On April 2, the QR Code for "One Network for All" Big Data Analysis System (hereinafter referred to as "QR code") provided by CETC was officially launched on DiDi. DiDi drivers obtain QR code to work in dozens of cities in China, including Beijing, Shanghai, Guangzhou, Shenzhen and Nanjing. When passengers use Didi's ride-hailing service, they would receive a gentle reminder saying "The driver has obtained the safe green QR code provided by CETC, please feel free to take the car". Passengers can also check the color of the driver's QR code on the "Disinfection Registration Management" page of DiDi to ensure being far away from COVID-19 and avoiding travel risks.

Zhang Bo, co-founder and CTO of DiDi, CEO of DiDi Autonomous Driving Company, said that the cooperation with CETC is a typical case of accurate data application in helping orderly production. QR code will assist DiDi in providing safer travel services to the public, accelerate work and life resumption, and contribute to economic development.
