Not commonly known, but all modern (last 10 years or so) colour printers secretly put tiny UV-visible dots on every colour page they print - the dot pattern contains the serial number of the printer, the date and other information. Lots on the www about this... i.e. if you use a colour printer to print money, you'll shortly be in jail...
More recent, top-end, copiers will automatically detect that you are trying to copy currency, and refuse to even attempt it.
Damn...nowt's simple these days
How about some Tin Wiskers?
