In order to ease foreign travel and reduce the risk of contamination, an increasing number of countries are adopting COVID vaccine passports, and South Korea is working hard to ensure that it is not left behind.

Vaccine passports will be sent to South Koreans in the near future.


A vaccine passport will be launched in April, according to South Korean Prime Minister Chung Sye-Kyun. Blockchain passports continue to stir up debate all over the world.

According to Chung, the passports would favor South Koreans at home as well. He said the vaccine passport would enable people that have already received the vaccine to restore their daily lives at a meeting for cross-agency COVID reaction.

The South Korean government created the Green Pass, which uses blockchain technology to fight identity fraud. In other countries, the framework may not allow personal data to be stored and can be used to check the status of COVID vaccination, Chung said.

So far about 77,000 South Koreans have taken the COVID-19 vaccine. On Wednesday, 551 new COVID cases were reported. By June this year, the South Korea nation hopes to have vaccinated about 12 million citizens.

The rise in vaccine passports


Brazil is another country that has deployed blockchain to monitor COVID vaccination. IBM has developed a blockchain-based information security system for New York referred to as the Excelsior Pass.

The Pass should be used to validate COVID vaccination or any other appropriate tests prerequisite for cross-border travel, according to New York authorities. A similar technology has already been implemented by the Chinese government, and the EU plans to do so by June. The International Air Transport Association is focusing on building an application, Travel Pass. This is likely to become the norm for international travel in the near future.

The definition of vaccine passports has been marred by controversy, especially in the United States. Kristi Noem, Governor of South Dakota, referred to it as an un-American notion.
