B.E.A.S.T. stands for Biological Encoding and Satellite Tracking. This doesn't replace the European Union beast or the 1st beast (Antichrist) or 2nd beast (False Prophet), but these beasts utilize the the mark of the beast.

If you take the mark of the beast implant under your skin to buy and sell it is already too late for you. You're toast! You will never repent.
