0 53731.html In a U.S. government warning high on the creepiness scale, the Defense Department cautioned its American contractors about what it described as a new espionage threat: Canadian coins with tiny radio frequency transmitters hidden inside.
The mysterious coins were found on contractors with security clearances on at least three separate occasions as the contractors traveled through Canada. The report doesn't suggest who might be tracking the contractors or why. It doesn't explain how the Pentagon discovered the coins or how the transmitters function.
