SEOUL--South Korea has reported 50 new cases of COVID-19 as officials began requiring nightclubs, karaoke rooms and gyms to register their customers with smartphone QR codes so they could be easily located when needed.

The figures from the Korea Centers for Disease Control and Prevention on Wednesday brought national totals to 11,902 cases and 276 deaths. At least 41 of the cases were reported from the Seoul metropolitan area, where officials have struggled to trace transmissions linked to entertainment venues, church gatherings and low-income workers who couldn’t afford to stay home.

Since late May, the country has been reporting around 30 to 50 new cases per day, a resurgence that has threatened to erase some of the hard-won gains against the virus as people begin to ease on distancing.

The nationwide requirement of QR codes at “high-risk” venues come after a weeklong trial run in the cities of Seoul, Incheon and Daejeon, where some 300 businesses used an app developed by internet company Naver to collect the information of some 6,000 customers. The government is also encouraging churches, libraries, hospitals and movie theaters to voluntarily adopt the technology.

South Korea has aggressively mobilized technological tools to trace contacts and enforce quarantines, with an infectious disease law strengthened after a 2015 outbreak of a different coronavirus, Middle East Respiratory Syndrome or MERS, allowing authorities quick access to cellphone data, credit-card records and surveillance camera footage.

But critics say privacy is being sacrificed for epidemiological gains and that it’s excessive to preemptively collect personal details through smartphone QR codes when there are no clear grounds to consider the individuals as potential virus carriers.

Prime Minster Chung Sye-kyun during a virus meeting on Wednesday tried to downplay the privacy concerns, saying that the information collected through the apps will be destroyed after a certain period.

CHINA REPORTS 3 CASES: China says its three latest cases of coronavirus infection were brought from outside the country. No new deaths were reported Wednesday and just 55 people remain in treatment for COVID-19, while another 157 were being monitored in isolation for showing signs of having the virus or having tested positive for it without showing symptoms.

PROTEST OF NISSAN CLOSINGS: Disgruntled Nissan workers marched Tuesday evening in Barcelona in their latest protest of the Japanese company’s decision to shut its manufacturing plants in northeastern Spain. The closures will bring some 3,000 job losses. The company’s head of European operations said the closure was unavoidable as Nissan redrew its global business strategy. “We see no clear alternative to the closure and that’s the path we’re taking,” Gianluca de Ficchy said in an interview with El Pais. “The process has already begun.”
