On the prolonged COVID-19 situation, blockchain is attracting attention as a technological way to safely resume travel.

In order to safely resume overseas travel and tourism, governments, international organizations, and IT companies are vigorously developing vaccine passports. A vaccine passport will be able to provide the corona 19 test result. It can be used as a digital certificate that can prove personal immunity information such as whether or not. This can be used to simplify the immigration process.

While the travel industry was hit hard by the aftermath of Corona 19, the air travel industry is rushing to introduce blockchain-based digital and contactless solutions.

France Air France introduces a blockchain system that can check passengers’ personal and health information. The International Air Transport Association (IATA), referred to as the United Nations in the aviation industry, is working on a blockchain-based e-passport travel pass that indicates the status of the COVID-19 test vaccine.
