Wall Street Journal Says Apple Is "Going Slow" On Mobile Payments
On the basis of this article, I reckon that the next iPhone will have NFC but it won’t have support for mobile payments. It’ll be used for a more elegant execution of Passbook, for instance, but the iPhone 5 won’t become your wallet.
Next year, or whenever, Apple decides to enter the mobile payment market properly, Apple can then push a software update containing the functionality, which the iPhone 5 will be in a perfect position to use, as it already has the NFC chip inside. This means that when Apple enters the merchant space, they will already have a large base of customers who can exploit their take on the “mobile wallet”.
