RFID Access Card Hacks

I spoke with a data security and privacy executive today about a potential attack vector of RFID hacking the access cards. While still not a popular attack vector, or a vulnerability to test in physical access controls, RFID hacks and the tools to do it are gaining ground.

With that said, I can dress in a utility person's uniform and bypass most card access controls anyways...
