There are plenty of ways to exchange contact information, but they generally require that people have the same app on the same type of smartphone, as well as requiring both parties to agree to share information. 203-403-NAME make this process extremely simple, by only requiring an online handle (username).

Meet a cool entrepreneur, investor, or tech person? Just ask for their twitter handle, text it to 203-403-NAME (203-403-6263), and instantly get a vcard for them that you can easily import into your phone or computer address book. It pulls a surprising amount of public and semi-public information from a variety of social and other sources. Some information that can be included: full name, company and title, email (occasionally), phone number (occasionally), home page url, home location (generally city-level), description, summary, Klout, photo, facebook profile link, and other social profile pages.

It’s easy! Just text an online handle/username from twitter or other service to 203-403-NAME (203-403-6263), and get back information instantly. You then just reply with your email address and it will send you a vcard file, ready to import into any phone or address book in just one click. The email method is required because of limitations in smartphone operating systems (the only way to import a vcard is via email). But don’t worry, the service remembers your email so future lookups are even faster.
