SINGAPORE -- From the early days of the coronavirus crisis, contact tracing has been a core element of Singapore's containment strategy. Now the city-state is raising its tracking game.
Come Tuesday, visiting a shopping mall, entering a factory or even getting a haircut will entail a mandatory online check-in. This system, called SafeEntry, will be introduced gradually in taxis hailed on the street and other places as well, as the country begins to reopen.
