I'm researching an article about the amazing range of ways apps use your iOS camera, from barcode readers and business card scanners to augmented reality and color detection for those who are color blind. This new app released today is yet another great freebie. Shoeboxed Business Card Reader lets you use your camera to take a photo of the card. The info is uploaded to the Shoeboxed.com website, which uses optical character recognition to extract the data and then add to your contacts automatically over-the-air. The service actually uses people to verify the accuracy of the scan of each business card before adding to your contacts.
