COOV

Vaccination certificate app

COOV is a national COVID-19 vaccination digital certificate system by Korea Disease Control and Prevention Agency and Blockchain Labs. Paper certificates are vulnerable to forgery and not convenient to carry around all the time. So we created a mobile application with blockchain technology yet no complex UI. Users can set up the app in two minutes and follow directions using a single button to retrieve their current status. They can present this proof of vaccination upon visiting social or public venues. The international certificate is designed like a passport so that the users intuitively know when and how to use it.
