Nowadays, two-dimensional codes are widely used in people's current lives, such as shopping, payment, and information acquisition, which are becoming more and more indispensable. At present, China has become the world's largest QR code application country, and it has been applied in many new areas such as bicycle sharing, mobile payment, and traceability system construction. Because of the popularity of QR codes and the demand for product packaging, large UV variable QR code inkjet printers have become very popular. We recommend suitable equipment for customers, which has significantly improved in all aspects, and the scope of application Get further expansion. First, the world is entering the era of the Internet of Things, and developed economies are promoting the development of intelligent manufacturing. The mechanical UV variable QR code inkjet printer is a device that gives the product or packaging a code mark. The inkjet printer is here. The data link is the core in the process, and the two-dimensional code is a very important technology for collecting and converging data. Two-dimensional code is a bar code format that is more advanced than one-dimensional code. Two-dimensional codes can store information in both horizontal and vertical directions. One-dimensional codes can only be composed of numbers and letters, while two-dimensional codes can store information such as Chinese characters, numbers and pictures, so the application fields of two-dimensional codes are much wider. In the new business model, it is necessary to hold an ID card with accuracy to a product, so that consumers can identify genuine products, and businesses can also fully understand the sales situation in time. With UV variable QR code inkjet printer as a brand-new automatic identification and information carrier technology, more and more people understand and recognize the reliability of the QR code. In the inkjet printer industry market, the inkjet printing requirements of QR codes can generally be met, so the wide application of QR codes is bound to contribute to the development of the inkjet printer market.
