Essentially, yes. Revelation in the Bible prophecies talk about an end time "mark" received in the hand or the forehead, without which one will not be able to buy or sell. It's basically a membership card into a Godless society, and once accepted invalidates one for Salvation permanently. It makes sense that it would include Mastercard and some vaccine record/contact tracer info in it. I believe it will alter the DNA of the wearer in such a way that God will strike them from the Book of Life.
