Barcode scanner interface for JSF app, Applet or JWS?

i wanna ask you about your opinion: I work as independent software developer, and i have a project (i haven't started yet) about develop a web software that can use barcode scanners to read information of products to use in a POS. I usually work with Seam 2 Framework (Richfaces & Primefaces) and i wanna use this framework for this app, but sincerely in my life as java developer, i never developed an applet nor JWS application, so i wanna ask you:

Do you think that is possible to develop an web application JSF Seam 2 that uses barcode scanners using applets, JWS or another technology?
If that's possible, which is better for that situation, according to technical aspects like interaction with JSF or with JAVA model components of my application, is more recommended to use Applets or JWS for barcode scanner interaction?

Regards.

Solution

Most barcode scanner simply act as a kind of keyboard - when a barcode is scanned the OS driver simulates keypresses corresponding to the digits of the barcode. So any non-daft application can "work" with those scanner on a very fundamental level.

If your app can get away with barcode-data in every input-field you could still use JSF.
