Biometrics fingerprint scanner in RoR? Is it possible? and how?

Rails
1

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.

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.
