Singapore will make some incoming travelers wear an electronic monitoring device to ensure that they comply with coronavirus quarantines as the city-state gradually reopens its borders, authorities said Monday.

From August 11, the devices will be given to incoming travelers, including citizens and residents, from a select group of countries who will be allowed to isolate at home rather than at a state-appointed facility.

Similar measures using electronic wristbands to track peoples' movements during quarantine have been used in Hong Kong and South Korea.
