There won't be room inside the slimmed down case of the iPhone 5 for the components necessary for NFC.
NFC would make payments possible using your iPhone. If you can already pay just by tapping your debit card at the checkout you'll be familiar with the technology.
It was thought that Apple would implement Near Field Communication (NFC) in the iPhone 5, however, a Cellphones report is claiming that when all the leaked iPhone 5 parts are assessed, there isn't room for the necessary components for NFC.
Instead new iPhone users will have to contend with Passbook, new in iOS 6. Passbook is a new app coming in iOS 6 that displays vouchers and receipts from companies that have designed apps to work with Passbook. A typically example is that you book a air ticket with a supporting company (say British Airways) and your ticket is sent directly to Passbook on your iPhone. Because it's location-aware it'll serve up tickets when you arrive at the airport, and the barcode displayed on the screen of the iPhone is your ticket to board the plane. NFC could be used in conjunction with Apple's new Passbook app, which will arrive with iOS 6 this autumn.
For many Passbook sounds like a poor cousin to the promise of NFC. Apple has, however, been granted a patent for an iWallet application that uses Near Field Communication (NFC) to allow iPhone owners to quickly find bargains, so while the technology may not be implemented fully in the new iPhone, Apple does appear to be utilizing some of its features. Apple's newly granted patent covers an application that will have a variety of features to help enhance shopping lists and speed up the overall shopping experience.
Another Apple patent also suggests that a NFC chip will be introduced in the iPhone 5, enabling users to quickly send iTunes gifts to one another.
Another patent indicates that Apple could use an NFC chip in future iPhones to control digital devices around the home, including other Apple products, games consoles, digital cameras, or even sprinkler systems and thermostats.
On 7 August, Apple was granted an NFC shopping list patent that could also be used in future iPhones.
