What? Your papers ban be forged?
Then we all need to have an IFRD chip ( inserted into the brain ) to prove our 'identity'. One that explodes when it is removed.
There are things like fingerprints and retina scans and even the lines on your feet and palms that are unique identifiers. There's your DNA.
The RFID's main advantage is that you can be identified from a short distance away if there's a scanner in the area.
What's more useful to the police is your "smart" cell phone. It sends out a signal that goes for a half mile, and there are hundreds of reception towers in every major city. The phones can be reprogrammed to use the gps and wifi triangulation software, and then pinpoint your location down to several yards, and then send this location information to the police.
That information can also be linked back to your social network accounts, which are being data mined for information not only about your life, but your associates and friends lives too.
