RFID stands for Radio-Frequency Identification. If you have a chip inset in your card, you are at risk of skimmers getting your info. The best way to avoid this is with a shielded wallet or card case. This case is a one-of-a-kind and was made with a deep purple ostrich embossed leather, hand stitched with multicolored thread, and inside contains RFID shielding. Single pocket holds 2-3 cards depending on thickness.
