Credit card style Bluetooth device isn't likely to increase your wealth, coolness
We've seen some ultra-thin MP3 players, even ones that were credit-card sized, but this newest one actually masquerades as a credit card, numbers and all! There's perilously little information available about the device, but we can tell you this: you'll look and feel awesome sporting it, should you ever be able to get your hands on one; which we doubt. Price and availability are a mystery to us all.
Update: As pointed out by several of our astute commenters, this appears to be a Tokyo Flash concept for a Bluetooth adapter modeled on a previous credit card styled MP3 player.
