Sharon Gaudin at Computerworld writes about a new way to use RFID tags. In this article, a new physical security technique is discussed where a worker who walks into a restricted area would pick up hundreds of tiny RFID sensors on their shoes. As they track their feet across the doormat on the way out, sensors pick up that this employee has entered a restricted area, and then release the hounds.

Cooler than LED Throwies? You be the judge.
