Barcodes

We recognize three basic categories of barcodes. The most well-known and oldest are linear barcodes, which are commonly referred to as 1D codes. Barcodes that are formed in a matrix by assembling individual dots, usually in square or rectangular shapes, are called two-dimensional codes and are abbreviated as 2D. The last category consists of three-dimensional barcodes, which are created by modifying 2D codes by adding color as a third element. The individual dots of these codes have different colors, thereby increasing their capacity.
