Yep print it out or show it on your phone. At least that's the theory. Bulgaria is the only place Ive seen so far who will accept them*. Back in the UK just south of the border NHS Englands certificates have a QR code which you can scan to verify the details on the certificate on an NHS website. Your fake certificates could easily take you to fake but official looking website. It's worth noting that there is the same issue with validating the authenticity of fit to fly PCR test results. There are literally thousands of test providers around the world all producing their own certificates. Given the expenses of the tests and the easiness to produce something vaguely official looking there is a big market for fake PCR results. But people have been caught and as it is fraud the penalties are quite heavy. https://www.gov.uk/foreign-travel-advice/bulgaria/entry-requirements https://www.gov.uk/foreign-travel-advice/bulgaria/entry-requ...
