RFID wallets that don’t skimp on style

The acronym RFID refers to radio-frequency identification, the use of electromagnetic fields to automatically identify and track digital data. Think of an RFID tag as an intelligent bar code that doesn’t announce itself with a large block of black lines. It makes using credit cards easier but could also, potentially, leave your data exposed even when your cards are stashed in your wallet. The idea that RFID data could be vulnerable at all times has given rise to an array of “RFID-blocking” devices and, yes, even wallets. And they combine style and security—for men or women—while still giving you digital peace of mind.
