RFID is a radio frequency identification. It could be used of rfinding something that is lost. If you losse something it would be easier to find it.In the future it may be used to track something especially to find something that is stolen. I would proably want my ipod to be tracked because i always loose it. No, i wouldnt want to be tracked because it feels like if you are always being watched, and if you cant do what you want.
