Just read that Israel has Green Passes to prove that you are vaccinated so you can have access to normal society. Reminds me of when I was in South America and a fair-haired Argentine called “Gringo” told me the term came from the fact that border-crossers with a green card got a “go.” The guard would say, “Green? Go.” and the non-English speakers rejected would only hear the guard say to someone “Gringo” and the gringo would go north. Who knows about that, but looks pretty certain that in Israel–for starters–“Green Go” is a reality in what has become “permission living” on steroids.
Here’s an article on Israel as the frontrunner of this: https://www.technologyreview.com/2021/03/01/1020154/israels-green-pass-is-an-early-vision-of-how-we-leave-lockdown/
