I think that I may have brought this up already.Isn't the mark of the beast more about worship than chip technology?
Revelation 13:4 And they worshipped the dragon which gave power unto the beast: and they worshipped the beast, saying, Who is like unto the beast? who is able to make war with him?8 And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the world.
12 And he exerciseth all the power of the first beast before him, and causeth the earth and them which dwell therein to worship the first beast, whose deadly wound was healed.
However, it is to him to make war with the saints, who are those that do not worship him:
Revelation 13:7 And it was given unto him to make war with the saints, and to overcome them: and power was given him over all kindreds, and tongues, and nations.
So, I think that it may be possible that the second beast uses the mark, or the number, to "smoke out" those not worshipping the beast.
Revelation 13:17 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.
It doesn't look like he needs to that to "force" people to worship the first beast, as they will already be doing that.It looks more like he needs to do that to try and expose those who are not worshipping the beast.
