So it looks like they're cloning RFID cards, like access cards for offices (or hotel rooms) but not bank cards with the contactless EMV (ISO/IEC 14443) right?

I think the only RFID thing I have with any access to anything financial is the card I use with the EV charging station. That's got $10 of stored value on it, and it can "recharge" (it's a pun) from a credit card automagically $10 at a time. I guess a crook could sell the charging credit at a discount, like a stolen gift card would be . . .
