Tencent rolls out QR code that tracks potential Covid-19 carriers on public transportation
China has been using big data to stop the spread of the deadly coronavirus
As a result of the Covid-19 epidemic, Tencent is rolling out a QR code system on WeChat, China’s largest social network, to track people using public transportation. Passengers entering a bus, subway or taxi can submit their information through Tencent’s "ride registration code" and the system will synchronize their real names with the vehicle’s license plate, boarding time and other information. When a passenger is discovered to have been infected, other passengers who might have been exposed will get a message warning them.
