Banknote characterization using the FTIR spectroscopy

Counterfeit methods are more sophisticated than ever before, so it is necessary to implement as many different methods as possible to get reliable information on the origin of the banknotes. The FTIR spectroscopy provides exactly this, a different approach to the identification of different banknote components, from the paper itself to the characterization of the inks, holograms and watermarks. This paper examines the similarities and differences in the composition of the paper used for making banknotes in six different currencies, and at the same time deals with the characterization of the unique features of a particular currency. Moreover, the consistency within the particular currency is examined by comparing multiple banknotes of the same denomination.
