I love how this person researched this by reading the “lucky” words in a foreign language version, when there is an option to read it in 23 different languages including english.

Edit: the document this article is based on has no mention of QR codes, atms, banks, or currencies, and nothing about vaccines being or becoming mandatory.

It seems to be about standardizing vaccine status documentation across the EU. Kind of like how we all get the same CDC card across the US.
