Feds at DefCon Alarmed After RFID’s Scanned Threat Level Wired.com
The very proponents of RFID chip usage have had the tables turned on them, as one might expect, in Las Vegas.
At the DefCon hacker convention taking place now, attendees set up an RFID scanner which photographed chip carriers. These of course included various feds - under cover and not - in attendance.
The amiable scanner owners were kind enough to destroy the data in public view, after letting the "Meet the Fed" panel drop jaws when they heard the news. Lucky for the feds it was such a friendly environment. Is everyone else who scans for RFID's so friendly?
