I don't agree with this because the beast deceives people. When you deceive someone you don't tell them straight out what they are getting into. Emilio said it very correctly before that the mark of the beast is about following the commandments of the beasts rather than God's. While a physical mark might play some role the real focus is on the spiritual. If the devil keeps out focus on the physical he will easily get us to walk into his spiritual trap and accept the true mark of the beast. That is deception, not coming to your face and telling you exactly what is going on.
I've been reading this thread with great interest, so I thought I'd chime in.
I think that the mark is a real actual mark. And since the bible is clear that it's tied to commerce, this almost has to be either a chip or an RFID tag... anything that can be read at the point of sale to approve or deny the transaction.
I can also tell you that it's most likely not a bar code or any other kind of tattoo. The reason for this is that bar code scanners have enough of a hard time reading bar codes on paper. What if someone gets cut, or gets a sunburn. And tattoos fade. And lastly, far more information can be kept in an implantable chip, whereas a bar code can only hold a relatively short number.
RFID chips can also be read at a distance. This is great for crowd control. If there's a demonstration or a riot, just drive through with a reader and call people's names out over a loudspeaker as a warning, record everyone who showed up, fine everyone, etc.
And lastly, there was also a recent article about a saudi (iirc) man who filed for a patent in germany for an implantable chip that contains a cyanide capsule that can be administered remotely. Sounds like an ideal new world order device to me.
So I think it's a real actual mark. But also, I think taking the mark will require taking an oath. And after the midpoint of the tribulation, the one world religion will be all about worshiping the antichrist, the man, directly. And this is the real problem. It's the oath. But you can't have the mark without the oath. Maybe the chip even contains a recording of you taking the oath so there's no question.
I also agree that there will be deception involved, even maybe the antichrist claiming to be jesus. Whatever it turns out to be, I'm sure it will be all about love, peace, happiness, kittens, and puppies, and not about 3-digit numbers, blood, and pentagrams.
Regardless, I'm planning to refuse any sort of implantable identification technology (or any oath for that matter) no matter what. It's just not worth the risk.
