This is a area I have been researching quite a bit as of late, nfc/rfid implants can easily be used as a means for electronic financial transactions, and some kind of individual marker (think of a individual as having a walking ip address, or a unique assigned number for each individual)
As for recombinant dna, have a read of chapter 4:18 from Book of Yasher, the description and reference to seed mixing.
And as for nanotchnology, this is something out of my league, but there is a question that needs to be asked, is it possible with all this technology, is it possible the brain itself could be hardwired to the point that a person will be unable to change their way of thinking?
And another question, why is it now there are more cases of threats of financial penalties and jail for parents who refuse to vaccinate their children?
I have been wondering as of late if some kind of “mandated vaccination program” could actually be the delivery system used in relation to the mark of the beast (chip implants, nanotch, rDNA, these can easily be delivered via a vaccine).
