South Korea to test QR codes at nightclubs, eateries and cinemas

South Korea plans to test quick response (QR) code-based entry logs at nightclubs, eateries, cinemas and even churches in its latest efforts to track the new coronavirus. Under the plan, the government plans to test the digital entry registers at 19 facilities in Seoul, Incheon and Daejeon from Monday to Sunday before expanding the system across the country. Visitors to the facilities would have to get an one-time QR code via smartphone apps and submit it to the venue.
