South Korean clubs will use QR codes to log visitors

South Korea will now require places like nightclubs and bars to use QR codes to log customers’ visits as part of its coronavirus contact tracing efforts. Those types of establishments will be required to use the app-based register to make it easier to track down potential COVID-19-infected patients. The deadly virus has infected more than 11,200 in South Korea and has killed 267 people in the East Asian country.
