Cash handling

Authenticity and fitness checking and recirculation of euro banknotes

The possibility of recirculating euro banknotes enables banks and other cash handlers to supply the currency in a more effective and cost-efficient manner. To ensure the integrity of the banknotes, the European Central Bank (ECB) adopted Decision ECB/2010/14 on the authenticity and fitness checking and recirculation of euro banknotes.

Decision ECB/2010/14 came into effect on 1 January 2011, replacing the "Framework for the detection of counterfeits and fitness sorting by credit institutions and other professional cash handlers". It was amended by Decision ECB/2012/19 of 7 September 2012 to extend its scope to the authenticity and fitness checking and recirculation of new series of euro banknotes and to clarify a few requirements, by Decision ECB/2019/39 of 5 December 2019 to allow the reprocessing of banknotes not clearly authenticated and to introduce of a new category of banknote handling machine, and by Decision ECB/2025/36 of 16 October 2025 to allow the reprocessing of suspect counterfeit euro banknotes. More
