What is RFID? RFID (radio frequency identification) is a growing technology that uses radio waves to read and transfer information between devices.  Personal cards that currently use this technology include credit cards, transit payment cards, and identification cards such as enhanced driver’s licenses.  Why use an RFID wallet? Cards with RFID are vulnerable to scans by a nearby person with RFID readers to capture information without ever physically coming in contact (similar to scanning a barcode). RFID wallets protect cards from unknown scans with the unique protective layering crafted inside the wallet lining.  Feature Security and Privacy Protection: The wallet comes with unique RFID technology, which can block electronic signals to protect your identity when you travel, shop, or explore, and provide excellent protection for your currency cards. The outside notch allows you to push out the cards easily.  Premium and Compact: Made of high-quality genuine leather, the men's wallet is dirt-resistant, abrasion-resistant, and durable.
