I've used this wallet exclusively for over a year now, there are no frayed edges or damaged sides. Like other reviewers, I tried my proximity badge in it and it was unreadable. It should be impossible to do a walk-by read of any of your card strips in a crowd. I'm very pleased with the quality of the build, it looks good, and holds a lot of cards and papers.

The only downside is predictable. When you travel, or enter a courthouse, when you go through a metal detector you have to take it out of your pocket and put it in the tray because the inner foil detects as metal. This does present a risk of loss, and you need to keep your eye on it. Keep this in mind, and you will be very satisfied with this wallet.
