BumpTM makes swapping contact information as simle as bumping two phones together. No typing, no searching a list for the right person, no shaking your phone, no modem noises, no mistakes.

Finally, a business-card replacement that makes sense. Bump provides seamless transfer of information using a shared, secured, authorizable medium. You can’t have my contact information unless I want you to have it. I get to pick what contact information you recieve, and there’s no chance for error at data entry.

Simply brilliant. Another reason I’m still impressed with the iPhone and the developer talent.
