Fingerprint Reader in OpenERP7

Fingerprint Reader in OpenERP7

I have the need to integrate the fingerprint reader 'U.are.U 4500
Fingerprint Reader' to OpenERP 7. I have an idea of ​​how to
do it and I would like to share with you and get their feedback to
determine if it is a good way.
The first thing would be to develop in java (Reader API available) one
kind of 'http server' which answers requests for certain port and run the
capture, verification, validation of the trace requests and answer a code
status and other information such as the bytes of the fingerprint.
From OpenERP used that could consume web services that application done in
java and thus make communication with the fingerprint reader if need
applets and weird stuff.
You think of this way to communicate OpenERP with a fingerprint reader?
