CardMunch For iOS
If manual data entry is out of the question and only free apps will do, then CardMunch might still fit the bill. Acquired by LinkedIn last year at this time, CardMunch for iOS is a free app that photographs and sends business-card images to a free service that manually transcribes them. In theory, the service promises a 10-minute turnaround, after which a push notification is sent to the phone telling the user that the text is ready to be approved. Users can then edit and save the contact to their phone, LinkedIn or both, or they can delete the contact entirely.
