rmbr, gives me that option.
Their app, called beamMe, is an extension of the rmbrME app the company launched back in August. While that application was meant for use with all phones using text messaging, the iPhone app is a bit more slick and even easier.
When you start up beamME, you tell it which contact information in your address book to import as your own (or you can enter your own if you don't have an address book entry for yourself). Once that's done you have two options: 1) Beam your contact information to a mobile number (in the U.S.) using a text message or 2) Beam your contact information to an email address. You can add some optional notes and your name if you like. In a world of ever-increasing features and buttons in applications, this simplicity is nice.
While the text message option requires the recipient to visit rmbrME's website to get an email sent to any address (preferably one set up on your phone) so it can send you the vCard data to download, sending your information via email directly from the beamME app cuts out this middle step.
But it's not quite as simple as the recently launched application Handshake, which uses company servers to provide over-the-air instantaneous syncing. Still, that app has two big limitations: 1) It requires that both users have the Handshake application, and more importantly, 2) It requires that both users have iPhones. BeamMe will send your information from your iPhone to any device.
Also, assuming you pass the first two limitations, Handshake also requires that you swap the data when you are in actual close contact with the other person. For times that you may not have your phone on you or simply don't want to pull it out to do a swap on the spot, beamME offers a compelling alternative with its email option.
BeamMe is a free app, available here in the App Store.
