Mandatory QR code - based registration at entertainment facilities to be effective this week SEOUL , June 9 ( Yonhap ) -- QR code - based registration of visitors at bars , clubs and other entertainment facilities across the country will be mandatory from Wednesday as part of the country ' s efforts to stem the spread of the new coronavirus , health authorities said Tuesday . Such facilities in the nation are required to use smartphone QR code - based entry logs for all visitors to keep records of their personal details . Since early this month , the country has enforced QR code - based entry logs at such facilities in the greater Seoul and some selected cities in its latest efforts to track and contain the new coronavirus . Visitors to the facilities have to get an one - time QR code via smartphone apps and submit it to the venue . The venue manager then scans the code and include it in a digital customer register . The mandatory measure comes as cluster infections traced to nightclubs and bars in the trendy Itaewon region of Seoul swelled in and around the capital city . As of Monday , a total of 274 COVID - 19 cases have been linked to Itaewon . Health authorities will conduct on - site inspections to make certain businesses comply with the toughened guidelines , with those that fail to meet requirements to be slapped with a fine of up to 3 million won ( US $ 2 , 500 ) or ordered to suspend operations . Besides bars and clubs , the government is moving to encourage religious facilities , movie theaters , hospitals and libraries to adopt the QR code logs going forward .
