So, you're in art, craft, or trade show. You meet someone and he asks for your business card. You say 'Wait, let me get one'. At this point, you're a little bit panicky. Your precious cards got somehow lost amongst the pile of mounting flyers and items you've accumulated.
The answer to your dilemma, the Card Cache. I came up with another fun design with two things in mind - simple and convenient.
No more card-hunting, just caching in.
