A QR Code (Quick Response Code) is a type of matrix barcode first designed for the automotive industry in Japan. A QR code uses four standardized encoding modes (numeric, alphanumeric, byte/binary, and kanji) to store data.
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.
