In the age of digital money, the European Central Bank is stressing its commitment to cash through the launch of a new EUR50 note.
The EUR50 is the most widely used euro note - there are more in circulation than there are EUR5, EUR10 and EUR20 combined.
In May the ECB decided to kill off the EUR500 note over concerns that it "could facilitate illicit activities" but the central bank is keen to stress that it is still backing physical money.
Yves Mersch, ECB Executive Board member, says that the new paper "underlines the Eurosystem’s commitment to cash as a trusted and efficient means of payment".
To prepare for the introduction of the new note in April 2017, the ECB has signed up 500 industrial partners across Europe to ensure money handling machines and authentication devices are ready.
For security, the new EUR50 includes a transparent window near the top of the hologram that, when held up to the light, reveals a portrait of Europa, a figure from Greek mythology, which is visible on both sides of the note.
The front of the banknote also features an “emerald number”, a shiny number that, when tilted, changes colour from emerald green to deep blue and displays an effect of the light that moves up and down.
