QR code used to keep track of visitors to high-risk businesses in Seoul Updated: 2020-05-25 17:05:22 KST

Visitors to this PC cafe in Seoul's Seongdong-gu District are filling out their details electronically.

First, you open your camera and scan this QR code.
A link pops up that leads you to a site.
You must fill out your name, phone number, and answer several health-related questions to get an entrance number.
In less than a minute, your personal information and the time you've entered the place are automatically recorded and stored by the QR provider.

To visitors, this electronic system can be safer than the analogue method of writing down information on a piece of paper.

"I don't have to talk to the employee and touch the pen others used. So it reduces any potential risk."

"The QR code system is also more effective in keeping visitor's privacy because their personal information is not being shared with the businesses."

Seongdong-gu District has applied this high-tech system to other places with a high risk of infection, like PC cafes, singing rooms, and sports facilities.
It allows them to instantly trace people who visited a particular place at a particular time, which helps them respond swiftly to any outbreak.

"We can immediately message everyone on the list of visitors to tell them to stay home and get tested."

The official also said the system can actively restrict visitors' activities by making this "entry decline sign" pop up when they scan the QR code at other places.

For privacy concerns, the data expires after four weeks, and the district government can only access it if an outbreak occurs.
The central government announced on Sunday that it will require all night entertainment establishments to use this system.
