[Hodar]

9A third angel followed them and said in a loud voice: "If anyone worships the beast and his image and receives his mark on the forehead or on the hand, 10he, too, will drink of the wine of God's fury, which has been poured full strength into the cup of his wrath. He will be tormented with burning sulfur in the presence of the holy angels and of the Lamb. 11And the smoke of their torment rises for ever and ever. There is no rest day or night for those who worship the beast and his image, or for anyone who receives the mark of his name."

Revelation 14:9-11

Biometrics is no more the mark of the beast than fingerprinting. There is no mark made on your hand, head, foot or behind. It justs records measurements of your hand (joint positions, finger lengths, fingerprints, ect) on your Drivers License; making it harder for someone to steal your identity.

I'm not worried that I'm carrying the mark around in my pocket on my driver's license.

But I'm also not the least bit in doubt that it's the first stages of the slippery slope.
