Two-dimensional (2D) barcodes

Two-dimensional (2D) barcodes look like squares or rectangles that contain many small, individual dots.

A single 2D barcode can hold a significant amount of information and may remain legible even when printed at a small size or etched onto a product. 2D barcodes are used in a wide range of industries, from manufacturing and warehousing to logistics and healthcare.
