Health authorities will use CCTV footage, credit card transaction data, travel information, and location data to keep tabs on patients.
Using the smart city data bank combined with artificial intelligence, it would take an official roughly 10 minutes to figure out where a patient traveled over the course of the day,
Reuters reports.
New arrivals also have to download a government smartphone app that tracks their location and asks them to report any symptoms, according to
Reuters. Even those without symptoms are forced to self-quarantine for two weeks, after which the app displays a message saying they're allowed to delete the app from their phone.
