In order to have the mark of the beast apply to every person on earth, all 8 billion, you would have to have RFID technology, you would have to have satellite technology, you would have to have 5G technology since it must be powerful enough to spot this in each person, and you have to have this technology they have been testing with the the vaccine where nano particles of graphene attach to your DNA creating a wireless code which can be read.
You would also need a Quantum computer capable of handling hundreds of millions of transactions per minute.
You also need AI to be able to identify issues with anyone and then dispatch the drones, robots and soldiers to deal with it.
Many Bible Expositors thought this only applied to Europe as it seemed impossible to monitor someone on a remote island in Indonesia. But God and Satan would not allow anyone to avoid this judgment.
So even as recently as 10 years ago you could not have had or even considered the idea of "the mark of the beast" being worldwide and affecting everyone, however, the Bible never exaggerates and now we can all consider this will be a reality very soon.
The other thing to remember is that the Mark of the Beast is not implemented until after the Antichrist is revealed and you are clearly in the 70th week, the last seven years of this age.
