RFID stands for Radio-Frequency Identification. If you have a chip inset in your card, you are at risk of skimmers getting your info when you're shopping or traveling without you ever knowing it. 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 purple zebra stripe embossed leather, hand stitched with multicolored thread, and inside contains RFID shielding. Single pocket holds 2-3 cards depending on thickness.
