The next-generation iPhone 5 leaks continue, this time seemingly revealing a built-in NFC module. NFC code has been found in iPhone prototypes, and Apple has even patented its method for including NFC into a future iPhone--and it just so happens that the patents and the location of this new chip match up perfectly (the top-left corner of the front of the device.) At the iOS 6 reveal, Apple showed off its Passbook digital wallet app. Since then, many have commented that NFC might be the perfect companion to Passbook. We'll find out on September 12.
