Seen it. It's going nowhere fast. The fact is that although it purports to simplify things, it actually makes more complicated. Most people need to carry a wallet anyway for cash and ID purposes, so adding a couple different cards into the mix doesn't especially complicate things. If you're carrying your cards anyway, it's a simple matter to pull out the right one.
