Apple patent hints at implementation of NFC in iOS20
In addition to explaining how the rules work, the filing goes into iTunes interaction with the feature. The desktop store could allow users to view statements and to be alerted when they are about to spend more than a pre-determined limit. Apple has been considering multiple patents on the NFC technology and Mastercard has recently stated that it wants to have every platform support NFC mobile payments which would imply that it has been talking to Cupertino.
Right now in the States, mobile payments are limited to the availability of NFC on just two Nexus smartphones, the Sprint Nexus S 4G and the Samsung GALAXY Nexus, and Mastercard's system. This leaves Google waiting for Isis mobile wallet to launch in the middle of the year or for Google Wallet to be available on more handsets. Once either occurs, NFC will get broader distribution. Apple will probably need to throw its support behind one or both of the mobile wallets although with its patent, iTunes could be used as a mobile wallet which would allow iOS users to have a complete NFC mobile payment option.
