The way to distinguish the authenticity of the euro is as follows: Signature: At first, the signature of the president of the European Central Bank was printed on the front of the euro paper money. In 2002, the signature of the first president, win duisenberg, began to appear on paper money, and was later replaced by Claude Trichet's signature. Until March 20 12, the euro banknotes with the signature of the current President Mario Delakis began to be issued. Security measures: Euro banknotes include many complicated security measures, such as watermark, infrared ray, holographic image, ultraviolet ink, micro-printing, etc. , to ensure the authenticity of banknotes. In order to let the public distinguish the authenticity of banknotes, the European Central Bank announced some security measures. However, under the euro system, the central bank keeps the complete security measures of euro banknotes strictly confidential. There are several ways to tell the authenticity of euro notes:

1) feel: the paper is tough and fragile after being treated with special materials; Gravure printing, the main pattern on the banknote, the large numbers representing the face value and the acronym representing the European Central Bank, gives people a sense of concavity and convexity;

2) Observation: Watermark, the paper money is watermarked, and the pattern includes the face value of the paper money and the windows of European buildings in different periods. Observing under the light, the original blurred pattern becomes clearly visible; Observing the security line under the light, you can find a magnetic black line in the middle of the banknote. In the middle of the black line is printed a transparent word "Euro" and its corresponding face value; When observing the print-up under the lamp, you can see that the incomplete figures in the upper left corner of the front and the upper right corner of the back of the banknote are combined into one, representing the face value of the banknote;

3) Tilt: holographic image, with a holographic image band on the right side of the front of the 5 euro, 10 euro and 20 euro notes. The face value of paper money, EU flag, euro symbol and "euro" can be seen by repeatedly tilting up and down; There is a holographic image label on the right side of the front of the 50-500 euro banknote, which is printed with the face value of the banknote, the micro "Euro" and the main pattern on the front of the banknote.
