I have developed iphone app with OCR scanning feature. Using Tesseract api, got the text from the image taken. But now i need to separate each text with respect to name, address, email, phone number etc. Because business card structure/format is not specific, its bit of difficult to assume.
However few things assume 1) "@" containing string mostly going to be email id. 2) all digits with braces or + sign mostly going to be phone number.. but still there are lots and lots of possibilities.
