VeriChip
VeriChip (now re-branding PositiveID) was the only Food and Drug Administration (FDA)-approved human-implantable microchip. It was marketed by PositiveID, a subsidiary of Applied Digital Solutions, and it received United States FDA approval in 2004. Its manufacture and marketing were discontinued in 2010. About twice the length of a dime, the device is typically implanted between the shoulder and elbow area of an individual’s right arm. Once scanned at the proper frequency, the VeriChip responds with a unique 16 digit number which could be then linked with information about the user held on a database for identity verification, medical records access and other uses. The insertion procedure is performed under local anesthetic in a physician's office. As an implanted device used for identification by a third party, it had generated controversy and debate. VeriChip's merger in 2010 officially changed their name to "PositiveID."
