"A QR code, or quick-response code, looks kind of like a standard barcode, but its complicated matrix of black and white squares gives it a lot more storage capacity.
From now on, this will be the way South Korea keeps track of people visiting places where there's a higher risk of infection."
Visitors will download a QR provider app like Naver.
Once they fill out their personal details, an instant QR code is generated.
There, your name, phone number, and the time you enter the place are automatically recorded.
The venue will scan the code to send the data for internet storage.
Due to privacy concerns, the information will be divided between the QR provider and a public institution, and will only be recombined for contact tracing during outbreaks.
All data will be deleted after four weeks.
This electronic entry log is currently undergoing a one-week trial in 19 selected facilities in the capital area.
But it will be adopted nationwide starting from June 10th.
And from then, it will become mandatory for places with a high risk of infection, including bars, nightclubs, singing rooms, and fitness classes like Zumba and spinning sessions.
Other venues like churches and movie theaters will also be recommended to use the QR codes.
The QR code-based entry logs first emerged as a tool to better track visitors and contain cluster infections,.. after some visitors to virus-hit clubs in Itaewon had written their information inaccurately.
