I have heard about it; also, welcome to the site! This topic might be better off over in the Conspiracy or News sections, but whatever.
There are actually a lot of digital passport/health credential agendas going on in nations all over the Earth right now. Over 21 US states are working on a "vaccine passport" / health credential and many nations, including Sweden, Austria, and a whole host of others. Actually, according to this website, it appears that finding a country which does NOT use such a system for travel now is getting rarer and rarer:

Scripturally, we can see that this likely is going to be tied into the eventual Mark of the Beast system, which will likely include a digital financial system, health passport, identity/tracking credential, and perhaps other systems including drug dispensing microchips (which already exist) in a single implantable package.
For this reason, and for reasons of personal liberty, I am now (since the COVID plandemic) an anti-vaxxer and will not get any kind of vaccine or implant no matter what, even if they threaten me with death.
I was born a free human being under old America, set fully at liberty through salvation in Christ, and so help me God I will DIE FREE.
