4th gen iPhone could get RFID reader

Word on the street has it that the rumored fourth generation iPhone from Apple will come with an RFID reader. This could very well be true since Apple has already submitted several patents involving iPhone RFID. The patents also describe technology which sees an RFID reader embedded within a device’s touchscreen. Apart from that, the patent claims will encompass methods that enable the iPhone or iPod to work as a tag, making way for authentication with other devices.
