I love where this project could possibly go and I will be keeping my eye close to this one. In my line of business; Licensed Insurance Specialist, you need to optimize every aspect of your brand and your personality. By being able to provide something like this along, people will more than likely share it within their family for two reasons. First, If I do my job as I always do, they will want to send referrals (plus I always reward referrals), and secondly if you have a business card in your hand of that caliber…who are you not going to show how cool it is; right???

My only thought on this type of card, after looking through your picture gallery, is how great it would be to figure out a way to put a logo, call to action or a ridiculous picture of my face over the speaker covering. It just felt like too much negative space sitting there in the open. I don’t know what material you are using or thinking of using, so I don’t know if something like that would work…but I would definitely buy as many as I could depending on price point. You have a really cool thing going here. I can speak to my future client before we ever meet!
