Korea deploys QR-code system nationwide

South Korea is adding yet more high technology to its anti-virus arsenal as it continues the national battle against Covid-19. A QR code-based entry log system was made mandatory at some 80,000 facilities nationwide, and the country is considering using a similar system for baseball stadia.

The country has, over the last two months, seen clusters arise in nightclubs, call centers, distribution centers, churches, cram schools, a dance club and a table tennis club.
