With the requirements of modern production, the performance of today's variable data QR code inkjet printers is becoming higher and higher in terms of intelligence, variable, recognizable, and Internet. With the QR code, Internet and smart phone (barcode gun) ) There are more and more applications in anti-counterfeiting and logistics automation production. Our company has launched a computer two-dimensional code inkjet printer, and can provide two-dimensional code (one-dimensional bar code) and Internet and smart phone (barcode gun) and Two-dimensional code inkjet printer solutions. The variable data QR code printer can spray garbled codes, EXCEL forms, TXT text, pictures, etc.; it can be connected to two-dimensional equipment such as: equipment for measuring capacitance value, equipment for measuring the brightness of LED lights and measuring the flatness of mobile phone glass, Equipment such as transmittance and hardness. Based on the data entered above, a QR code can be formed by writing to the EXCEL database plus serial number, fixed code, garbled code, and operation code, sprayed on each corresponding product, and read the corresponding product with a smartphone After the QR code is transmitted to the cloud server, it is convenient for customers to query product information and identify the authenticity and anti-counterfeiting codes. Manufacturers can apply it to counterfeit and anti-counterfeiting, production process control and automated production, quality traceability, anti-fleeing goods, logistics, and QR codes. Warehouse management and other aspects. Multi-function, high precision, high photo, long life, food traceability greatly improves work efficiency, and realizes the filtering of counterfeit and inferior products. Through the statistics of food information, the flow distribution of a certain food within the city can be counted. The food is targeted, avoiding the previous drag-net-type investigation, and saving a lot of manpower and material resources. At the same time, the counterfeit and inferior products are contained and filtered out of the market gate to the greatest extent, purifying the market.
