I've used one of these before. As the link points out:
"What exactly is a keyboard wedge? A keyboard wedge can be either hardware or
software. Let's look at the hardware type first. It's called a wedge because
it "wedges" in between the system keyboard and the computer console. The
wedge interface is built into the barcode scanner. Examples are our AS8113
and GT-7000 hand held scannes. Physically, the keyboard plugs into the
scanner and the scanner plugs into the computer console. When you type on the
keyboard, the characters are sent to the computer as usual. When you scan a
barcode, the barcoded characters are converted to keyboard "key codes", and
sent to the computer. So, the computer thinks that the data in the barcode
was typed on the keyboard."
Basically, it it pretends to be a keyboard. It plugs into the PS/2 port of
your computer, and your keyboard plugs in on top of it. When you scan a bar
code, it "types" out the code as if you had typed it in by hand. It will work
with any operating system that supports a PS/2 keyboard. No special driver
