Biometric Business Security Goes Beyond Bond

From the article: "Before you couldn't count on the biometric solution - we saw a lot of what is known in the industry as false rejection rates," says Itay Langer from Israeli firm BioGuard.

And a seldom discussed problem exists along with false rejection: a false positive.

This is when an access control device allows entry to someone who is not enrolled. This is much worse than a false rejection. Before committing to a biometric access control system I would suggest investigating how often this nasty behaviour can be expected. If the saleman tells you 'Never', proceed with caution. It may be true, but it will might be a big problem if it is not true.
