So my cousins and I went to 7-11 to buy snacks and drinks. Had one buy 3x $10 lotto tickets.
At first they wouldn't let him use his HSBC debit card. Then my other cousin tried using his $100 bill. The guy was flakey and used the marker... tried another $100 no go.. on both

Ended up paying with $20s

End of story... so is the ink suppose to change? It did not with the $100 =/

The counterfeit detector pen is extremely simple. It contains an iodine solution that reacts with the starch in wood-based paper to create a black stain. When the solution is applied to the fiber-based paper used in real bills, no discoloration occurs. The pen does nothing but detect bills printed on normal copier paper instead of the fine papers used by the U.S. Treasury.

whats supposed to occur is that if its legit it's a yellow/green-ish kind of line. if its counterfeit it should be a dark brown/black-ish color left on the bill.
