An interesting scoop from Cult of Mac:
If the iPhone 5 does have NFC, applications like an eWallet are a no-brainer. But we’ve been told that Apple is also researching NFC for remote computing.
For example, a NFC iPhone will allow users to carry a lot of their desktop data and settings with them — and load that data onto a compatible Mac.
If users wave a NFC-equipped iPhone at a NFC Mac (they need to be in close proximity to interact), the Mac will load all their applications, settings and data. It will be as though they are sitting at their own machine at home or work. When the user leaves, and the NFC-equipped iPhone is out of range, the host machine returns to its previous state.
“The Mac authenticates with the iPhone, which contains a lot of the information the computer needs, such as bookmarks, passwords and other data,” said our source, who asked to remain anonymous. “The system would essentially turn any Apple computer into your own — like you’re actually working on your own computer. Same settings, look, bookmarks, preferences. It would all be invisible. Your iPhone would be all you needed to unlock your Mac.”
