The big question: does this wallet really block RFID readers? I have no way of testing it. It sucks. However, the wallet is a winner for me. Design, structure and appearance are very good. I have too many cards for most wallets. (Maybe a chip with all the data is a good idea?) Anyway, it does a great job of storing my 17 magstripe cards, a few business cards, and paper money. Yes, it's a bit bulky with cards and a bit wider than most wallets, but it's usually in a cargo pocket, jean pocket, or blazer pocket and it works. If the wallet lasts a few years, the cost is worth it.
