Rails - Sep 2012 - Biometrics fingerprint scanner in RoR? Is it possible? and how?

I''m a graduating student of IT right now and in a couple of months,
we''ll
be starting on a new project in the University. My group and I decided to 
create a voting system which requires Fingerprint scanner to identify the 
voters and make the voting process more secured. I still don''t know how
biometrics fingerprint scanner works exactly and I''ve just started to
do
some research.

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

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

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.

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.

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.
