Credit card companies successfully nixed a Mythbusters segment exposing RFID’s security flaws, according to Arbiter of Truth and Mythbusters co-host, Adam Savage.

“Texas Instruments comes on along with chief legal counsel for American Express, Visa, Discover, and everybody else… They were way, way outgunned and they absolutely made it really clear to Discovery that they were not going to air this episode talking about how hackable this stuff was, and Discovery backed way down being a large corporation that depends upon the revenue of the advertisers. Now it’s on Discovery’s radar and they won’t let us go near it.”
