This product is not guaranteed to detect all counterfeit bills - it should be used in conjunction with other counterfeit detection methods.

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 detects bills printed on normal copier paper instead of the fine papers used by the U.S. Treasury
