2D barcodes are used in manufacturing, warehousing, logistics, and healthcare, and they are popular because they are legible when printed in small sizes and when etched onto a product.ĢD barcodes include data matrix, QR code, and PDF417 codes. 2D barcodes hold a great deal of information and data because they store information horizontally and vertically in fact, 2D barcodes can store up to 7,089 characters, which is a much greater storage capacity than the 20-character capacity of standard barcodes. The first 2D barcode was developed by David Allais at Intermed Corporation in 1987. Two-dimensional (2D) barcodes incorporate rectangles, dots, hexagons, and other geometric patterns to form scannable squares and rectangles.
