separately. This way, you can reduce the processing time
considerably.
To recognize batches of cards:

Sort all the cards you want to process by country and scan them.
Sorting cards by country is essential as you can only select one card
style at a time.

Then click Batch OCR on the Process menu.
Note that the command Batch OCR is disabled when you are viewing
a card in card view. If necessary, click the album view button to
return to album view.

Batch OCR takes the card status of cards into account while
executing the recognition:
o Cards that have the status New will be recognized. Any
data that had already been filled in will be erased and filled
in again.
o For indexed cards, the system will try and fill out all
empty data fields - all fields which already contain data are
considered validated by the user.
o Batch OCR will not be executed on verified cards.
For more information about card statuses, see the section Assigning a
card status.
You can also batch OCR a selection of cards:

Ctrl-click a selection of cards in album view and click the Batch
OCR command on the Process menu.
