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

I used to work for a company that deployed a palm scanner for a time clock,
the palm scanner had little pegs that fit between your fingers to make sure
you had you hand in the same place all the time, you still got denied once
in a while, but it was much less.  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.

Biometrics are tricky. 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.

Hello list!

   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? (voice,
   eye, ??? what else).

   I'm not a security expert :-)

   Thanks a lot,

   Felix
