The project was abandoned after about ten years because the system proved unreliable after long-term use. The plates were read by a trackside scanner, located for instance, at the entrance to a classification yard, while the car was moving past. Two plates were used per car, one on each side, with the arrangement of the colored stripes encoding information such as ownership, type of equipment, and identification number. Developed by General Telephone and Electronics (GTE) and called KarTrak ACI (Automatic Car Identification), this scheme involved placing colored stripes in various combinations on steel plates which were affixed to the sides of railroad rolling stock. An early use of one type of barcode in an industrial context was sponsored by the Association of American Railroads in the late 1960s. UK magazine 'Modern Railways' December 1962 pages 387-389 record how British Railways had already perfected a barcode-reading system capable of correctly reading rolling stock travelling at 100mph with no mistakes but the system was abandoned when privatisation of the railways took place. However, it took over twenty years before this invention became commercially successful.

A mobile device with an inbuilt camera, such as smartphone, can function as the latter type of 2D barcode reader using specialized application software (The same sort of mobile device could also read 1D barcodes, depending on the application software). 2D barcodes can also be read by a digital camera connected to a microcomputer running software that takes a photographic image of the barcode and analyzes the image to deconstruct and decode the 2D barcode. 2D barcodes can be read using purpose-built 2D optical scanners, which exist in a few different forms. Later, two-dimensional (2D) variants were developed, using rectangles, dots, hexagons and other patterns, called matrix codes or 2D barcodes, although they do not use bars as such. These barcodes, now commonly referred to as linear or one-dimensional (1D), can be scanned by special optical scanners, called barcode readers, of which there are several types. Initially, barcodes represented data by varying the widths and spacings of parallel lines.
