That is a function of the software, not thescanner. I use Cardscan
(Corex), it both saves the image and OCRs the contents. There is really
no reason not to OCR the contents (the OCR is very good, and very fast
-- just 2 or 3 seconds, literally). You really do need to OCR if only
to be able to do searches to find thecard(may not sound like a big
deal, but mycarddatabase has thousands of cards).
By the way, with Cardscan, you can use any flatbed twainscanner, and
more to the point, you can lay 8 cards on thescannerand scan them all
at once (one note, you need a black, not a white background). Cardscan
will delineate them into separate cards and save them as if they had
been scanned individually.
