The blockchain-based contact tracing system Jeju Safety Code will connect to South Korea’s “quarantine pass” system this month.

Media outlet Jeju Today reports that quarantine authorities on Jeju Island are working to get things connected by Dec. 22.

Residents of South Korea must now show a “quarantine pass” — digital proof that you’ve been vaccinated — to enter restaurants, cafes, bars, gyms, movie theaters and other public places.

Jointly developed by ICONLOOP and Jeju’s provincial government, Jeju Safety Code is the most popular contact tracing solution in Jeju Island, South Korea’s most popular holiday destination with 15 million visitors.

Fun Fact: the Seoul-Jeju route was the world’s busiest in 2019 with 85,000 flights over the year from eight different airlines.

About 50,000 multi-use facilities and 2 million people use Jeju Safety Code.

Simple to use, the solution offers a very nifty real-world use case of blockchain technology, and DID in particular:

To use the Jeju Safety Code app, visitors scan a QR code at a business or tourist destination. Business owners can place QR codes throughout their facilities, allowing people to check in without congregating or forming a line. Users do not need to sign up for an account to check in. When a visitor checks in, their location is authenticated, without the business needing to store any of their personal information.”

Last week, ICONLOOP also announced that MyID platform ZZEUNG had launched a COVID-19 vaccination certification service.

That service also works with Jeju Safety Code, though the new service apparently allows you to get your vaccination info within the Jeju Safety Code app itself.
