I, personally, have many reasons for being hesitant to put a chip in my person haha. Mark of the beast is not one of them. I'm not of the persuasion that the mark of the beast is talking about some future technology implemented by Antichrist. I'm not even of the persuasion that it has application beyond 70AD (though arguments of "double fulfillment are interesting). I wrote about this on a different post and I'll repost it here:
"[This perspective] arises from an erroneous eschatological reading of Revelation. Buying and selling, as well as the larger theme of being marked, is used throughout Revelation in connection with worship (v. 3:18, 5:9–10, 7:3–4, 13:16–17, 18:11–13). The mark of the beast is contrasted by the seal of God on the forehead. There is a lot more here to unpack but ultimately it is all making a spiritual point rather than painting a doomer end times situation."
