My chipped credit card (less than two months old) that I carry in a signal blocker wallet was hacked faster than any other credit card I've owned. I just got a call from my CC company yesterday to ask about $2500 worth of charges that were not mine. Jeez...

And your info is still vulnerable that way. Plus, many/most stores don't have chip readers yet.

I had to laugh. WM in Canada recently upgraded their CC machines. They don't do chipped cards the way every other store/kiosk in Canada (and the rest of the developed world) has for years. So basically they're at 2000 now, their previous machine were 90s-style clunky. I do understand the infrastructure required in the U.S. would be massively more expensive than anywhere else.These cards also have a unique transaction code that only the card and the "data receiver" know about, so they're much harder to hack than unchipped cards. However you can make *small* purchases with them only up to a certain *total* amount ($100, $200 is common), then you have to enter a PIN to "reset" the amount. You can't buy $2500 of stuff just by waving them. Banks aren't that dumb.

If you can only charge $100 or so without resetting the PIN, how did Rockethead end up with $2500 worth of unauthorized purchases?
You're right, I made a mistake: it's only for a *debit* RFID card that you reset the running total by entering your PIN.
For a RFID credit card you have to enter a PIN if it's over a set amount, but if your purchases are under this amount (usually it's $100 here), you can keep waving away until you hit the credit limit or are otherwise stopped.
My bank just issued RFID credit and debit cards. Guess I'll have to learn the ins and outs of using them. So far nowhere I've gone in my home town has had the RFID scanner.
