QR Code Generator with Python using just 5 lines of code
A QR code (quick response code) is a type of matrix barcode or two-dimensional barcode invented in 1994 by Japanese company Denso Wave. A QR code consists of black squares arranged in a square grid on a white background, including some fiducial markers, which can be read by an imaging device such as a camera, and processed using Reed–Solomon error correction until the image can be appropriately interpreted. The required data is then extracted from patterns that are present in both horizontal and vertical components of the image.
