At present, there are many technologies to prevent counterfeit banknotes, and fluorescent lamps (ultraviolet lamps) are one of them. If counterfeit money uses that technology, it still won't work.

It is said that there are as many as eight anti-counterfeiting technologies. There must be at least five kinds of counterfeit banknotes. Such as paper, watermark, negative line, letterpress, fluorescence and so on.
