Quick Response (QR) Code

A Quick Response (QR) Code is a type of barcode that can be read by a digital device and which stores information. A quick response code, also called a QR code, is most frequently used to track information about products and is often frequently used in marketing and advertising campaigns. QR codes consist of black squares arranged in a grid (matrix) on a white background. QR code readers can extract data from the patterns that are present in the QR code matrix. QR codes are considered an advancement from older, two-dimensional barcodes.
