2D Codes Step By Step - Barcode Test

Let’s be clear about nomenclature. A 1D or linear barcode is a series of parallel lines and spaces of various widths. A 2D symbol is not technically a “barcode” since it is not consistent with the 1D barcode description; it is therefore more accurately called a “symbol” or a “matrix symbol” rather than a “barcode”.
