Bar Code Programming

If you get a bar code scanner for PC, they just emit keystrokes as if you type the barcode number on the keyboard, which also makes it easy to support manual entry for barcodes that become unreadable.  You can get barcode fonts so that you can print your own, and you can put in anything you want.  Note there are several different bar code standards, so get a font you readers can read.  We use the wasp wand reader, which you can pick up at a lot of places, including CompUsa http://www.compusa.com/products/product_info.asp?product_code=50118263&pfp=BROWSE
