I really like this wallet. The metal frame keeps my car secure and I can sit without bending them or worrying about them breaking. There's my driver's license in the little hatch and I'm glad they didn't fool him by trying to put a plastic window in there. Because of the metal frame and the way it closes, you don't need it. It's supposed to be rdif protected but I'm not sure as my temporary card is also in my wallet and I don't have to take it out to insert it. I just wave my hand in front of the scanner and it works great. Might be a different type of system, great wallet anyway thanks guys five stars!
