Mexican Attorney General Gets Microchip in Arm
novakreo writes "Rafael Macedo de la Concha, Mexico's Attorney-General, now has a non-removable microchip in his arm, to track his movements and to give him access to a new crime database, according to Bloomberg. The article says that eventually around 160 Mexican officials will have a chip implanted." (Wired and CNN are both running the very similar Reuters report, too.)
The technology exists such that they could in theory make this thing only operate when pysically attached to the body ( say, powered off of blood or bloodflow ), and only operate when in contact with his specific blood type.
So to use it, a perpetraitor would have to a) Kidnap him, b ) cut off his arm, c) surgically graft the thing into someone else with the same blood type.
Hopefully by that point they'd have de-activated his chip.
I imagine in a few years we'd even be able to make these things DNA specific.
