With the rapid advancement of technology today, two-dimensional codes have been ubiquitous in people's daily life. The two major domestic mobile payments, led by Alipay and WeChat, have combined the two to form a new generation of wireless payment solutions, making the payment experience faster and easier. At present, QR codes are also widely used in re-retailing, high-tech, transportation, tracking and tracing. and other industries. In the application system of general commodity barcodes, one-dimensional codes (barcodes) are first used, which consist of multiple black bars and blanks with different widths. After decades of development, one-dimensional codes have begun to expose many shortcomings, such as small data capacity, only letters and numbers, and relatively large barcodes. If the barcode is damaged, it cannot be read, etc. In order to make up for these shortcomings, people began to look for better alternatives at this time. Denso is an independent company from Toyota Motor Corporation of Japan. Its main business is to provide auto parts and accessories for Toyota. However, the information contained in the spare parts of the car is complex, and the information capacity of the traditional barcode is too small. It can only store 29 Japanese characters, and it is impossible to accurately distinguish these products. How to mark more product information on the part label has become a problem that Japan Denso needs to overcome urgently. In fact, the principle of barcode is the same as that of the entire Internet civilization including computers. It is binary. Several binary corresponding geometric shapes are used to represent text and numerical information, which can be automatically read by image input equipment or photoelectric scanning equipment to realize automatic information processing. Teng Hongyuan of DensoWave Company led the team for two years of research, and upgraded the barcode on the label to a two-dimensional code. The information originally stored in strips has become one small square after another. In 1994, Japan's Denso Corporation (Decso) officially announced the public acceptance of a QR Code, the full name of which is 'Quick Response', which is a quick response code. It has the advantages of large information capacity, high reliability, capable of representing various text information such as Chinese characters and images, and strong confidentiality and anti-counterfeiting, which are possessed by one-dimensional codes and other two-dimensional codes. Features of QR code 1. High-density coding and large information capacity. 2, the coding range is wide. 3. Strong fault tolerance and error correction function. 4. The decoding reliability is high. 5. Encryption measures can be introduced. 6. Low cost, easy to make and durable. The earliest prototype of the QR code made by the Teng Hongyuan team: the color blocks of different colors undertake different recording functions, which greatly improves the information capacity. Once the QR code was researched, it solved the problem of labeling information. It can store 5,000 Japanese characters, which is a 250-fold increase in information storage compared to the previous single barcode! On this basis, Denso also made the common black and white QR code today, which is the QR code we often scan now. A variety of code systems have been developed for QR code symbol representation technology, such as PDF417, QR Code, Code49, COde 16K, Code One, etc. The density of these two-dimensional codes has been greatly improved compared with the traditional one-dimensional codes. Although the QR code was invented by Denso, the founder Teng Hong felt that the QR Code could store so much information and had already exerted its maximum function. In fact, he gave up the patent fee for the daily use of the QR code. Demands! In 2011, due to the development of domestic Taobao, QR code payment was officially introduced into the Chinese market by Alipay, and on July 1 of that year, the mobile APP QR code payment service was officially launched to enter the domestic offline payment market. Xu Wei, the founder of Lingkong.com, also applied for the registration of the 'QR code scanning patent' and successively won the patent rights of 'method devices and mobile terminals using barcode images for communication' in China, the United States, Japan and the European Union. Such a big opportunity was seized by the Chinese people. When Western people are generally unfamiliar with QR codes and mobile payments, China's mobile payment application scene has exploded in popularity, and it is even called 'new'. One of the Four Great Inventions. In 2012, the coverage of the QR code of our pot was wider, and Alipay realized the function of bank card transfer and red envelopes through the QR code. Nowadays, Chinese people do not need to bring cash or bank cards when they go out. They can easily solve the payment problem with a mobile phone. Going forward, the market of QR codes in China is getting bigger and bigger. Scanning the QR codes on the goods will pop up relevant information. In large supermarkets and small supermarkets, you can see the QR code as soon as you go out. figure. By scanning the QR code on the shared bicycle, you can unlock and ride the bicycle, which saves all the complicated processes. Now, taking the bus, subway or even a plane can be perfectly solved by scanning the QR code. QR codes are also widely used in the tracking and tracing industry. Give the product one item and one code,Consumers can scan the QR code of the product to learn about all the production factors such as raw materials, suppliers, and production processes, as well as product flow information.
