Bob,
If you're looking at U.S. money, they are slowly changing (or have already done
so by now) the overall look. The U.S. engravers have made the portraits larger
in size, added some minute laser inscriptions, and are now introducing a wide
color band through some portion of the paper to further foil counterfeiters,
and many money-changing machines and casino slot machines have had to be
updated as these new bills begin to circulate.
So that would imply that Openbook might be impacted by this migration into
colors, and if you have an older version of Openbook (7 or earlier) you might
indeed have some issues with Buckscan.
Buckscan consists of a set of images stored in memory, of key portions of
various paper-money denominations that are used to do a comparison with the
image you scan in. The better the correlation, the more likely it is that
Buckscan will recognize the money.
If the bill is worn, wrinkled, folded, or otherwise marked in those key areas,
recognition will be negatively impacted. Same holds for any changes made by the
engravers to foil counterfeiting.
The key areas are the corners of the U.S. bills, as this is where the
denomination ($1, $5, $10, etc.) is engraved, front and back. So the images
stored in Buckscan are not images of the entire front and rear, just the
corners.
So long story short, if you don't have the latest Openbook, that could be one
problem. If you do, it could also be due to the quality or revision of the bill
you're scanning.
You might want to check with Freedom Scientific to see if they have any updates
to Buckscan.
Dave

I know OPEN BOOK isn't perfect, but does anyone have any suggestions
regarding the buck scan feature. Most of the time it won't even read the bill
in question, and its incorrect so often, I don't trust it. help, Bob
