China using health tracking mobile system to curtail the spread of coronavirus

Alibaba and Tencent have introduced a health code system using QR codes to monitor citizens' health status as part of efforts to control the coronavirus spread. Launched by Alipay on February 11th, the system requires Chinese nationals to input personal information and travel history. After verification, citizens receive a color-coded QR code indicating their health status: green for safe, yellow for contact with a sick person, and red for restricted movement. Businesses in China are using these codes to verify health status before allowing entry.
