A Brief History of QR Code
The QR code system was invented in 1994 by Japanese car manufacturer Denso Wave. The original alternating square design proposed by a research team led by Masahiro Hara was influenced by the black and white chess pieces on the Go board; by applying the least used ratio of black and white areas (1:1:3:1:1) to an optical scanner The printed matter cannot be misidentified, and the position detection pattern is found and determined. The functional purpose of the QR code system is to facilitate tracking of the type and quantity of auto parts by replacing the individually scanned barcode labels on each box of auto parts with a single label containing the data for each label. The square configuration of the QR code system integrates data from various barcode labels with kanji, kana and alphanumeric codes printed on a single label
A QR code consists of black squares arranged in a square grid on a white background, includes some reference marks that can be read by an imaging device (such as a camera), and is processed using Reed-Solomon error correction until the image can be adequately rendered and interpreted . The required data is then extracted from the patterns present in the horizontal and vertical components of the QR image.
