To be clear, this patent is for the graphical user interface of a mobile payment app. This is not a patent for NFC technology, or mobile payments in general. It is simply a patent for the GUI of a potential app that one day may find its way onto the iPhone. No one is quite sure whether NFC will be found in the next iPhone, but Apple has been working on the app for 3 years now, apparently. According to the abstract, the app will have "credit cards... digitally represented within an electronic wallet or an online payment system. After movement of the graphical elements, the electronic device may transmit a confirmation message to initiate payment with the selected payment instrument."
The patent also shows a few different ways for the user to confirm a payment, including the ever-present swipe gesture, or other options like moving the device itself, or dragging an icon to a confirmation area.
