I've done all these things, and all of them are a miniscule % of my buying and selling. Revelation speaks of a time when the everyday life of buying and selling is restricted to mark.
Correct. The Mark of the Beast has not yet begun. However, identification, methods already in place, electronic access/pathways, restrictions, etc. are paving the way.
One such method paying the way is India collecting retina scans and fingerprints of all their 1.2 billion people. Been going on for years. They have no idea the Tribulation is coming.

As I’ve mentioned before, the Greek word is “charagma” (hat tip to Dr. Ed Hindson) - it is used for some sort of tattoo that will coincide with the False Prophet enforcing this systems; just after the Antichrist performs the Abomination that Causes Desolation.
The Tribulation (nor the Great Tribulation referenced in the preceding paragraph) have not yet begun. Doesn’t seem too far off, though, some days.
