South Korea to use QR codes for entering 'high-risk areas'

South Korea will require facilities deemed to be high-risk of spreading COVID-19 to install QR code readers. Places where multiple people gather around indoors, such as fitness centres, clubs, and karaoke bars, will be subject to the requirement, the Korea Centers for Disease Prevention and Control (KCDC) said. Prior to this announcement, South Korea had already required for those in government-mandated quarantine to wear electronic wristbands.
