FT-IR Spectroscopy as a discrimination Method for establishing Authenticity of Euro Banknotes

The number of counterfeit banknotes in the world is increasing every year. Since it is much easier to forge banknote with a similar visual characteristic as the original than to produce a banknote with the identical chemical composition as the original, FT-IR spectroscopy is great solution for the genuine validation. The pa-per will look at the similarities and differences between counterfeit and original banknotes with respect to the materials used. The emphasis will be on euro banknotes ; therefore, the characteristic areas of the recorded spectra will be adjusted to the security elements of the given currency. The paper confirmed that FTIR spectroscopy is a suitable method for non-destructive measurements and allows for easy identification of counterfeits.
