Yes, that's what they said (the visa number of the credit card). But the twist as far as I can interpret and if we quote the biblical verse: "and that no man may buy or sell, save he that hath the mark, or the name of the beast, or the number of his name." We are already seeing this with sanitary passports (visas). If you don't have the mark (vaccine - passport) you can't travel, you can't buy, you can't sell.
Now all this technology can be integrated into a single monolithic control system where your vaccination status, health passport and bank account are added. You also need a complete and fast coverage for the handling of this data. (most likely 5G antennas).
The closest example is the Chinese social credit system.
The social credit system in China is currently just a trial phase, apparently. This is borne out by the details in the Wikipedia article, and also corroborated by this short RT documentary:
The 'OMG! Chi-Coms!' narrative in Western media looks like classical cynical projection of the 'national shadow'. Just like American governments or NATO raising alarm bells about terrorism. Projecting totalitarianism or terrorism outwards onto a 'national Other' functions to hide these operations by the home nation. Safe in the knowledge that 'we're much better than they are', the public is willing to submit to even more 'forever-war' military spending and domestic social decay and whatever other 'delightful' schemes the local elites have planned.
It's a curious day when, in terms of social control, things look far worse in Australia vs. China.
So China gets to be either a testing-ground for the Mark of the Beast, or a punching-bag (or both). Meanwhile an 'alphabet soup' of institutions based in the West are pushing the Great Reset, a fact which far too many people in the West are too hypnotized to see.
