This tech is troubling, partially because it will work, the question is what it will work for. I've worked in privacy for a long time, and these passport schemes are just an absolute attack on health information privacy legislation and they create the precise outcome the regulations were designed to prevent, which was a literal tyranical society that used arbitrary medical pretexts to privilege and disadvatage people politically and economically. This isn't just rhetoric either, we have decades of health information privacy legislation built around this principle. Every single new government tech in many countries needs to go through a privacy impact assessment to ensure it isn't a mechanism to do this specific thing, and I guarantee these technologies would not have survived one. Why should you give your vaccination status to anyone within the borders of a country, and what meaningful assurance does it provide to the pub/venue recieving it? Here is what it does not do: a) show you do not have a variant of a disease b) show you are not carrying a disease c) show you are or are not vulnerable to a disease or variants of it What does demonstrating this status signify? Perhaps I am missing something.
