Yeah, it was admitted by one and all months ago. See, for example,

(breaking news back in January).

No, it started with the peach $20 in the US. It's also built into foreign
currency, too.

Not sketchy, and the details are know. The software prevents the scanner
from working properly and obtaining a good image. There's a pattern built
into the currencies that the scanning software recognizes and won't copy.
Somebody posted images (scanned with pre-anti-counterfeiting software, I
presume) of several currencies, and the pattern is quite clear. I had a
peach 20 and compared it to the images, and the pattern was quite clearly
there. Don't have one on me at the moment, so I can't direct you to it. On
a 20, it's on the back of the bill and I recall it's lots of little "20"s
printed in a repeating pattern. If you download the back of the 50 from
moneyfactory.com, the little gold 50s are there. The 50s are in a
particular pattern which the scanning software recognizes. Foreign
currencies employ the same pattern in more creative ways. It's the pattern,
not the numbers, that are recognized, and some currencies employ the
pattern as part of an attractive design.
