counterfeit pen
Bill authentication marker
A counterfeit pen is a marker used to detect fake currency.
The pen contains iodine-based ink that reacts with starch in wood-based paper, leaving a dark mark on counterfeit bills while appearing light or clear on genuine currency, which uses starch-free cotton-linen paper.
Cashiers routinely swipe bills with counterfeit pens at checkout: She ran the fifty through the counterfeit pen before making change.
