If you’re concerned about your RFID-chipped credit cards being skimmed, you might want to consider shielding them. DIFRwear makes a wallet with the shielding already included, and now roguewallet in Maine has introduced its own RFID-shielded version, with a fin-shaped design so it fits better in your front pocket to thwart pickpockets. Unfortunately, it’s also $50, compared to $20 for the more conventional looking DIFRwear hip-pocket design. (Both are FIPS 201 compliant, if that means anything to you.)
Or, if you want to go the really cash-conscious route, make your own.
