Declan McCullagh has a nice review of efforts around the country to regulate RFID. Like most places where technology and public policy meet, there's plenty of chances for politicos to act in uninformed haste. Utah had an bill sponsored by David Hogue that was thankfully defeated. This is a perfect example of solving problems that don't exist. There are some legitimate privacy concerns, but no one's actually using these devices at retail yet, let alone using them in a way that requires regulation.
