The difference now is that this information is being made digitally available outside of a personal health dossier. When traveling to African or South American countries, you have to show proof to a public immigration agent. I have an international vaccination passport, on paper, which has been 'good enough' to provide this proof. My health dossier is not publically accessible. Currently, this check is - looking at a piece of paper for the correct stamps, - perfomed by a public immigration officer, - upon entering a country. With this QR code, I now put this check into the hands of - any QR code 'reader' app, - on a Google or iOS platform, - which can be connected to the internet, - performed by private companies (venue/event/organizer) - upon entering a variety of locations.
