What are the different types of barcodes and what uses do they have?
Different Barcodes and their uses: Code 39 Code 39, also known as 3 of 9 Code and USD-3, is an alpha-numeric variable length symbology widely used- in non-retail environments. It is the standard bar code used by the United States Department of Defense and the Health Industry Bar Code Council (HIBCC). Code 39 may use a check digit, but may be used without a check digit. Code 39 is normally used to encode digits, upper case letters, and a few special characters. Representing lower case letters and most of the special characters is done using “full ASCII” mode. This requires twice as many bar code characters and consequently twice as much space on the paper.
