That’s novel, you managed to make a Revelation Chapter 13 thread fun & interesting to read.
Revelation 13
16He also forced everyone, small and great, rich and poor, free and slave, to receive a mark on his right hand or on his forehead, 17so that no one could buy or sell unless he had the mark, which is the name of the beast or the number of his name.
I’ve always thought that what John was seeing was people placing their right hand on a palm reader or putting their forehead on a retinal scanner.
If that is the case, then the “mark” itself would be cosmetic and taken only as a matter of pride in their rejection of Christ.
