Yes it does have to do with counterfitting.
The markers have a special kind of ink that can tell if the currency is real. When they mark it and it turns yellow that means that it is real but if the mark is black that means the money is fake. I am not 100% sure on where you can buy them but I am assuming that office depot or staples would have it. |

Its a special marker so they can tell if the bill is real or conterfit. You can buy the markers at any office supply store. |

Some retail business has those for the cashiers so they can check for counterfit money.
Sorry, I do not know where they get them. You could ask around the different businesses in your area and see if they know. |

Yes. If the mark fails to turn black then the bill is considered fake. I'm not sure where you can purchase one - maybe Office Max, Staples, etc? Sorry! |

Notice that the mark is yellow. If it was fake, it would be a black line. Yes it is for counterfitting. You can steal one from the store you use, but I don't know where to buy one. |

The last thing a counterfeiter wants to do is print counterfeit money on "normal" printer paper. It will feel all wrong, and it can be detected with a counterfeit pen. These special pens, which often look something like a highlighter, contain iodine that changes color when it comes in contact with cellulose. At the very least, you need to try to find thin rag paper to print on. You can find this kind of paper at most office supply stores. |

Once you find a patent in the topic area that you are interested in each
patent must also reference similar past patents and you can unravel the
whole process by checking the references. In general it is best to search
for the newest patent in a topic area and all previous patents will be
referenced in the chain of reference patents. I used these key words in my
patent search: COUNTERFEIT, CURRENCY, and PEN and came up with about a
dozen patents.
It appears that there are various types of currency checker pens; however,
they all look for residue chemicals in the paper left over from the paper
manufacturing process. Starch and iodide salts are the most common compound
that all the pens look for and some pens claim to also look for other trace
chemicals. Most, but not all, genuine currencies , use a special
manufacturing processes that does not leave trace chemicals such as starch
in the paper..
ANSWER:
Counterfeit currency checking pens use chemical color indicators to sense
trace chemicals left in the paper from the manufacturing process. Most
governments use special paper manufacturing processes that do not leave the
same trace chemical residues. Starch and iodate salts seem to be the most
common trace chemical residue tested for in commercial paper.
DETAILS:
The following is a typical pen advertisement at the following URL:
