Ride-hailing platforms in China are helping local authorities track commuters who might have been in close contact with those diagnosed with the novel coronavirus with real-name registration systems for public transport in some cities.
The systems, backed up by tech companies including Meituan Dianping and Dida Chuxing, require commuters to provide their personal information by scanning QR codes with their mobile phones before taking buses, trains and taxis. Those who refuse to register will not be allowed on public transport.
