Credit and Debit Card Details Hacked While Still in Your Wallet

The cards at risk are enabled with radio technology that allows you to "PayPass" There are remote tools that thieves can use to steal information from those cards. A security specialist at Chicago's Trustwave, used a device in his backpack to read account numbers and expiration dates - all from cards which were safely tucked away in a wallet. Spokespeople representing MasterCard say that the 3-digit code (CVB) on the back of the card is usually needed for purchases, and that code can't be read by the device. To fight back, you can buy special wallets and even cheap sleeves that block the radio frequency. You can also use al-foil.
