I've mentioned before that I think Apple could add another unique feature to the iPhone 5 and that it might be NFC. My reasons for thinking this were that Apple gave the 4S Siri last year to make it a little more unique. When Apple [AAPL] announced iOS 6 they also announced Passbook which essentially uses the GPS/WiFi to track where you are and when at specific locations it loads up voucher codes, boarding passes and other items for you to have scanned in by a scanner. By adding NFC on the new iPhone, it opens up the possibilities of simply tapping your phone on a sensor (or hovering over it) to make payment or use a pass.
So, what appears next is a new part leak that appears to have some sort of NFC functionality embedded.
