A major contact tracing app in China is going offline. It marks a big step in loosing COVID-19 restrictions, but it’s far from the only health tracking method used during the pandemic.
The app is called “mobile itinerary card.” It launched in February 2020, almost immediately after the pandemic broke out in Wuhan, China.
Operating via smart phones, the app can trace back where a phone owner has been in the last 7 to 14 days. When an app user enters an area designated by authorities as posing “high-risk” of infection—the app would changes the user’s status color from green to yellow or red.
Both of those statues limit the phone owner’s access to public spaces and transportation.
