RFID or Radio-Frequency Identification (RFID) is the use of radio waves to read and capture information stored on a physical tag attached to an object - like the chip on your credit card. A tag can be read from up to several feet away and does not need to be within direct line-of-sight of the reader to be tracked. Criminals use RFID skimmers to steal information using this technology.
All of our wallets are made of premium aerospace aluminum or tightly-woven carbon fiber that hinder and block RFID signals.
