Fake Bill Detector

Fake Bill Detector is a practical reference app that helps you inspect banknotes step by step and learn what security features to look for. It is designed as an educational aid and does not certify whether a banknote is genuine.

Explore the tools and reference library to:

- Follow a guided review for selected banknotes.
- Use the UV-style light viewer to inspect details in darker conditions.
- Use the multicolor watermark viewer to help visualize watermarks and paper features.
- Browse currencies by country and open security information for each banknote.
- View reference images, security features and official source links where available.
- Save check history and favorites for quicker access to previously checked banknotes.
- Choose your preferred app language or follow your phone's language.

The app is a support tool, not a professional authentication device. A phone screen cannot replace a certified ultraviolet lamp or examination by a qualified professional, and results may vary with the banknote, its condition, the device and ambient light. Use the information as a reference and compare the banknote with a known genuine example.
