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

        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,

   [my english is bad... please sorry :-)]
