A couple of years back someone used my credit card number for about $500 in purchases. The credit card company very easily wiped it from my records. I signed the statement and the charges went away. But nobody pursued the criminal. Nobody even cared. It's only $500 bucks. Until law enforcement takes a real interest in catching people committing these crimes, fingerprinting the populace is a lousy idea.
So, your concern is that somebody is going to hack into the DPS, steal your identity, and modify your fingerprint? Sanity check me, but isn't looking at a phone book, and getting your address a little bit easier than going through that mess. I had my identity stolen too, and the %$& fools at American Express sent the thief my AmEx card to a hotel, about 5 miles from my house (instead of mailing it to me); and to add even more stupidity to their monunment of ignorance, they always type your SSAN on the placard that holds the AmEx card. So, instead of simply giving an identity thief an AmEx card, they gave him my SSAN as well.
Thieves will take the easiest way to acquire information they can. AmEx goes out of their way to make it easy for them to do so. The idiots STILL do not have a security question (mother's maiden name, ect). I think anything that makes a legal form of ID harder to forge, and more accurate; is a great idea.
