MARK OF THE BEAST & That "Buying & Selling"

And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads: And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name.
Revelation 13:16,17
--Those who have it in their foreheads believe they are doing the right thing.
--Those who have it in their hand don't necessarily believe in it--but they want to buy and sell--be able to eat.
*Mark of the Beast IT IS NOT A CHIP
--side note-- One POSSIBLE WAY to achieve ENFORCMENT
would be through Programmable Digital Currency.
(Remember--that WOULD NOT BE the MARK OF THE BEAST but rather a way to enforce the Buying and selling aspect).
