The VeriChip, which transmits a unique I.D. number by radio frequency to a scanner, actually has been implanted in more than 30 people for a variety of potential applications, including as a building I.D. "badge," medical "bracelet" and anti-kidnapping device. Now the chip's creator, Applied Digital Solutions Inc. (ADSX) of Palm Beach, Fla., is pitching it as a digital wallet that could automatically make purchases in stores. The device employs radio frequency identification technology, or RFID, which companies such as Wal-Mart Stores are testing for more mundane purposes such as tracking inventory and ringing up products at the register. For example, a chip embedded in a product or its packaging can transmit signals informing the retailer that it has been removed from a shelf or purchased and needs replacing. But how does one install such a chip in a human? Easy, says Applied Digital: "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." So will muggers start carrying around scalpels to steal your wallet?
