How to distinguish the authenticity of the euro? \x0d\To distinguish authenticity, you should first understand Euro banknotes. Euro banknotes have 7 denominations, namely 5 euros, 10 euros, 20 euros, 50 euros, 100 euros, 200 euros and 500 euros. The larger the denomination, the larger the size of the banknote. The patterns on the front and back of these banknotes are doors, windows and bridges in various styles. Doors and windows represent openness, and bridges represent communication. The pattern also includes a map of Europe, the EU flag and the signature of the President of the European Central Bank. Here Oulan introduces to you three methods to identify genuine and counterfeit euro banknotes. \x0d\　The 5-euro banknote is gray, with a length and width of 120 mm and 62 mm respectively. The architectural styles on the front and back are both classical. The 10-euro banknote is red, with a length and width of 127 mm and 67 mm respectively. It has a Roman-style door on the front and a corresponding Roman-style bridge on the back. The 20 euro banknote is blue, the length and width are 133 mm and 72 mm respectively, and the architectural style is Gothic. The 50 euro banknote is orange, the length and width are 140 mm and 77 mm respectively, and the building is in Renaissance style. The 100-euro banknote is green, with a length and width of 147 mm and 82 mm respectively. The patterns reflect Baroque and Rococo-style architecture respectively. The 200-euro banknote is ocher-colored, with a length and width of 153 mm and 82 mm respectively. The architectural pattern reflects the combination of steel and glass. The 500-euro banknote is violet, with a length and width of 160 mm and 82 mm respectively, reflecting the modern architectural style of the 20th century. \x0d\ The euro is printed using the most advanced anti-counterfeiting technology in the world, making it one of the safest currencies in the world. Although there are many technologies that require special instruments for identification, for daily users of euros, they can easily identify authenticity by mastering the following three points. \x0d\　\x0d\The first method: Eye observation method\x0d\ When you observe the Euro banknotes against the light, you can see the watermark consistent with the pattern of the banknote and the watermark that reflects the number of the face value of the banknote, and you can see a security line in the middle. \x0d\　Second method: Hand touch method\x0d\　Euro banknotes are printed with a special kind of cotton banknotes. You can clearly feel the difference between this paper and ordinary paper by twisting and touching it with your hands. In addition, a special three-dimensional printing technology is used during printing, so you can feel the unevenness in certain parts with your hands. \x0d\　\x0d\The third method: tilt method\x0d\ When printing euro banknotes, a special technology is used. When the banknotes are tilted at a certain angle, a silver holographic image can be seen. Depending on the angle, the pattern changes. Different, respectively, are the euro symbol and the face value of the banknote. In addition, you can also see another holographic image when you look at it at an angle. This image has different colors depending on the face value.

There is another logo in the lower right corner of large-denomination banknotes (50, 100, 200, 500 euros), which is a holographic image of the face pattern and face value. This image can display different colors depending on the tilt angle.
