These labels use the classic black and white parallel lines and spacing to encode data. One-dimensional (1D) or linear barcodes are perhaps the most recognizable type of barcode. The spacing and pattern of the black and white lines might seem to be random, but they are not: they follow standardized code languages established by the International Organization for Standards (ISO).Ī barcode scanner will then read those images, detect the code, and then translate the information into a line of text that can be understood by a point of sale or inventory system.
