Detailed explanation-1: -A QR code (an initialism for quick response code) is a type of matrix barcode (or two-dimensional barcode) invented in 1994 by Japanese company Denso Wave. A barcode is a machine-readable optical label that can contain information about the item to which it is attached.
Detailed explanation-2: -Many people think QR Codes and DataMatrix Codes are 3D when they are not. Neither are Tier 2 barcodes, which are multi-colored squares arranged in a rectangular pattern for added security. Those are still 2D barcodes.
Detailed explanation-3: -Well, the QR – which stands for “quick response” – code is basically a barcode on steroids. While the barcode holds information horizontally, the QR code does so both horizontally and vertically. This enables the QR code to hold over a hundred times more information.
