iOS/Android: You go to a conference, you get about 40 business cards, and, well, maybe you remember to go through each and every one and add their details to your contacts. Or you fire up CamCard, snap a picture, and have its text quickly transcribed and entered into your contacts.
CamCard offers its own camera function to snap an image of a business card, preferably head-on in a decently-lit area. It rotates, flattens, and enhances that snapshot, then runs it through an optical character recognition process to extract the text and numbers on its face. After that, check the entries for name, number, email, and other details against the image close-ups (as seen above), and hit Save, then choose the account you want to save those details to.
CamCard can also read a business card from an image you've already captured, and it saves your card images to your storage. From the cards it's saved, CamCard also allows for quick look-up and calling, emailing, or LinkedIn browsing right from the app. If you have a host of cards to move through, or you just got a card that's a bit more important than the rest, CamCard looks like it could be really handy. I'll be using it to punch through a host of cards from South by Southwest.
CamCard is offered as a free "Lite" download, limited to saving 10 cards your first week, then 2 cards per week after that. Upgraded versions for iOS and Android offer unlimited cards and additional languages (in Western/European and Asian packages).
