I have worked for 7 years at a company that makes access control
solutions (with badges or tags).
Sometimes customers asked for fingerprint readers, and the company has
them in the product catalogue, but only because of customer demand - not
because it is a reliable solution. You can only use them in office
environments, not in production environments. Even in relatively clean
environments, the reliability is somewhere between 95-99%. What does
that mean? In a large company of 1000 people, you'll have to fire 10 to
50 people because their fingerprints "don't work". What if one of them
happens to be someone of upper management...

Imho fingerprint authentication is only useful as a secondary
verification, in combination with something else like a pin code. And
read this month's C't to know how you can fool fingerprint scanners.

To conclude: fingerprint identification does _not_ work as in CSI.
Forget it, that is just television. In Real Life it is much harder.
