Korean company launches mobile application for COVID-19 free-pass

Pass&Go has been developed by GG56

Pass&Go, a mobile application for COVID-19 free-pass, has been developed by GG56, a blockchain company in the Republic of Korea. Pass&Go allows users to securely store and manage their COVID-19 test results and vaccination status and creates temporary digital passes for those who have tested negative or have developed COVID-19 antibodies after vaccinations. Pass&Go provides certificates for the COVID-19 test results from hospitals or certified medical institutions but also from home testing kits which some European countries have been authorised to use. The application also supports creating digital credentials for various vaccinations and to manage other infectious diseases.


Pass&Go uses the BTour Chain blockchain to preserve privacy such as personal information and health status including COVID-19 test results and vaccination records. All data including personal information and medical history will be encrypted and stored in the blocks, and thus safely protected from leakage via our blockchain technology. The app generates a health certificate or passes in the form of a QR code only for those confirmed without COVID-19 infection or with COVID-19 antibodies, and the users can use the QR credentials to enter various places such as restaurants, hotels, stadiums, offices, and even countries. Pass&Go is an integrated infectious disease and vaccination management platform where users can monitor and track their vaccination history. The involvement of Pass&Go with blockchain technology is a result of many tech giants and public companies investing in Bitcoin and other Blockchain-related businesses.

GG56 has signed MOAs with several South Korea’s leading biotechnology companies such as MiCo BioMed Co and Sugentech etc. whose COVID-19 testing products have been in use in many parts of the world. Also, GG56 is discussing the introduction of the service—Pass&Go with some provincial governments in South Korea, as well as, more than 20 countries including Romania, Morocco, the Philippines, and Middle Eastern countries. It is said that discussions over the introduction of Pass&Go are underway with renowned international organisations leading their respective fields across the world. Also, GG56 announced that they will distribute the service free of charge for all over the world, hoping to contribute to the fast recovery from the COVID-19 crisis.
