2D code traceability, a relatively unpopular but also "hot" word, "cold" means that many people don't know what it is, and "hot" means that this is a popular trend and a state-supported project. With the continuous development of the information age and the era of big data, the application of 2D codes is also constantly breaking through technological innovation. It should be said that the most important thing is the traceability function of 2D codes. What is the role of QR code traceability?

Traceable production information runs through the traceability of product quality. Food safety traceability is one thing people pay more attention to in today's era, which is product quality! food safety! It is related to the vital interests of every consumer, as consumers, they have the right to know. Qr code product traceability Qr code, scan the Qr code by mobile phone, or scan the Qr code through the query terminal, the traceability can be queried from the raw materials of the product, to the production, transportation, sales and other links, and according to the product attributes, there are product quality inspection reports, a Code one information chain, in order to ensure the quality of the products, consumers can buy with confidence, rest assured, and eat with confidence.

Quality responsibility can be traced back to the product source QR code, which contains the processing and production information of each link, such as: operator, operation time, operator, person in charge, quantity, inspection and other information. Once a product problem occurs, it can be traced back to the whole process of product circulation, from production to processing, from warehousing to warehousing, and then to distributors at all levels, to achieve full traceability, and fundamentally achieve quality traceability and accountability.

Anti-counterfeiting and anti-counterfeiting verification QR code traceability In the above process, product traceability information is the information of the entire industry chain, which is the collection of blockchain information. All product-related information can be traced back to cloud storage through the QR code. For example, meat products involve such inspection and quarantine, transportation, transportation information and transportation quarantine, slaughtering, slaughtering, etc., there are several slaughtering, slaughtering inspection and quarantine links, and each link must have real certificates, as well as time, The information of the location and the person in charge can prevent fraud to a certain extent, and the QR code traceability system has its own anti-counterfeiting code, the code is not fake, and the fake is not fake, because the traceability can check the entire network, encrypt and encode information multiple times, and Equipped with anti-counterfeiting verification system. Really promote high-quality and honest management, and prevent fake and shoddy products from entering the market.

It is convenient for management and prevents QR codes from product traceability based on channels, so as to achieve one code for one thing, each code is the unique ID card information of a product, which can be used for product production, warehousing, logistics and transportation, agency, sales, user management, etc. , Through the application of the 2D code traceability system, the management efficiency of the enterprise has been improved several times, saying goodbye to the traditional paper records. Now only scanning the 2D code can realize the editing of product information and warehouse-to-warehouse management, and the information is clearer , effectively prevent the movement of goods, shortage of goods and missing goods. 2D code scanning is a popular trend in today's society, especially young people, who are accustomed to scanning 2D codes to view, conforming to social trends is an inevitable requirement for enterprise development. Through the ingenious combination of 2D code traceability system and marketing methods, Realize the true charm of IoT.
