Credit Card Belt Buckle.

Ever want a really handy place to store your credit cards? How about your belt buckle? No? I thought it was a bad idea too but a Swedish company seems to think there's a demand:

Now I can't imagine thieves would think to mug you for your belt, especially since the buckle would have to be larger and thicker than your standard credit card. And there is a certain James Bond appeal to the whole thing. But seriously... if I started pulling Amexes out of my trousers to pay for things that would raise more than a few eyebrows.

Unless you're in Sweden-- they're very permissive.
