A 2D barcode, also known as a two-dimensional barcode, is a type of barcode that can store more information compared to traditional 1D barcodes. Unlike 1D barcodes that consist of a series of parallel lines, 2D barcodes use patterns of squares, dots, or other geometric shapes to encode data. They can store various types of information including text, numbers, URLs, and even images. Examples of 2D barcode formats include QR codes, Data Matrix codes, and PDF417 codes. 2D barcodes are commonly used in applications such as product tracking, mobile payments, ticketing, and inventory management.
