Apple have just been granted a patent which could see future iPhones or even the iPhone 5 appear with NFC technology allowing users to check-in to airport terminals using just their smartphones.
The patent shows that Apple could well be looking to expand on its Passbook app, a new feature which was recently announced to be launching alongside iOS 6.
Passbook is at present more a hub containing travel information and visual ticket codes letting you gain access to train tickets, live entertainment events and also use store cards.
The acquisition of an NFC-related patent will naturally prompt suggestions that Apple could well be releasing the upcoming iPhone 5 with NFC or indeed be looking at placing the tech on their future devices.
