What is a QR (Quick Response) Code
QR codes are popular due to their fast readability and greater storage capacity compared to standard barcodes. Applications include product tracking, item identification, time tracking, document management, and general marketing.
A QR code consists of black squares arranged in a square grid on a white background, which can be read by an imaging device such as a camera, and processed using Reed–Solomon error correction until the image can be properly interpreted. The required data is then extracted from patterns that are present in both horizontal and vertical components of the image.
