In-reply-to > @fastidious I have somewhat of a problem with it BECAUSE it is a paper or a stupid and broken phone app - both of those things are unreliable. A paper gets wet and turns into mush and an app stops working when you need it the most or once you run out of the battery. this that you wrote “we live in the 21th century, so don’t tell me we don’t have the technology to link the certificate to the ID card, or another thing we already carry and give the people checking them some device that can check that” is what many people are against. They are afraid that will give governments too much power, when it comes to a centralised one. I don’t have a problem with it; the government already has a ton of information about me. Having that specific detail added to the existing pile is not the end of the world.
