QR Code

QR Code (abbreviated from Quick Response Code) is the trademark for a type of matrix barcode - or two-dimensional barcode, as opposed by the familiar one-dimensional style characterised by bars of varying thickness and spacing. Originally designed for the Japanese automotive industry, the QR Code system has become widely popular due to its fast readability and greater storage capacity compared to standard barcodes. Applications range from product-tracking, item identification, time tracking, document management, general marketing, and much more.

A QR code consists of black modules (square dots) arranged in a square grid on a white background, which can be read by an imaging device (such as a camera) and processed using special error-correction techniques until the image can be appropriately interpreted; data is then extracted from patterns present in both horizontal and vertical components of the image.
