RE: Tracking Arrow of the future
I could see how RFID technology could work with this, but real-time GPS tracking technology for the public would most likely never happen. The public has the wrong perception about GPS. It you have the GPS if will track you and show you where you are at, but for someone else to know where you are at, just by using the GPS, is very restricted. The goverment owns the sattelites and they can see who is using them and where they are, but that's about it.
Now the RFID technology is something else. They are as small as a flea and are being used everywhere nowdays.
