The question then is how good is the computer and how many hits do
they get on a partial set of prints?
If this does get melded with a number of other biometric parameters it
would be much more useful but fingerprints alone are usually only
valuable when you have the print and an otherwise implicated suspect.
The first step might be to get better samples of everyone's
fingerprints because those smudgy cards they have now are far from
perfect. That is from the fingerprint guy at my sheriffs office. He
said that when they actually submit these to the FBI for something,
about half of them are rejected.
The most recent ones I've had done were done digitally, not with ink.
Up here and until about a year or so ago, your digital fingerprint was
taken every time you purchased a gun from an FFL. It was transmitted
electronically at the gun shop while you waited and the approval of the
sale was almost immediate. The purpose was to ensure it was really
*you* and that you had an active and current gun permit ... which also
means you had had a background check. The state replaced this system
with a "pin" number assigned to you. You have to provide it as well as
present your gun permit in order to purchase a firearm.
Sorry, I guess I am old ;-)
The only tome I have had a digital fingerprint was at Busch Gardens
and they had problems with it. I kept being rejected.
Maybe my fingers are a little different than the general public.
