Bar-code Scanners for Linux?

peterjm asks: "Well, some one here at work has decided that the answer to all of our problems would be the acquisition of a bar-coder/scanner for labling and keeping track of all of our pc's in the office. A web hunt reveiled all sorts of the little suckers, but what I was wondering is, are there any bar-scanners that are designed (or have software designed) to run under Liunx?" Linux needs support for some of these if it wants to be considered as a possible tool in the retail market.
