Yup. The new RFI chips that are put into credit cards these days are like a gold mine for identity thieves. I've read that in some cases the signals from these chips can be read from almost 40 feet away!
It used to be you had to walk right next to the person to read the info on their card, now it can be read by driving down a street next to a line of people. I've started to look into faraday cage type wallets that block all those signals...
We have had our credit card numbers compromised many times in my family. We finally figured out it was because of our mandatory full serve gas stations. You aren't allowed to pump your own gas here (municipal by-law to ensure jobs for young people...). Basically you sit in your car, they pump your gas, and you hand them your credit card to pay, and as they head inside they quickly copy down all your info.
Lets just say we go the extra 2 minutes to the adjacent city to pump our own gas... or use cash/debit.
Even your debit isn't always 100% safe though. We have had instances of people swapping their own debit machines for the store ones, which work like a regular machine except record all your banking/card info as well. Then after a few days they go back in and swap it out, walking out with hundreds of numbers for bank accounts and credit cards.
Scary stuff. It doesn't seem to matter how hard we make it for criminals, they always find a way to beat the system.
