2D Barcode
What is a 2D Barcode?
A matrix code, also termed a 2D barcode or simply a 2D code, is a two-dimensional way to represent information. Unlike 1D barcodes, 2D barcodes use horizontal lines, shapes, or even images. In order to ensure high readability, 2D barcodes have features including error correction mechanisms and symbol contrast.
