RFID Blocking (wireless theft) 

Radio Frequency Identification is becoming an increasingly  common feature on credit cards that allows the user to wirelessly "swipe" their card. However, the technology is inherently vulnerable as it lends itself to wireless identity theft. A portable, concealed scanner is all that is needed to wirelessly obtain credit card information from RFID-enabled cards in your wallet, a process known as "skimming". The Ridge’s aluminum plates block RFID when fully inserted, keeping your information safe. A quick push of your finger exposes the cards, allowing you to utilize the convenience of RFID enabled cards without risk.
