This seems like it would be a bit of a faff. With physical business cards, exchanging them is as simple as moving a card from your pocket into the hand of the person you are giving it to. You can even collect a whole bunch at once and arrange them in front of you to remember everybody’s name at the meeting table. Who really struggles to keep track of physical cards? Insert into holder in alphabetical order when you get back. O(n)<p>With this there would be at least a couple buttons to mash on the phone, something will almost certainly go wrong with it in the middle of the Big Sales Meeting (sods law), you have to fiddle with your phone instead of looking your new contact in the eye etc etc.<p>If you are the sort of person that enjoys meticulously tagging mp3 files and has to add every single person they meet to FaceTweetMyspaceLinkedBook then maybe this seems great, but to me this is a solution to a nonexistent problem, that just makes life more difficult.
Some notes regarding your app.<p>Created card, added logo, meant to add it as the picture, no way to remove the logo, won't allow me to upload a picture of the same name? Actually, won't let me upload at all, Chrome/Mac 10.6.6<p>Autofill tries to fill in the street number with the City, and the address line gets my street with the number. I'm not sure why you're separating the two fields. You don't ask for my state. The address appears to be incorrect, as I'm in the USA, our street number comes first, so, I'll assume you're not in the USA?<p>When I try to add my linkedin profile, it says 'Could not add service'. Wasn't obvious that I needed to enter the full url when twitter accepted just my username.<p>As you get further down and click about.me, the dialog box requires me to scroll up for input, then back down. I couldn't see a way to add my self-hosted blog.<p>After saving the card on step 2, I am able to upload my photo and deactivate the logo.<p>I'll give it a try this weekend, however, on android, it is based on email which means I have to hope that the email gets delivered. Does the IPhone app transfer it locally? or still go through your server?<p>It looks good, pretty easy to navigate. I hope it works out well for you.
Saying that an area the 120% size of Central Park is deforested yearly to create business cards doesn't at all follow from what they claim. There may well be 24,000 trees in NYC's Central Park, but the last time I was there it was far from covered in trees. 30,000 could grow in a far smaller space.<p>That kind of reasoning doesn't inspire confidence!
I could see something with NFC being much more productive than this. Actually have a plastic card, and just scan that sucker to each other's phones. This is an interesting idea but still doesn't really get rid of the paper usage because people like to have something physical.
