Code39 class

The Code39 is a discrete, variable-length symbology that encodes alphanumeric characters into a series of bars. A special start / stop character is placed at the beginning and ending of each barcode.

Code 39 is self-checking, a check digit is not usually required for common use. For certain cases, applications requiring an extremely high level of accuracy of the checksum digit can be added.

Allows character set of digits (0-9), upper case alphabets (A-Z), and symbols like space, minus (-), plus (+), period (.), dollar sign ($), slash (/), and percent (%).
