And it is generally lesser than 1D a single. More intricate scanner is necessary to study this sort of barcodes. What is a theory of barcode do the job? It's a mix of distinction marks that scanner can examine and decode. For 1D barcode it can be black and white vertical traces of different thickness. For second it is often a pattern of square dots.
