I actually go out of my way to buy wallets without the rfid shielding, largely because I keep my work id in it, and need to use it to get through doors a fair amount, and the readers are generally mounted such that I can get them to read without even taking my wallet out. Honestly, I think the rfid thing is for the truly paranoid myself, and I haven't really seen anything that's convinced me of any true threat coming from people compromising rfid stuff from a distance. That said, if someone wants to do it, whatever, it's not like it's going to hurt anything either.

Quite frankly, the criminals are doing perfectly fine compromising accounts via other methods anyways, so it's probably not even worth the hassle for them to be trying it. (Heck, I have a business account that's had *both* debit card numbers compromised at the same time, and has had it's checking account number compromised, all within the last year. Neither of those would have been anything to do with rfid, so there's still plenty of an attack vector for them without getting too high tech.)
