Industrial 2 of 5 (Standard 2 of 5) Standard 2 of 5 is a low-density numeric symbology that has been with us since the 1960s. It has been used in the photofinishing and warehouse sorting industries, as well as sequentially numbering airline tickets. The symbology is called "2 of 5" due to the fact that digits are encoded with 5 bars, 2 of which are always wide (and the remaining three are narrow). Standard 2 of 5 is a very simple symbology in that all encoding information is encoded in the width of the bars. The spaces in the barcode exist only to separate the bars themselves. Additionally, a bar may either be wide or narrow, a wide bar generally being 3 times as wide as a narrow bar. The exact size of the spaces is not critical, but it's generally the same width as a narrow bar.

'Interleaved 2 of 5' Interleaved 2 of 5 is a higher-density version of 2 of 5. While it is reasonable to support Standard 2 of 5 for legacy systems, new projects should seriously consider using Interleaved 2 of 5 rather than Standard 2 of 5.

Characteristics of Code 2/5 Interleaved -Numerical Code - Self-checking - Continuous

Advantages - High-Density (Higher Information density) - Self checking

Disadvantages - Spaces are also used for Information - Low tolerance (low redundancy)
