China seeks help of tech giants to track coronavirus with QR codes

Alipay, the payment app operated by Alibaba's financial division Ant Financial, released a feature in collaboration with the government that assigns a coloured QR code representing the health of residents in Hangzhou.

Users in the city fill out an online form reporting their ID number, whether they have travelled outside Hangzhou recently, and any symptoms they might have that suggest an illness, such as fever or a heavy cough.
