1. Feel:

Banknotes are made of pure cotton wood pulp and feel brittle and strong. Printing uses letterpress plates, and you can feel the ink protruding when you touch it with your hands. The note has a seemingly discontinuous curve in its upper left corner. Security thread, euro symbol and face value numbers, watermark.

2. Look:

Have you noticed the upper left corner of the banknotes? There are several seemingly incoherent curves there. In fact, as long as you hold the banknote up to the light, you can see that the curves on the front and back of the banknote constitute the face value of the banknote. The curves of counterfeit currency may be misaligned due to printing quality. In addition, the watermark is usually the first thing everyone sees, so I won’t go into details. There is also the security line in the middle of the banknote. It is relatively wide and is pressed into the paper. When you look at it against the light, you can see the "euro" and the face value of the banknote. Finally, there is a shiny silver place on the right side of the money. If you look at it against the light, you can see the laser-drilled euro symbol and face value numbers.

3. Tilt:

It is still the shining silver place. If you tilt it, you can see a hologram composed of face value numbers and patterns. In addition, the number in the lower right corner of the back of the banknote is made of color-changing ink, which changes from purple to olive green or brown when tilted.

Additional anti-counterfeiting measures include:

Microprinting: Use a magnifying glass to look at the EYPΩ (Greek for euro) on the front of the banknote, and you will find that there are many small words printed inside. If these guys are very unclear and look like pixels in the photo, then 80% of them are fake banknotes. There are other similar small prints on the banknotes, so you can look around for them.

Use UV lamp to check: If you put the banknotes under the UV lamp, it will not emit light (because the banknote printing paper will absorb UV rays). There are colored fibers in the banknotes, which will emit light under the UV lamp. Glowing down. The EU flag in the upper left corner looks green with orange stars. The signature of the President of the European Central Bank next to the flag will turn green, and the stars on the front will also glow.

The last bit of knowledge: Those small circles on the front of the banknote (each face value has a different color. For example, 10 yuan is orange, 20 is yellow, and 50 is also yellow) is called eurion constellation, which is used To prevent copying and scanning banknotes. If you put banknotes into a color copier, the copier will automatically recognize these small circles, and the final print will make it obvious at a glance that it is not a banknote (for example, one color is missing). Software such as photoshop can also recognize these small circles and warn users not to copy banknotes.
