A few years ago when Discover introduced their mini credit card that was meant to be attached to your key chain and flipped out at the register, I yawned. When American Express recently unveiled their Butterfly card, I was mildly interested. What really has me excited though, is the new card designed by Roger Arquer. It combined a money clip with a credit card so you can carry your cash and plastic in one simple package. A year ago, I moved away from the bulky, carry-it-all wallet, and on to a minimalistic approach (mostly with the help of M-A-K-R). Just a concept at this point, I hope this card makes it into production soon!
