==Background==

Counterfeit banknote detection pens are used to detect [[counterfeit]] [[Swiss franc]], [[euro]] and [[Federal Reserve note|United States banknotes]] amongst others. Typically, genuine banknotes are printed on paper based on cotton fibers, and do not contain the starches that are reactive with iodine. When the pen is used to mark genuine bills, the mark is yellowish or colourless. Counterfeit pens are most effective against notes printed on standard printer or [[photocopier]] paper.<ref>{{cite web|url= http://money.howstuffworks.com/question212.htm |title=How does a counterfeit detector pen work? 123 | work=HowStuffWorks ||accessdate= 2008-03-28}}</ref>
