Tips:
In case you want to recognize the back sides of cards automatically, select the
option Recognize back side after front side in the Settings menu. This way,
you only need to click the Recognize button once to recognize both sides of
the cards.
Should the necessary information not be extracted from the back side after
recognition, note that you can still use drag-and-drop OCR and OCR on
the fly on the back side of cards to add additional information to the database
fields.
When you always want to scan both the front and back side of cards, make
sure you activate Duplex scanning.
