You can also try covering half the note with a piece of paper and scan that. Then cover the other half of the note and scan. Then use an graphic editor to combine them.
Yeah I already tried that and it detects even a very small part of the bill, even if it's only about 20% of the actual bill showing. This is beyond ridiculous if you ask me...
You can try a different set of drivers; either by downgrading to the oldest available proprietary drivers, or better yet, see if you can find open source drivers.
Once you have the image on your computer, don't use Photoshop to open it. You will be blocked. Instead open it using Image Ready and use the link on the bottom left of the toolbar to edit it in Photoshop.
That will not work. Contemporary printers and some software recognize the Counterfeit Deterrence System (CDS) digital watermark and will not scan or load the image. The watermark is so good that you can cover most of the note and it still will not scan.
That will not help if the scanner itself recognizes the CDS digital watermark. I have a Canon LIDE 200 scanner which recognizes CDS and a Canon LIDE 30 scanner which does not recognize CDS. Using VueScan which does not recognize CDS, I can scan a contemporary note with the LIDE 30, but not the LIDE 200 — The scanner will physically not let the note be scanned.
usually don't have this limitation.
Sometimes I feel invisible....
I see you just fine, Dave!
That's actually not true Bob. The Eurion numbers are for copy machines, but scanners work on a different digital watermark (CDS) that is not visible to the eye.
The EURion Constellation plays a small part, if any at all. It is my understanding that the EURion Constellation is a older (mid-1990's) deterrent primarily for color photocopy machines. It's only needed on one side if you're trying to counterfeit notes on a copy machine.
Neither the front or back of this $50 note can be scanned on a scanner that recognizes CDS, and the EURion Constellation is only on the back of the note.

http://www.cointalk.com/t66215-54/#post1486746 I would like to know what country that scanner was meant for because I have never heard of any legislation in the United States that outright prohibits the scanning or photography of banknotes. Thankfully, my scanner and the factory software that came with it has never given me a problem about scanning banknotes. If it did I would have called customer service or written a blunt letter telling them that there are legitimate purposes for scanning banknotes and to give me clean software immediately. Rant over, lol.
