Beijing rolls out colour-coded QR system for coronavirus tracking

Beijing has joined a national initiative to assign residents coloured QR codes that determine whether they have to be quarantined, despite concerns of mislabelling and privacy leaks. The QR code system, launched through Ant Financial’s Alipay in Hangzhou on February 11, assigns users one of three coloured QR codes – green, yellow and red. he system, which has been rolled out in more than 100 cities across the country, has been criticised for a lack of transparency and potential mislabelling.
