The first time you launch the app, you'll be asked to "fill out your card" by typing your name, phone number, and e-mail address. Attach a photo, if you wish, to this virtual card.
Now, you can transfer that information and get the same in return at a "light fist bump," as instructed, with anyone else running the Bump app.
You can also pass along information from others in your phone's contact list, or with photos stored on your phone.
The app has a novel way, too, of bumping photos to a laptop or desktop computer. With a bump of the phone against your space bar, the app sends pictures to a website, http://bu.mp, from which you can drag and drop them to any PC folder. The caveat here is that the process works over the Firefox, Chrome and Safari browsers, but not via Internet Explorer.
When you can't escape the material world, ScanBizCards Lite, free from ScanBiz Mobile Solutions L.P., lets you take photos of old-fashioned cardboard business cards and send the information on them into your address book.
The app, for Android and Apple devices, detects a slew of printed languages, including in the Greek and Russian alphabets.
The Lite version of ScanBizCards allows you to save only five cards a week to your address book, but unlimited card-scanning is possible. A "premium" edition of the app, which allows unlimited card-saving, costs $6.99.
A free app called ooVoo Video Chat can, among other things, make an iPod Touch work like a video telephone among users of the app. It also works on other Apple and Android mobile devices.
For networking, the software, by ooVoo L.L.C., can conference up to 12 video callers, although 12 Chiclet-size faces, all with squinting eyes, on a smartphone screen could be a bit tedious to watch. (With Skype and a similar video-chat plug in for Google+Hangouts, you can conference up to 10 users).
For desktop use, ooVoo has PC and Mac versions.
