Does not block RFID scanners
Does not block RFID scanners. I literally scan my badge into work every day through it. Other than that, they are nice wallets, but only last about 3 years before the leather starts crumbling off. This is the second one I have bought. 2 Stars because they only last about 3 years and does not block RFID scanning as advertised.

Nice Wallet
Size: One Size, Color: Black
This is a pretty nice wallet, although calling it 'minimalist' might be a stretch. With the availability of Apple Pay and others, and the decline of cash, there is no longer a need to carry all your credit cards and money in your pocket. There is also a trend to allow you to put a legal image of your Drivers License on your phone. So as a result, wallets are getting smaller and thinner. This wallet attempts to achieve that, but actually I could do without the cash pocket and also the completely unnecessary fold out flap for your drivers license. I thought this flap could just be slipped out of the wallet, but it's actually sewn into the top of the card seam. When I received the wallet, I carefully cut off the flap above the seam, along with a ridiculous number of sewn-in tags in multiple languages, and this worked out pretty well. I can carry this wallet in my front pocket fairly easily. So for the price, I am pretty satisfied. Prior to this I was using a card case with 4 slots which I may go back to at some point. I'd have to say that unlike this wallet, the card case is truly minimalist.
