(1) Look: First, look at the color, pattern, pattern and printing effect of banknotes. The front and back of real yen banknotes have fine lines, rich layers and strong three-dimensional sense, and the bright and dark parts naturally transition. The second is to look at the color of yen paper. Yen paper has a unique technology and is light yellow. The third is to look at watermarks and braille marks. Looking at the light, the yen watermark is very clear, rich in patterns and strong in three-dimensional sense. At the same time, you can also see the braille marks clearly. The fourth is to look at optically variable denomination numbers and invisible patterns. Change the face value of 2000 yen, and observe whether the face value number in the upper right corner of the front changes from blue to purple, whether there is an invisible face value number "2000" in the pattern in the lower left corner of the front, and whether there is an invisible letter "NIPPON" in the green shading in the upper right corner of the back.
(2) Touch: Touch the paper first: Japanese yen paper is tough and stiff, but it is not slippery, dense or brittle to the touch. The second is to touch gravure patterns and braille marks: there is a clear sense of concavity and convexity.
(3) Listen: Shake the paper money by hand, the real paper money will make a crisp sound, and the counterfeit money will make a dull sound.
(4) Measurement: Use tools such as ultraviolet lamp, magnifying glass and magnetic detector to detect the professional anti-counterfeiting features of Japanese yen. Under ultraviolet light, the yen paper has no fluorescence reaction, and at the same time, it can be seen that the seals on the front and back of 2000 yen have bright fluorescence reaction. Miniature characters are printed on the front and back of the yen. Observing with a magnifying glass, the micro-character lines on real coins are full and clear. Use a magnetic detector to detect whether the intaglio patterns on the front and back of the yen have a magnetic reaction.
