So my question is, is it even possible that RoR can use a biometrics fingerprint scanner? 

I'm pretty sure that the biometrics fingerprint scanner should be able to output something if a user is a registered voter or not.  You just have

to hook this something into the database to check who the current voter is.  So overall, the question is not really if you can do this with rails, it's if the fingerprint scanner gives you flexibility to do this.

I've been searching the net (until now) if there are some tutorials or tips that could help me do this project using RoR..

Firstly, it doesn't seem right to make a decision while you are still unsure if that is doable by the deadline. In theory I don't see why it couldn't be possible, just it could require a lot of work. But isn't it the point for your group of educated people to come up with something in such a project thus enriching the knowledge available for RoR community?

P.S. I gather from your post that this is a non-commercial project designed to prove your expertise in the field.

This is not a rails question at all. It's a web browser & fingerprint scanner question.

Is there any way to access fingerprint scanner results from a web browser? If so, using RoR to handle the backend of the web application is no different than any other web app. If not, rails certainly can't help you around that roadblock.

A lot of these external hardware devices talk to the host computer over USB, and some I have used (barcode scanners) basically pretend to be a keyboard typing really fast. I have no idea how your fingerprint reader is meant to interact with the host computer, but I would start by reading its manual and figuring out how it was meant to connect to a stand-alone PC. Then see how you can go from there. You could have a button to "start" the scanner, which would use JavaScript to shift focus to a hidden text field and wait for the scanner to "type" the results into that field. Poll the field for changes, and after a change and a pause (to avoid catching it half-way through a change) send the form to your Rails server. The rest, as others have said here, is as easy as Rails.

Not technically a web browser question, as you could use a native app to handle the interface with the user, the fingerprint scanner, and the backend.  However, as Rails is only the backend, there is still no way this can be construed to be a Rails question.
