Actually, the forehead/hand reference from the Torah is sometimes literal and sometimes figurative. If the commandments are only bound in one's tefillin (phylacteries), then one hasn't followed Torah at all. So, most of the mark of the beast is in whose commands one obeys, not in the technology which one wears or implants.
So, with laws like this, a substantial portion of the camel is under the tent!
um....HUH?
