A QR code, short for quick-response code, is a type of two-dimensional matrix barcode invented in 1994 by Masahiro Hara of the Japanese company Denso Wave for labelling automobile parts. It features white and black squares within a square grid featuring fiducial markers on the corners, readable by imaging devices like cameras, 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 the horizontal and the vertical components of the QR image.
A QR code is a square barcode made of black and white squares that was invented in 1994 to track car parts, and it can be read by cameras and smartphones. The code stores information in its pattern, which is extracted using special error-correction technology that allows the code to be readable even if it's partially damaged or unclear.
