Is it possible to use fingerprint scanner for authenticating users on a
web application?

I have a web application created in asp.net which is being authenticated
using conventional username/password method. This application is just for
managing employees data and this authentication is fine, but a problem is
coming. currently all daily wage employees comes at the about same time
which makes a long queue before the receptionist and quarrel over their
time that they are standing here for last 5 or 10 minutes for getting
entry. Right now the BI is to collect a predefined amount from daily wage
workers before giving them entry, and if they are late then fine is also
added to this amount. This step of collection and verifying time take
at-least 1 minute - 3 minutes depending upon the quality of receptionist,
which make the exact time employee late. I had increased the late time in
backend but this was not practical as genuine late comers were also
granted entry without fine.
The only solution that comes to me is to getting some bioscanner installed
and linking them to the server. However I have never used a fingerprint
scanner before and just need to know it is fisible or not in web
environment.
It is a web application because their office are having 6 branches.
