9to5mac.com: “RFID reader built into the screen?Â We’re not quite sure why they’d need to do this (as opposed to putting the reader somewhere else in the device) but Apple has put a patent application on this.” – In addition, the US Patent and Trademark Office lists the following: “The efficient incorporation of RFID circuitry within touch sensor panel circuitry is disclosed. The RFID antenna can be placed in the touch sensor panel, such that the touch sensor panel can now additionally function as an RFID transponder. No separate space-consuming RFID antenna is necessary. Loops (single or multiple) forming the loop antenna of the RFID circuit (for either reader or tag applications) can be formed from metal on the same layer as metal traces formed in the borders of a substrate. Forming loops from metal on the same layer as the metal traces are advantageous in that the loops can be formed during the same processing step as the metal traces, without requiring a separate metal layer.” – I can think of several uses for an iPhone with a built in RFID Tag reader, it can already read barcodes. The iPhone just keeps getting cooler and cooler.
