License Plate bar codes, what does that mean?
No, that’s not bar coding for the Motor Vehicle Office. Bar codes are often used to tell a computer to look up more information. Your bar coded part number “74701” may be a black stapler. You know that it’s the manual desk model. The computer at the store knows a “74701” costs $12.95 in their price lookup file. The term comes from the concept of a car’s license plate. When a trooper pulls you over and runs your plate number, the license plate keys a database of all kinds of information, “So you have seven outstanding warrants eh?” Most bar codes are used this way.
