Sunson's certificate-making technology has created a number of firsts in the field of certificate-making research, production and application: the first PVC card-type certificate, the first Chinese second-generation ID card, the first external chip social security card, the first rewritable card-type Certificates, the first self-service forensics equipment... Innovative constant temperature lamination, molecular bonding and other certificate making technologies lead the world, research and formulate legal identity document standards and processes, so far, using our developed systems and equipment to produce high-quality anti-counterfeiting, high-quality products in the world There are more than 2 billion durable legal documents. In 2011, Shenzhen hosted the 26th Universiade. We produced more than 440,000 certificates, 95 layouts and 337 styles, all of which were the highest ever. In 2019, we pioneered the use of cutting-edge technologies such as radar and structured light integrated ranging, far-infrared and millimeter-wave integrated imaging, etc., to complete the overall design and implementation of the drive-through inspection project for passenger car passengers at the port. research and development tasks. In 2020, we innovatively applied self-developed technologies such as iris recognition and long-range targeted RFID to complete the design and development tasks of the third-generation customs clearance mode for non-inductive inspection at ports, changing the existing customs clearance experience.
