 CODE
39 — Code 39 is probably the most widely used symbology after
the U.P. C . / E A N code. It meets the needs for many applications in a large
variety of indus-tries, including the Department of Defense (DoD), General Services
Admin-istration (GSA), the Automotive Industry Action Group (AIAG), and the Health
Industry Business Communication Council (HIBC). Code 39 encodes alphanumeric data
in any length, including the full ASCII charac-ters. It will also encode decimal
numbers, the upper-case alphabet, and some special symbols. It works with the
greatest selec-tion of printers and scanners. This symbol, created by Intermec
Technologies in 1975, uses nine ele-ments: five bars and four spaces. Of these
nine elements, two of the bars and one of the spaces are wider than the rest.
Wide elements represent binary ones (1), and narrow elements represent binary
zeros (0). |
