I have no idea what the heck RFID is and why we need it in an iPhone. Can anyone give an example of how this technology can be used in the iPhone?
There are two possibilities, an RFID tag and an RFID reader/writer.
A tag would be used to identify your iPhone with services where a plastic card or tag is used, usually for payments, door access, hotels, check-in systems, device tracking, inventory management.
A tag inside the iPhone could be of the "active" type (powered) for range and functionality. Encryption is included in most RFID tags nowadays.
An RFID reader is also an interesting proposition. It could be used to identify objects, identify users, recognize accessories, mark all of those as "visited".
Applications are, as always, limited by your imagination:
-Holster detection
-Auto settings per user, per location, per accessory
-iPhone and accessory security
-Exhibit interaction
-Product id, inventory, tracking
-Games, where you identify tokens/cards/board spots, or simply pass the iPhone around.
-iPhone service and manufacturing (Apple internal)
-Capture iTunes gift cards instantly (+short PIN
🙄 )
-Capture contact info from driver's license, etc.
-Sell songs/movies/apps in stores using special gift cards
-Electronic post cards
-etc etc etc
