Beijing introduces coloured QR code system to track coronavirus

According to a report, China’s capital city Beijing joined more than 100 Chinese cities that assigned their residents with coloured QR codes in attempt to track and contain the spread of coronavirus. The QR code system developed by Ant Financial’s Alipay has been launched amid concerns related to accuracy and privacy. Users of Alipay and WeChat can access their codes by inputting their name, national identity number, and registering with facial recognition. Only those with a green code are allowed to travel in the city freely while those with yellow and red codes are required to quarantine themselves at home or subject to supervised quarantine. According to Pan Feng, deputy chief of the Beijing Municipal Bureau of Economy and Information Technology, the system will allow users to check the QR codes of others by entering their ID numbers.
