The Euro Money Tester Pen is a simple, portable device used to check the authenticity of euro banknotes. It contains a special iodine-based ink that reacts with starch found in most counterfeit papers.

How It Works:

When you mark a genuine euro note (made of cotton fiber), the pen leaves a faint or clear mark that fades quickly.

On counterfeit notes (often made from wood-based paper containing starch), the mark turns dark brown or black, indicating a fake.

Limitations:

Only detects starch-based fakes (not high-quality counterfeits).

Doesn’t verify security features like holograms or watermarks.

A handy tool for quick checks, but advanced counterfeits may require UV lights or other verification methods.
