Many of the bar code readers I've played with work like USB keyboards,
so just being able to accept numbers from a keyboard can be enough.

Another variant is to use a camera as a bar code reader.  I've seen it
demonstrated using HTML5/JavaScript as a front-end to a Warehouse
Management System written in Ada. ;-)
