Kirk & Tony, We do lots of bar coding systems every year using wedge-readers (keyboard input), RS-232 wireless, and IP-based wireless. Going forward we are no longer doing RS-232 scanners as it is simply too much work for both us and our clients.
If a wedge-reader is the right tool, we use this first, otherwise all our projects are now IP-based scanners which are basically browsers. Our communication is via web services, which are very, very fast to develop and provide very fast network communication. The scanner displays on these units are small so generating HTML pages for this is really quite trivial. We have also done a number of IP-based tablets and all of what I said is also true here.

Tony, How are you handling programming the barcode reader to include information about what the barcode belongs to? Or are you using it as an extended keyboard input?
