Bar Code 39
CODE 39 is an alphanumeric symbology with some ASCII characters available. Although it is a self checking symbology, check characters may be used when number integrity has a high priority. State-of-the-art handheld scanners; however, make the use of this check character redundant. According to ANSI Standards, Code 39 has a standard density of 9.4 cpi (characters per inch) but greater cpi is possible. It is important to remember that the narrow element in a high-density code can be a problem to some scanners, which makes it imperative that all the equipment used to read these ultra high-density codes be checked for compatibility before any ultra high-density labels are specified. Because of its alphanumeric capability, it is possible to produce more than 102 million unique labels with only 5 characters.
Code 39 is accepted by AIM, NEMA, DOD, NASA, and most FORTUNE 500 companies.
