QR code is also called two-dimensional barcode. The common QR code is QR Code. QR stands for Quick Response. It is a very popular encoding method on mobile devices in recent years. It is much better than traditional Bar Code barcodes can store more information and represent more data types.

Two-dimensional bar code/QR code (2-dimensional bar code) is a black and white symbol that records data distributed on a plane (in a two-dimensional direction) using a certain geometric figure according to certain rules. Graphics of information; in coding, the concept of "0" and "1" bit streams that form the basis of the computer's internal logic is cleverly used, and several geometric shapes corresponding to binary are used to represent text numerical information, through image input devices Or photoelectric scanning equipment automatically reads to realize automatic information processing: it has some unique features of barcode technology: each code system has its own specific character set; each character occupies a certain width; it has certain verification functions, etc. . At the same time, it also has the function of automatically identifying different lines of information and processing graphics rotation change points.

On August 3, 2016, the Payment and Clearing Association issued the "Barcode Payment Business Specifications" (Draft for Comments) to payment institutions. The draft clearly pointed out the security standards that payment institutions need to follow when conducting barcode services. This is the first time the central bank has officially recognized the status of QR code payment since it stopped QR code payment in 2014.

China’s research on QR code technology began in 1993. China Article Coding Center has conducted translation and tracking research on the technical specifications of several commonly used QR codes PDF417, QRCCode, Data Matrix, Maxi Code, Code 49, Code 16K, and Code One. With the continuous improvement of China's market economy and the rapid development of information technology, domestic demand for the new technology of QR codes is increasing day by day. With the strong support of the former State Administration of Quality and Technical Supervision and relevant national departments, the China Article Coding Center has continued to conduct in-depth research on QR code technology. On the basis of digesting relevant foreign technical information, two national standards for QR codes were formulated: QR code grid matrix code (SJ/T 11349-2006) and QR code compact matrix code (SJ/T 11350-2006) ), thus greatly promoting the research and development of QR codes with independent intellectual property rights technology in China.
