They don't care, they already have people with the mark, the very fact that people think its a chip, is bad enough . So they are not worried. They love that Christians cant read Revelation with any degree of understanding. Plainly the mark is your lack of God's words in your mind. They are walking dead, ignorant of God's word and don't care or know. People have the mark just about; the next step is to worship the fake as the messiah when he is booted to seal the deal. ( rev 12: 9 )
