The new about.me app is hoping to replace the traditional business card. Called Intro, the app functions on the observation by Founder Tony Conrad that you might not have your card on you, but you definitely have your phone. In an attempt to be the "digital business card for mobile," Intro uses the information typically found on your about.me page and puts in into a mobile format.
In addition to having your about.me profile easily accessible, the app also allows you to share your contact information with others. Whether you choose to share "the whole shebang" as TechCrunch puts it, or simply your email, you can use the about.me app in a way that suits you best. Users can also track the people they've shared info with, as well as the cards they received.
