About this app

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.

USELESS!! The UV light doesn't work. I assumed this before hand as its not a colour. Its a light wave. So how is your screen supposed to replicate this. And if thats a lie. (and its the first option) then? Its just another useless app chock full of adds. An addfest. If I could score zero I would. My advice, look up the information required on your individual government sites, buy a cheap UV light (keyrings cost pennies) and use your own eyes and intelligence. Hope this helps somehow 🙂

This only detects watermarks on banknotes, in fact, you can easily see the banknotes' watermark when you hold it up to the sun or any light source. But, the UV ink detector doesn't work, even in the dark, it just does nothing, I wouldn't recommend this app.

Tried to run the check on a $50. App loaded an ad, crashed, restarted, and then proceeded to run a loop of flashing blue and yellow. Do. Not. Download.
