InternetVoting writes "California has passed a bill banning companies from requiring employees to have RFID chips surgically implanted. Already one company has been licensed by the federal government, implanting more than 2000 people. At least one other company — CityWatcher.com, a Cincinnati video surveillance company — already required RFID implants in some employees. 'State Sen. Joe Simitian (D-Palo Alto) proposed the measure after at least one company began marketing radio frequency identification devices for use in humans. "RFID is a minor miracle, with all sorts of good uses," Simitian said. "But we shouldn't condone forced 'tagging' of humans. It's the ultimate invasion of privacy.'"
