Is the VeriChip secure?
The data on a VeriChip implant is not secure. Because a VeriChip ID number is transmitted through the air via radio waves, it can be easily picked up by anyone who holds a reader device within a few inches of the chipped individual. From there it is a simple matter to clone the signal. Two separate security researchers, Jonathan Westhues (in 2006) and Adam Laurie (in 2007), have demonstrated this ability in public.
