bring up the camera app to take a photo of the contact, and get a bookmark in the web browser to the new contact's website.
