Now that various jurisdictions around the world have their own versions of covid passes, is there a platform that can verify more than one of them?The types I’m currently aware of that have significant adoption are:EU Covid pass (digital green certificate)
NHS (UK) vaccination certificate
SMART health cards (US various)
Excelsior pass (NY)There are probably others.Most seem to be QR codes with signatures over various claims. I don’t see why a single app couldn’t verify all of them if the public key registries are public.If such a platform doesn’t yet exist, is anyone working on one? It sounds like the Linux Foundation Public Health people are investigating things from a policy perspective.
