Two-dimensional barcodes are used to systematically represent data by using symbols and shapes to encode data. The two-dimensional Quick Response Code, known as QR code, is used similarly to the linear 1D barcode but they present even more data per unit area allowing them to be used for plenty more. Businesses dictate what information will be defined and provided on their 2D labels. A business uses custom fields to create what data will be provided on each label.
QR codes are used to track, manage, market, and buy items. They are implemented in advertisements, magazines, and business cards. QR codes are commonly used in the retail space for POS transactions and in the entertainment space for advertising & marketing. 2D barcodes are flexible in their size and appearance. Unlike the vertical barcode, 2-dimensional barcodes can’t be read with a 1D laser scanner and pose a higher fault tolerance.
