From CNET :

"Radio tags used in everything from building access cards to highway toll cards to passports are surprisingly easy to copy and pose a grave security risk, researchers said this week.

At a pair of security conferences here, researchers demonstrated that passports equipped with radio frequency identification (RFID) tags can be cloned with a laptop equipped with a $200 RFID reader and a similarly inexpensive smart card writer. In addition, they suggested that RFID tags embedded in travel documents could identify U.S. passports from a distance, possibly letting terrorists use them as a trigger for explosives."

The story goes on to note that similar vulnerabilities exist with RFID-based credit-card technologies.

Does this scare anybody besides me?
