Anti-counterfeiting traceability, that is, information traceability identification (including two-dimensional code, bar code, RFID) determines that it plays an important role in anti-counterfeiting traceability, and has become an essential tool for anti-counterfeiting traceability in the current market. The two-dimensional code printed by users in need through the product traceability inkjet printer can achieve the coexistence of anti-counterfeiting and traceability functions. Information storage, process control, information encryption, and verification and reading of information are all achieved through the two-dimensional code, satisfying enterprises and consumers With regard to product anti-counterfeiting and traceability requirements, products are assigned a unique two-dimensional code as an anti-counterfeiting ID card through professional machinery and equipment. At present, product traceability in the market uses product traceability inkjet printers to give each product a unique identification code and bind it to the product, which clearly records the data information of each link of the product from production to warehousing to the final logistics and distribution, so that logistics can be traced completely. It becomes possible. Through the powerful data processing function of the third-party system, the detailed information trend of the circulating products can be inquired; through the product anti-counterfeiting traceability inkjet printer, the product transformation and the installation of the inkjet equipment system can be passed The system queries the specific batch, production time, production team, circulation area and other information of the product, so as to trace the cause and realize accurate recall processing. The development of inkjet printers, first of all, through technological innovations, to bring technological innovations, to trace products to a certain degree, and to improve the credibility of shopping. This is the general trend. A direct example is variable QR code marketing. It can realize the anti-counterfeiting function by scanning the code, and the two-dimensional code can distinguish the authenticity. In order to resist the circulation of counterfeit goods, the premise is to have a product traceability inkjet printer as the foundation, so as to realize the accurate recording and traceability of each process.
