With the current large-scale cross-provincial turnout of workers returning to work and production, the pressure on epidemic prevention and control has increased. With the support of CETC Cloud, Umetrip has launched an emergency operation and the QR code for "One Network for All" (hereinafter referred to as "QR Code") function on APP, providing risk inquiry service to millions of registered users, offering solutions with technology and innovation to the business, supporting relevant departments with in-time epidemic monitoring, and assist the national epidemic prevention and joint control work.

Joint-developed by National Ministries and CETC, relying on the data released by the National Risk Population Perception Big Data Center, "One Network for All" big data analysis system for Epidemic Prevention & Control and Resumption of Work & Production can generate "QR Code". Users can link the data source within the platform to generate the safe reliable code. 

The "QR Code" received by users on the Umetrip app is divided into four colors: red, orange, yellow, and green. Green means the holder can go to work and go out as usual, and those who hold the yellow, orange, and red code need to be quarantined and require treatment. It is a code that can cover all scenes during epidemic prevention and control, a code can be recognized and traverse the entire nation.
