Uhhh...ok. Would he not give up his prints to cash a check?
I tried to cash a check at a bank once that needed a print. I walked out and cashed it elsewhere and never have gone back even though it is fairly close.
The government having prints, I don't like. The private sector, which can and do share information all the time, forget it.
What can you do with prints? Give me a sample of yours and I will show you. I can make a rubber stamp of one of your prints in about 30 minutes and apply it wherever I wish. Apply a little oil, gun oil should do it
and stamp your print on whatever. If someone wanted they could even remove thier own print, and using yours to make a mold actualy temporarily give thier fingers your fingerprints by making thier fingers heal with the mold. They would have your fingerprints for a short time until thier own grew back.
Try explaining to a jury how your fingerprints got somewhere you were not. Yeah right like they are going to believe that.
When you give people too much power, especialy unnecessary you are just putting yourself and your freedom at risk for no reason.
RFID is quickly being seen as having potential. Basicly a chip that when a radio frequency is applied responds with data. It is passive and essentialy allows you to be read like a bar code.
You could put RFID readers in doorways, and in passive checkpoints throughout a city. Make it illegal to not have one. Then use a computer program to watch where all the little dots (people) move throughout the day.
Much like London already tries to do with cameras and facial recognition software. Anyone passing through points without a reading would be breaking the law and could be detained. As long as you have nothing to hide...
This sounds far fetched, but the technology exists and is being implemented already for other purposes.
Check out this: they even install them in newborns.

Reading these passively is easy. People can scan others in public without them knowing.
Once someone is scanned a malicious individual can then make thier own device with the same signal and could pretend to be whoever they wanted.
They could cover thier own in lead or otherwise make it hard to read temporarily.
Too much information is too much information. Just because you cannot think of a way to use someone else's information maliciously does not mean others will not.
Even DNA can be replicated by someone with a sample if they have the resources. DNA is considered bona fide non disprovable evidence by many. It can actualy be replicated en masse and they sprayed or applied wherever.
You need a sample first though.
I don't yet know of a way to duplicate a retina for a retinal scan. However I imagine if one was to see the 2d image the computer creates, it could easily be used to make a fake "eye".
