First of all... great idea! To think that you could simply hand someone your business card and effectively transmit your companies message is brilliant. Personally, I think something like this should sell it self. But is it possible you can give me some additional info on its features, capabilities, size, weight, and cost per unit? That would give me a great foundation with which to work with. If these are pretty close to the dimensions of business cards and they won`t be too expensive. You have a hit on your hands.
