Bank Note Checker Pen Counterfeit Fake Forged Money Tester Marker Detector - kenable

The pen's ink reacts differently with the paper used in genuine banknotes compared to paper used in counterfeit notes. This reaction results in different colors upon marking.

No, the pen is a supplementary tool and should not be the sole method of verifying currency. It is a quick check, but more sophisticated forgeries may pass the pen's test.

A black or brown mark indicates that the banknote is likely counterfeit.

A yellow mark that fades is a strong indication that the banknote is genuine.

The pen is designed for use on paper-based currencies. It may not work on polymer notes. Check the pen's compatibility for your specific currency type.

The ink life varies depending on usage. Replace the pen when the marks become faint or the pen stops marking the notes.

Store the pen in a cool, dry place, away from direct sunlight, and with the cap on when not in use.

Ensure the pen is uncapped and the tip is making contact with the paper. If the pen is new, try pressing the tip firmly. If it still doesn't work, the pen may be empty and require replacement.

Apply more pressure when marking the note. If the result is still faint, the ink may be drying out, and the pen may need replacing.

Real currency should leave a pale yellow mark that fades quickly. Fake currency will leave a dark brown or black mark that remains. If unsure, compare with a known genuine note or use additional verification methods.
