Recently, the Prime Minister of South Korea, Chung Sye-Kyun, ad that the Government will make available to the citizens of that country a kind of "vaccine passports" based on blockchain, which can be accessed through smartphones, which will mitigate the risk of infections in cross-border travel, as indicated by Cointelegraph.
Indeed, Chung Sye-Kyun points out that people will be able to experience a feeling of return to normality thanks to the vaccine passport or green card system, in response to the health crisis resulting from the Covid-19 pandemic. Likewise, the Government of South Korea has been applying the technology blockchain in other services available to citizens, such as personal information verification systems, which provides greater security against identity theft in that country, according to the aforementioned portal.
Likewise, China and the European Union have plans to incorporate a Travel pass, which would serve in the same way as the "vaccine passport." Saying Travel pass would be launching in June of this year approximately, according to the portal NewsTalk.
