Johann,
You could either use a web app or a Java Client here. Many input
devices simply emulate the keyboard and so can enter their scanned
data directly into a regular INPUT element on a web page. Some
Javascript here could automatically submit the form to your WOApp or
do some Ajaxy stuff.
However, I implemented a GUI JavaClient App when I needed to use a
handheld barcode scanner. It's remarkably simple to hook up your
JavaClient EOs to the WOApp on the server in order to send your input
data to it.

Florijan's page is all you need, but if you want I could probably
resurrect what I did to get you started.

Hi list,
I am just thinking about what possibilities exist to get input data
from a device that is connected locally to the client (e.g. a
security card reader or a barcode scanner) into WO. An app deployed
as Java Client could easily interact with local devices but what if
a have a "normal" WO app? AFAIK JavaScript cannot access resources
other than the webbrowser itself and I didn't find any helpful
information on that matter.
Did anyone solve that problem or has any insight on how it could be
done? I can't imagine that this is a totally uncommon situation.
