LunarFox writes "Applied Digital Solutions has announced successful field trials of a prototype GPS device that can be implanted into humans. The device, which is internally rechargable, can wirelessly transmit location, movements and vital signs via the Internet, storing the info in a database. It's said to be the size of a pacemaker, but they intend to miniaturize it to one-tenth that size. You may recall this company as having designed the 'Digital Angel,' and 'Verichip,' a ricegrain-sized RFID chip like injectable pet tracking ID chips. This same company apparently made several denials in 2002 that their product(s) would be anything but externally worn. (like a wristwatch) Many other related links can be found at WorldNetDaily." On one hand the potential cool uses astound me, while the possibilty of abuse frightens me. A lot.
