An absolute favorite with everyone who is using LinkedIn! One touch and you can fire up an invitation to the new contact to join your LinkedIn network – without leaving the app. We even show a little LinkedIn icon on that card to remind you which contact and touching that icon will even show you the status of that invitation … you’ve got to love it. Note: we think you can get a card, scan it, add to the address book, send a quick intro and send a LinkedIn invite in under 90 seconds … if you like to show off, try it while you are still chatting with the new contact then ask him what’s taking him so long to accept your invite.

You can watch this feature "in action" in this YouTube video.
