Looking for a card reader for your iPad, check out CamCard HD by IntSig. You can import your business cards through the camera and run OCR to detect the name, email, website and more. You can keep the business card picture on the iPad, take a picture of the back or remove it altogether.
You can save your contacts to iPhone, Gmail or other accounts. There is even a batch scan option – when you are taking the picture, change the slider to multiple business cards. Then just snap a card then move to the next.
When you are done, check the cards for spelling and other OCR mistakes. When all is good, check it off and share it to your lists. You can even send email right away.
Best part – CamCard has a QR code option – pull up a card and choose the QR code. Then others can scan the card and get the information on their phone.
CamCard is $6.99 (they have a special going right now for $2.99).
