Can this detect fingerprints?

Not certain, but you can use a UV light to detect fingerprints, but on some surfaces, you need additional items such as powders, etc. to make them stand out. I would say it depends upon the type of surface, but this item does not claim specifically to be able to detect fingerprints from what I read.
