This card wallet is exactly what I was looking for: it's thin, it has a window for my permit and holds my cards. I'd found others that would work and were cheaper but I decided that if the Rfid worked it would be worth the extra cost. Once I put all of my cards in it and placed it my back pocket, you couldn't really tell that it was there, which is what I was hoping for! There are 2 reasons why this card wallet is great for me: 1. I'm a tomboy and don't like to carry a purse everywhere I go and 2. When I volunteer there's really not a place to keep a purse for safe keeping, so it's the perfect solution to my delimmas.
