The best biometric support in Linux is provided by fprint:

There is some information on that site about supported devices -
mainly the built in fingerprint readers in laptops, but also some
external readers AFAIK. Most use is for authentication for PAM, for
login/sudo etc but I'm sure you can use it for other uses.

That said, for Time and Attendance usually a separate reader or
network of readers are used, which do all the biometric stuff in their
hardware/embedded system and the data can be downloaded over a serial
link into a PC and analysed there. This is probably much more costly
than a PC with a fingerprint reader because it is specialised, but the
plus side is that it is industrial quality.
