Fake Bill Detector

Check banknotes with UV-style light, watermark viewer and security info.

Fake Bill Detector is a support tool designed to help you inspect banknotes and learn more about their security features.

The app includes a UV-style light viewer optimized for dark environments, a watermark viewer, and an information section with details about security elements found in different currencies.

With this app you can:

Use a light viewer to observe details in dark conditions.

Check watermarks more easily.

Read security information about different banknotes.

Learn what details to look for when inspecting a bill.

Compare the results with known genuine banknotes.

Important: a phone does not replace a professional ultraviolet lamp and cannot guarantee whether a banknote is authentic. Visibility may vary depending on the country, banknote type, condition of the bill, device screen, camera and ambient light.

For best results, use the app in a dark place and test it first with a genuine banknote so you know what details to look for.
