So here's a business card that's not as disposable as your average one. The M++CARD combines USB storage with your printed contact info — keep your portfolio, blueprints, schematics, what have you all on your business card — and take it with you so you'll be ready if you're ever ambushed by important people and you don't have anything to show, plus it's easier for them to take with them. A flap on the rear of the M++CARD allows you to fit different sizes of memory to it.
The same end result could probably be achieved simply by taping a card and a thumb drive together, but who would take you seriously? The M++CARD is just a concept at this time.
