Are You Ready For Your Microchip?

You might not realize it, but the science behind the VeriChip is already big business. VeriChip uses radio frequency identification, or RFID technology. Last year, vendors shipped 500 million RFID chips to the U.S. military and companies like Wal -Mart for use in inventory tracking. Your pet may be one of the more than 6 million animals chipped since 1991. Highway toll systems use it to automatically charge you. And the latest U.S. passports sport RFID chips. RFID tracking has become a part of our everyday world. And that may pave the way for more implants, even mandatory ones.
