Yeah, basically an ID card that verifies that you have received the Covid vaccine. In a perfect world this could be a good thing. Things like live shows, festivals, bars and clubs, would become possible again as long as everyone's card gets checked at the door. On the other hand though, if your vaccination program is deliberately racist like it is in Israel (a program which leftists have legitimately referred to as vaccine apartheid), then vaccine passports could become a very simple way of denying public services to Palestinians.

Of course, that's not what this crowd appears to be protesting.
