  Hello,
  As far as I understand, you were asking whether you can change the available Keywords dictionary so your app can perform custom field extraction similar to BCR functionality. If so, then, unfortunately, this is not possible. You can only use available fields, or perform full-text OCR of the image, then search certain keywords and try to identify the corresponding field value near each keyword that you found (e.g. using keyword coordinates on the image).
  
  Regards
  Tim

  Thanks,
  
  Where can I find technical documents for it? If you mention "available fields", where can get those?
  How to get keywords/ field value based on co-ordinates of char?

  Hello
  
  You can find documentation in the distributive folder by the path "MobileOCR.Android\Help\MobileOCR_guide.htm" (or "MobileOCR.iOS\HelpMobileOCR_guide.htm").
  
  The information about the fields which can be extracted from the business card can be found in the article Guided Tour -> Recognizing Business Cards.
  
  If you would like to perform fields extraction based on your custom logic, please try the following approach:
  1). Perfrom full-text recognition (using the function FineRecognizeImage()).
  2). Walk through the text blocks (they can be accessed via CFineLayout::TextBlocks) and text lines (CFineTextBlock::Lines). Both CFineTextLine and CFineTextBlock provide the coordinates info. The recognition text can be obtained via CFineTextLine::Chars.
  3). Basing on the obtained info you can find custom keywords with corresponding coordinates.
