I have special hat that does this too.

I find the vast majority of RFID paranoia to be misguided at best; it's a technology that promises do theoretically and expensively tomorrow what can be done easily and cheaply today. [Insert rant about government wiretapping here.] The vast majority of passive RFID tags simply broadcast a number that unlocks some larger chunk of data elsewhere. But the idiocy of including name, rank and serial number, as well as identifying biometric data, on the RFID tag itself in the case of the new US Passports for once has me on the side of the tinfoil hat types.... and these wallets are a lot prettier than wrapping your passport in tinfoil.

At first I was pretty hesitant, but I just got a new 'blink' credit card from Chase the other day. I agree with Meghan that some of it is paranoia, but if you need a new wallet anyway, and you have one or two rfid'd cards, why not?

i'm confused. could you like, secretly scan a persons credit card with an RFID reader while passing them by and then go and have an on line shopping day spree or somethinhg?

Great idea, but my security card for work is rfid, and I keep it in my wallet all the time; thanks to not having one of these, I can open the door by just walking right up to the reader... and jrghoull - no. As I understand it the RFID on credit cards just broadcasts the 16-digit number, although challenge-response means it would be slightly difficult to fake. But anyway, even if you managed to spoof it, you still have to type in the PIN to buy anything. ('slightly' - most are not remotely secure really - see http://rfidanalysis.org/)

Sorry to burst your bubble, quen, but "Blink" credit cards from Chase do not require a PIN to complete a transaction.
