The FOX News reporter that introduces the segment can be heard saying that the chip "will kill you if you get out of line" (http://www.youtube.com/watch?v=yl2L...).
Later in the YouTube compilation around 04:45, Chairman and CEO of Applied Digital Solutions Scott Silverman, who happens to have a "VeriChip" in his own arm, promotes the technology as useful and beneficial during a CNBC segment. Several of the hosts can be heard questioning Silverman about the "slippery slope" of the technology, and how it could be used to control the world's populations.
The PositiveID Corporation, which produces the VeriChip, has also announced that the Israeli Military recently ordered implantable microchips for its soldiers. The stated reason for this is that the chips will supposedly aid in "disaster preparedness and emergency management" (http://www.rfidnews.org/2011/10/11/...).
Assuming that they will only be used for the benign-sounding purposes that their proponents claim (which is highly unlikely), human microchips are a privacy nightmare that is much worse than credit cards and cash. Because human microchips transmit information via RFID and GPS signals, criminals can easily hijack personal information by intercepting transmission signals.
