Professional cash handlers include commercial banks, post offices and other organisations which sort cash and issue it to the public. Their work includes checking the banknotes and coins, and looking out for counterfeits.

The ECB publishes a list of machines and devices that have passed the test in order to help cash handlers and retailers choose a device to support them in authenticating euro banknotes.List of successfully tested banknote handling machines List of successfully tested banknote authentication devices
