RFID blocking protects your credit card from unauthorized digital scanning, known as RFID skimming. While convenient, RFID-enabled cards can be read by thieves using hidden scanners within a few centimeters—especially in crowded places like airports or trains—without you noticing. These scanners can capture your card number and expiration date, potentially leading to fraudulent charges or identity theft.

These are nice-quality blockers that are great for men's and women's wallets!  This awesome card is the size of a credit card but a little thicker. Add it to your wallet to prevent scanning!  If you have a folding wallet, you should purchase 1 for each half.  Note:  You are not buying a wallet; you are buying the insert that goes into your wallet.
