Code 39 Barcode

Code39 is a symbology that is widely used in industrial bar code applications. It is discrete, self-checking, variable length symbology that can be printed readily by a variety of technologies. Every character has five bars and four spaces; three of the elements in any given character are wide, and six are narrow. Every symbol starts and ends with a unique start/stop character.
