Randall Parker spots this announcement.

The standard location of the microchip is in the triceps area between the elbow and the shoulder of the right arm. The brief outpatient “chipping” procedure lasts just a few minutes and involves only local anesthetic followed by quick, painless insertion of the VeriChip. Once inserted just under the skin, the VeriChip is inconspicuous to the naked eye. A small amount of radio frequency energy passes from the scanner energizing the dormant VeriChip, which then emits a radio frequency signal transmitting the verification number.

My guess is that some people have already been chipped (not necessarily using this company's product) and that they were not volunteers. Think about that the next time you read about someone in the Middle East being arrested as a terror suspect and then released.
