Cool Looking Business Card with LCD Screen

Paper business cards are boring, everybody has one.  You need something that gets attention when you hand out your business card.  Today’s idea is to make a business card with a small LCD screen displaying your information continuously.  It also operates on solar power just like a calculator.  Maybe it could have a calculator built into the back so people would keep your business card in use all of the time as a calculator.  So the next time your potential client was adding up a few numbers she would think of you, her favorite vacuum salesman.
