U are talking about hand geometry. they do not actually scan the palm, but measure the had with those pegs as reference points rgds -Naveed

It was a big PITA when you got denied 3 times, you had to goto management, get them to come to the scanner, enter their codes, then try again. Perhaps thumb scanners could implement the same sort of thing, but instead of pegs, use a little gadget that holds the rest of your hand in place, to decrease the chances of denied logins. - - -----Original Message----- From: Bryan E.

One thing to think about it how to revoke users. There are a lot of great companies that make the fingerprinting stuff including ethentica and a lot of others. Try to pay close attention during your installation to the user management. AS to your question on how secure: the answer is the more secure it is the bigger pain it is for your users. If you make it so that the tolerance is not very high (your finger must be placed on the sensor exactly the same way every time) it's pretty good - but then your users may get frustrated with false refused log ins. If you set the system to more tolerant modes (you can put your finger on 'close' to the same way every time) there will be more false accepts but less log in refusals.. It's all a trade off.

I will work in a project where phisical security will be based on biometrics, in fact only will be based on fingerprints biometric. How secure are fingerprints?, what biometric are more secure?
