Found in coffee shops all across the country... or garbage.

You hand out your business card. Someone says, "thanks". You leave. They toss in garbage. 

I wanted to postpone that cycle. They say "THANKS", these are cool. They put in wallet. Does that translate into a sale, probably not, BUT you did make it to phase 2. Business cards are slightly overrated and usually end up forgotten and tossed out. Let's face it, if you didn't sell them on your communication skills and talent you're not going to seal the deal with glossy cards with sharp edges.
