Hi and welcome to devnet,

That is too vague.
What device is that ?
How is it seen by your system ?
What OS are you running ?
What should your application do with the data from the scanner ?

You do not provide enough information.

As said before "fingerprint scanner" is way too vague. Again: what device is that ? How is it seen by your system ? Etc.

You realize that you are basically asking people to do your job ?

A 30 seconds search shows the fprint project which has a list of supported devices.

It is a very general question.
Some finger readers can store in them memory thousand of fingers.
When someone put the finger on it they send the code related to the finger.
Some others send the bmp image related to the finger. In this scenario you have to use a library that recognize the finger.
Depends about the device that you have shoosed.
