Ahem: you can't falsify banknotes with regular printers and commodity paper well enough to fool an alert human being, but the scanners in some vending machines

Ahem: you can't falsify banknotes with regular printers and commodity paper well enough to fool an alert human being, but the scanners in some vending machines are another matter. With 7 colour 1200+ dpi inkjets readily available for photo printing, if you could find a vaguely passable source of paper you could do wonders -- and one option forgers have used is to take low value notes and bleach them before overprinting with a higher denomination print pattern. (I think this is the rationale for high-denomination Euro banknotes -- €50 and above -- having embedded RFID chips.)

Citation needed You can't take a lower denomination bank-note and print a higher denomination one on an Euro note: the sizes are different (of course, maybe you can pass one note for the next in sequence, but it is slightly harder) Also no RFID is mentioned here https://en.wikipedia.org/wiki/Euro_banknotes#Security_features https://en.wikipedia.org/wiki/Euro_banknotes#Security_featur...

- JoeAltmaier 11y agoHm. I guess officially. Yet they were FBI. Here's another case: https://www.fbi.gov/minneapolis/press-releases/2010/mp052010a.htm https://www.fbi.gov/minneapolis/press-releases/2010/mp052010... and it says "This case was the result of an investigation by the U.S. Secret Service, the Minneapolis Police Department, and the Federal Bureau of Investigation."
