Banknotes and coins

Security measures

Euro coins are produced according to highly advanced technical specifications which make them extraordinarily difficult to counterfeit and to facilitate the detection of any counterfeits.

They incorporate electromagnetic and automated reading characteristics which guarantee maximum security, as well as ensuring that they can be used in vending machines throughout the euro zone, regardless of the issuing member state.
