Identification method of true and false virtual currency

1. There is no difference between true and false digital currency, and there is no difference between good and bad digital currency. Digital currency is just a tool, the key is to see who plays with it. Some people just use digital currency as a tool of pyramid selling, making money out of thin air, carrying out false propaganda and taking money away
if you don't understand digital currency, you'd better not touch it. The water of digital currency is very deep. Digital currency is even more chaotic, deception is repeated. If you are interested, you can first learn about the crowdfunding project token on coin Ying China platform.

2. Virtual currency is based on the virtual platform, so as long as the platform can confirm that the currency is real, the platform depends on the website, and as long as the website is identified, the platform can't be wrong

3. At this time, there are still people playing Shanzhai coin. They are full of energy and money.

4. Ancient coins (hard currency), that is, metal coins. It has been thousands of years in China to make currency with metal. The earliest metal coin is Baode copper shell of Shang Dynasty, which is more than 3000 years ago. Because the metal coin has the advantages of convenient use, wear resistance, long circulation life and so on. In addition to its own monetary function, it also has a very high art appreciation and collection function
method 1
look at the color. The real coin is nickel white, while the fake coin is also plated with nickel, but its nickel coating is thin, easy to rust and corrosion, and not wear-resistant. In addition, the material is different, so the color is dark and the difference is detailed; It is impossible for a real coin to rust. Once a rusty coin is found, it is likely to be a fake coin
look at the pattern. Generally speaking, the patterns of fake coins are rough and fuzzy. For example, the ears of wheat in the national emblem are fuzzy, the ribbon has poor sense of hierarchy, and the fine stripes are indistinguishable; The three-dimensional sense of Pentagram is also poor, not only the angle of Pentagram is long and short, but also the top is smooth; The strokes of Chinese characters and Pinyin letters on the front are thick, and the veins and stamens on the leaf petals of peony flowers on the back are blurred, etc
look at the picture and text center line. The picture and text center lines of one yuan real coins are facing each other; On the other hand, the false coins are often asymmetric; In addition, the thickness is uneven and the weight is relatively light; If you tap it, the sound is different from the real coin; What's more, the outline of a fake coin is slightly larger than that of a real coin. If you compare it with a real coin, you will have an obvious feeling
how to identify the real and fake coins
method 2
"touch": the pattern of the fake coins is often fuzzier than that of the real coins, and not as smooth as that of the real coins, especially the Chinese characters and pinyin on the back. The strokes of several fonts and Pinyin of the fake coins "people's Republic of China" are relatively rough, while the real coins are more delicate and delicate
"look": the national emblem of real coins and the word "one" are right, while many fake coins are crooked
"looking for": for coins after 2000, there are three letters of "RMB" on the side. Those who can't find these letters must be counterfeit coins
the difference between real coins and fake coins
first of all, if you touch a real coin with your hand, it will feel concave and convex, but if the edge of the coin is too smooth, it will be a fake coin
the second is to use the eyes. Generally speaking, fake coins have obvious rust or fuzzy patterns
in addition, if the above method is still unable to identify, you can go to the bank to use the instrument for identification. There is no basis for distinguishing the true from the false by the sound
then, how to distinguish between real and fake coins? Experts say there are two kinds of counterfeit coins: Casting and embossing. The key to identify forged coins is to look at them and listen to them
counterfeit coins are thinner and lighter than real coins, and some counterfeit coins are about a quarter thinner than real coins
the appearance of real coins is very regular, and the edges of coins are smooth and flat, while the fake coins are often not very regular, and the thickness is uneven, especially some of the edges of coins have burrs or unsmooth lines, and some of them have straight lines of files
the real coin pattern is clear, delicate, tall and straight, rich in layers and strong in three-dimensional sense, while the false coin pattern is fuzzy, the fine stripes can not be distinguished clearly, the five pointed star in the national emblem has poor three-dimensional sense, the five pointed star has different lengths,
the top is smooth, the leaf vein on the back of peony petals is fuzzy, and the peony stamens are fuzzy
the real coins have soft metallic luster, while the fake coins have white and ll metallic luster. Although some of them have luster, their luster is divergent. Some of them are like frosted coins with sand holes, which can be seen at a glance with a magnifying glass.

5. Cash detector, water pattern, gold thread, handle

6. The methods of intuitively distinguishing the authenticity of RMB can be summarized as "one look, two touch, three listen and four test":

"one look": one is to look at the watermark and look after the RMB in front of the light. For more than 10 yuan RMB, you can see the head portrait or flower watermark in the watermark window, and for 5 yuan banknotes, you can see the full version of ancient currency watermark. Second, look at the safety line. There is a clear straight line on the right side of the fourth set of RMB 1990 50 yuan and 100 yuan notes. The "safety line" of counterfeit money is either printed with light color ink, blurred, or manually sandwiched into a silver plastic line. It is easy to find silver white thread ends that have not been cut at the edge of the paper. The fifth set of RMB security line has miniature text, counterfeit words are not clear, lines are easy to draw out. The third is to see whether the color of the pattern on the banknote surface is bright, whether the lines are clear, whether the wiring is in good condition, and whether there is no blank or gap<

"two touch": as intaglio printing is adopted for RMB with denomination of more than 5 yuan, the lines form ink channels protruding from the paper surface, especially in Braille spots, "people's Bank of China", the fifth set of RMB portrait, etc. When you touch these places with your fingers, there is a distinct concave convex feeling. When you swipe the newer banknotes with your fingers, there is obvious resistance. At present, the collected counterfeit money is printed by offset printing, smooth, no bump

"three tins": RMB paper is specially made paper, which is firm and crisp, and newer banknotes will make a crisp sound when they are flicked by fingers. Counterfeit paper soft, thin, sound stuffy, not resistant to rubbing

"four tests": simple instruments are used for fluorescence detection. The first is to detect whether the paper has fluorescence reaction. The RMB paper has not been fluorescent bleached, and there is no fluorescence reaction under the fluorescent lamp, and the paper is dark. The counterfeit paper is bleached and has obvious fluorescence under the fluorescent lamp. The paper is white and bright. Second, there are one or two fluorescent characters in the RMB, which are light yellow. The fluorescent characters of fake RMB are not in the right color, and they are pale white

7. 1. Real banknote paper is a special coining paper with thin handle, and the whole banknote paper has no fluorescence reaction under ultraviolet light. Yellow blue fluorescent fibers are irregularly distributed in the coin paper, which can be seen by naked eyes in sunlight, and have fluorescence reflection in ultraviolet light. Counterfeit banknote paper is ordinary offset paper or ordinary writing paper, with thick handle and smooth surface. Under ultraviolet light, the banknote paper shows white fluorescence, and no yellow blue fluorescent fiber. But sometimes real money will also show white fluorescence under ultraviolet light, because the paper money is contaminated by substances containing fluorescent agents (the most common is daily detergent). 2. The patterns on the front and back of the printed real banknotes are engraved gravure printing, the hair of the characters is clear and distinguishable, and the lines are smooth and convex. If you feel carefully, you can feel the lines of each hair on the portrait. Counterfeit banknotes are flat printing and four-color overprint, so the pattern is unevenly inked and the texture is not clear. The hair of the special portrait is piled up by dot ink, so the hair can't be identified. The paper pattern of counterfeit banknote is also composed of dots. If observed with a magnifying glass of about 8 times, the straight lines or curves become the lines formed by small dots, which are disorderly. 3. Magnetic safety line real banknote safety line is magnetic, which can be identified by machine. It can be seen by naked eyes that there are miniature words (limited to 100, 50, 20 yuan) in the safety line, with clear words, orderly intervals and consistent width. It is difficult for the security line of counterfeit banknotes to be magnetic, although some words are not neat and the line is wide and narrow. Because it is laid by hand, the paper is wrinkled, and the plastic safety line is different from the paper's expansion rate, and the buried ground is not covered, resulting in a silver white dotted line at both ends of the safety line, which can be seen. 4. Watermark real banknote watermark is formed in the process of papermaking by squeezing the pulp before it is fully draught and dried. The light and dark layers of the image are formed according to the weight of the pressure, and the transition of the layers is natural, full of charm, the image is clear, and the three-dimensional sense is strong. The watermark of counterfeit banknote is made by hand with poor quality. At present, the known method of making paper includes uncovering the interlayer of the paper, coating a layer of paste in it, and then pressing the two layers of paper together. When wet, the paper is padded on the gravure plate engraved with images, and then pressed. Manual operation, clumsy action, resulting in a watermark side of the counterfeit paper wrinkled uneven. 5. The front back complementary printing pattern of the front back complementary printing of real banknote is the one-time printing of the front and back of the special equipment for banknote printing. The complementary patterns on the front and back are completely consistent and accurate in perspective. Counterfeit banknotes can be printed twice on the front and back of the banknote, and the patterns on the front and back of the banknote can't match each other. If the paper's expansion and contraction are added, the offset of the banknote will be greater, such as the dislocation of the patterns on the front and back of the banknote, the different width of the patterns or the overlapping of the patterns. 6. The colorless fluorescent ink shows a rectangular box "100 / 50 / 20 / 10 / 5" in the upper left corner of the real banknote under ultraviolet light, emitting strong orange fluorescence. Under ultraviolet light, counterfeit banknotes also have fluorescence reflection on the real banknotes mentioned above, but the color concentration and fluorescence intensity are far different, and they are dark and colorless. If the fluorescence is different, it can be compared with the real coin. 7. There is a "100 / 50 / 20 / 10" character under the number in the lower left corner of the front of the new banknote with light variable ink, which is printed with light variable ink (the new version of 5 yuan does not have this design). The normal viewing angle is grass green, and the visual or head up view is blue black. The color gradients ring the change of visual angle. In the proction of counterfeit banknotes, e to the lack of this special light variable ink, we had to use grass green ink to print the words "100 / 50 / 20 / 10" without changing color. 8. The invisible number new banknote has the invisible number "100 / 50 / 20 / 10 / 5" in the flower decoration at the bottom of "100 / 50 / 20 / 10 / 5" in the upper right corner, which can be clearly seen when the banknote is viewed horizontally from the right end. The words are composed of regular lines, which are printed by engraving gravure printing, and proce different visual effects when viewed directly or horizontally. Because the counterfeit banknote is printed by lithography, the lines are composed of dots, which completely destroys the visual effect of the designer's conception. Based on this, the authenticity of the banknote can be judged. Head up, no "100 / 50 / 20 / 10 / 5" invisible words of banknotes must be counterfeit. 9. The number of a real banknote is a measurement number. Absolutely no double, and neat, standard font, ink, color, pressure uniform, good quality. The real banknote number is printed by embossing, and there is an indentation on the back of the number part. The characteristics of counterfeit banknote numbers are as follows: most of the numbers are the same; The font is not standard; The color is different; Due to flat printing, there is no pressure mark on the back. 10. The lower left corner of the front side of the real banknote with magnetic ink adopts a two-color horizontal number (2-digit crown word and 8-digit number), which is magnetic and can be used for machine aided identification (the new version of 5 yuan does not have this design). The two-color horizontal number of counterfeit banknote is non-magnetic, but magnetic powder is often applied on the part when making counterfeit banknote to deceive the machine. Therefore, magnetic does not necessarily mean that it is real banknote, but non-magnetic must be counterfeit banknote. It should be emphasized that the above 10 anti-counterfeiting methods are based on the anti-counterfeiting features of the fifth set of RMB, so they are not suitable for the fourth set of RMB
adoption

8. The methods to distinguish the authenticity of RMB can be summarized as "one look, two touch, three listen and four test":
"one look": one is to look at the watermark and look after the RMB in front of the light. For more than 10 yuan RMB, you can see the head portrait or flower watermark in the watermark window, and for 5 yuan note, you can see the full version of ancient currency watermark. Second, look at the safety line. There is a clear straight line on the right side of the fourth set of RMB 1990 50 yuan and 100 yuan notes. The "safety line" of counterfeit money is either printed with light color ink, blurred, or manually sandwiched into a silver plastic line. It is easy to find silver white thread ends that have not been cut at the edge of the paper. The fifth set of RMB security line has miniature text, counterfeit words are not clear, lines are easy to draw out. The third is to see whether the color of the pattern on the banknote surface is bright, whether the lines are clear, whether the wiring is in good condition, and whether there is no blank or gap
"two touch": as intaglio printing is adopted for RMB with denomination of more than 5 yuan, the lines form ink tracks protruding from the paper surface, especially in Braille spots, "people's Bank of China", the fifth set of RMB portrait, etc. When you touch these places with your fingers, there is a distinct concave convex feeling. When you swipe the newer banknotes with your fingers, there is obvious resistance. At present, the collected counterfeit money is printed by offset printing, smooth, no bump
"three tins": RMB paper is made of special paper. It is firm and crisp, and newer banknotes will make a crisp sound when they are flicked by fingers. Counterfeit paper soft, thin, sound stuffy, not resistant to rubbing
"four tests": simple instruments are used for fluorescence detection. The first is to detect whether the paper has fluorescence reaction. The RMB paper has not been fluorescent bleached, and there is no fluorescence reaction under the fluorescent lamp, and the paper is dark. The counterfeit paper is bleached and has obvious fluorescence under the fluorescent lamp. The paper is white and bright. Second, there are one or two fluorescent characters in the RMB, which are light yellow. The fluorescent characters of fake RMB are not in the right color, and they are pale white.

9. The fifth set of RMB anti-counterfeiting measures (which should be the most comprehensive on the Internet):

1. Watermark: the fifth set is 100 yuan, 50 yuan is the fixed watermark of Mao Zedong's head portrait; 20 yuan for lotus fixed watermark, 10 yuan for rose, 5 yuan for Narcissus, 1 yuan for orchid. The 2005 edition has a white watermark denomination below the crown
2. Red and blue color fiber: on the face of the fifth set of RMB 1999, which is 100 yuan, 50 yuan, 20 yuan, 10 yuan and 5 yuan, you can see red and blue fiber in the paper 3. Security line: the fifth set of RMB 1999, 100 yuan and 50 yuan, is the security line of magnetic micro text; 20 yuan is the magnetic safety line with light and dark alternating; 10 yuan and 5 yuan are holographic safety lines for front window opening. The fifth set of RMB in 2005 is the holographic window safety line, with 50 yuan and 100 yuan windows on the back and 20 yuan, 10 yuan and 5 yuan on the front
4. Hand carved head: the fifth set of RMB banknotes with all denominations features Mao Zedong's head on the front, which are hand carved intaglio printing process, vivid, vivid and concave convex
5. Invisible denomination number: there is a decorative pattern on the upper right side of the front of the fifth set of RMB banknotes with each denomination. The face of the note is placed close to the eye, and the face of the light source is rotated 45 degrees or 90 degrees to see the Arabic numeral denomination
6. Light variable denomination number: in the fifth set of RMB 100, the denomination number "100" is printed on the lower left side of the front with a new type of ink. When viewed vertically from the face, it turns green, and when tilted at a certain angle, it turns blue. 50 yuan can change from green to red
7. Complementary patterns of yin and Yang: the fifth set of RMB has a circular local pattern in the lower left corner of the front and the lower right corner of the back, which can be seen through light. The front and back patterns form a complete ancient coin pattern. The complementary pattern of 1000 yuan and 50 yuan in 2005 edition is in the middle of the right edge of the left watermark area
8. Engraved gravure printing: the fifth set of RMB bank name, denomination number, Braille denomination mark, etc. are all engraved gravure printing, with obvious concave and convex feeling when touching with fingers. On the right side of the front main scene pattern of 1999 version 1 yuan and 2005 version, there is a set of lines arranged from top to bottom, which are printed by engraving gravure printing process, with a strong concave convex feeling when touching with fingers
9. Number (embossing): in the fifth set of RMB 1999, 100 yuan and 50 yuan are horizontal and vertical double numbers, the horizontal number is black, and the vertical number is blue; The other denominations are two-color horizontal numbers, the left half of the number is red, and the right half is black. 2005 edition 100 yuan, 50 yuan for two color heteromorphic number, big in the middle, small on both sides
10. Offset microfilm: the fifth set of RMB 100, 50, 20 and 10 banknotes is printed with the offset microfilm "RMB 100 & quot“ RMB50”、" RMB20"、“ Most of the words such as "RMB 10", "RMB 5" are hidden in the decorations
11. Special paper: the fifth set of RMB is printed with special raw materials and paper for banknote printing made by special ing equipment, without fluorescent reaction under ultraviolet light. Newer banknotes make a crisp sound when they are shaken
12. Color changing fluorescent fiber: in the fifth set of RMB, yellow and blue fluorescent fibers can be seen randomly distributed in the paper under the specific wavelength of ultraviolet light
13. Colorless fluorescent pattern: each coupon of the fifth set of RMB can be printed with colorless fluorescent ink, which can be read by machine
14. Color fluorescent pattern: the red lines in the oval pattern above the main scene of the fifth set of RMB 100 show bright orange under the ultraviolet light of a specific wavelength; The middle of the back of the 20 yuan coupon shows a green fluorescent pattern under a specific wavelength of ultraviolet light. The back of the 50 yuan coupon will also show a pattern under ultraviolet light
15. Offset wiring printing: the Chinese traditional pattern on the left side of the fifth set of RMB 100 is printed by offset wiring technology, and each line is composed of more than two colors
16. Gravure wiring printing: the largest denomination number on the back of the fifth set of RMB and the denomination number on the left side of the front are printed by gravure wiring technology, and the two ink colors are naturally integrated
17. Gravure micro text: the fifth set of RMB is printed with gravure micro text in the decorative pattern at the top right of the front. Under the magnifying glass, you can see "rnb100", "RMB20" and other words corresponding to the face value
18. Magnetic Number: detected by a specific detector, the black number in the 1999 version of 100 yuan and 50 yuan and the two-color number of 20 yuan, 10 yuan and 5 yuan are magnetic and can be read by machine

when judging the authenticity, there are still several points to pay attention to:
1. The 20 yuan coupon of 1999 edition is printed by single-sided gravure, and the back is completely offset printing, without concave and convex feeling, which is quite different from the 20 yuan coupon of 2005 edition
2. The quality of gravure ink used in the 2005 version of the 10 yuan coupon has problems, so the pedestrian line name, portrait and main scene pattern are easy to fade. But this kind of faded money is also very likely to be real money. This problem does not exist in other banknotes in 2005.
