Interleaved 2 of 5 (ITF) is a continuous two-width barcode symbology encoding digits. It is used commercially on 135 film, for ITF-14 barcodes, and on cartons of some products, while the products inside are labeled with UPC or EAN. ITF was created by David Allais, who also invented barcodes Code 39, Code 11, Code 93, and Code 49.
A barcode or bar code is a method of representing data in a visual, machine-readable form. Initially, barcodes represented data by varying the widths, spacings and sizes of parallel lines. These barcodes, now commonly referred to as linear or one-dimensional (1D), can be scanned by special optical scanners, called barcode readers, of which ...

Industrial 2 of 5. [1] (also known as Standard 2 of 5 [2][3][4]) is a variable length, discrete, two width symbology. Industrial 2 of 5 is a subset of two-out-of-five codes. [5] Industrial 2 of 5 is one of the first 1D and oldest barcodes and can encode only digits (0-9). It was invented in 1971 [6] by Identicon Corp. and Computer Identics Corp.
