Covid provided a massive boost for all of these kinds of systems. I say the cat is out of the bag. Just like when passports came to being “a thing” back in WW1. Before WW1 the British Empire convinced Belgium to drop the idea of passports. During WW1 governments across the world realised that using passports to control who can come to their country was easily sold to their citizens. 100 years later they are standardised across the planet. I can see the current trend of vaccine passports and the tracking in the same vein.
