5 Stylish RFID-Blocking Wallets

Paranoid Privacy geeks have never been comfortable with those tap-to-pay credit cards and certain office-access cards that many of us have to carry, because they have tiny antennas that can convey data (usually encrypted) over low-power radio waves. One way to jam that transmission? Using a radio-frequency-blocking wallet, which are commonly lined with a special foil. Although they were once strictly available in stodgy neutrals, these niche wallets have fashionably evolved to satisfy everyone on the sartorial spectrum, whether you’re looking for something subtle, such as Tumi’s in navy nylon, or statement, as in relative newcomer Kena Kai’s in croc-printed leather.
