THIS WALLET IS PERFECT, YOU CAN NOT GO WRONG, IF YOU WANT A THIN, COOL/NON SWEATING WALLET THAT SECURES YOU MONEY AND PROTECTS YOU CREDIT CARDS FROM GETTING READ.  WE TESTED IT WITH A WIFI READER AND AS LONG AND THE CARD IS IN THE WALLET, THE RFID READER WOULDN'T PICK UP THE CARD.  WE TOOK THE CARD OUT AND SET IT NEXT TO THE WALLET AND WE COULD GET THE READ TO PICK UP THE CARD INFO FROM 3 FEET AWAY.  THIS IS THE ONLY SO CALLED RFID WALLET THAT ACTUALLY WORKED .  WE TRIED 3 DIFFERENT WALLETS.  THIS ONE WORKED.
