Many countries still require vaccinations, such as yellow fever – proof of which has to be presented at the check-in desk, entry visas, etc. These are often printed on paper and easy to fake. Having these all as verifiable digital credentials will reduce not just the risk of fraud at check-in, but also reduce friction, making the customer experience faster and better.
