Many older scanner don't support WEP as they don't have enough processing power. When they're just talking to an inventory system, it's not a big deal. Many businesses run that way. Do they care if you know that they have 59 cases of product #236977936 in stock?
The problem comes with tying in the cash registers, usually in an attempt to have real-time inventory tracking. Suddenly the registers are spewing out all sorts of stuff besides stock numbers. Swipe a credit card through and your name, account number, PIN, etc., goes right across the airwaves.
There seems to be an assumption the "no one will know about this..." That may have been true in with earlier systems, where there was a slim chance of people have the equipment to read the frequency and encoding. However, with everyone and his brother having 802.11 equipment nowadays, it is a completely wrong assumption.
