Fake currency and virtual currency English

1.

Take the new version of RMB 100 in 2015 as an example:

1. The light changes to the safety line of hollowed out windows, which is a great feature of the new coin. On the right side of the coin, it appears magenta when viewed directly, and turns green when squinted. When viewed through the light, you can see the word "100" alternately

2. When you look at the number, you can see the word "100" in the center of the coin, which is very conspicuous. When you look directly at the word, it appears golden, when you look directly at it, it appears green, and then it alternates between yellow and green with different angles of view

3. Look at the portrait watermark. The portrait watermark is in the blank on the left side of the coin front. Here we can see the clear head of Chairman Mao through the light

4. When we look at the offset printing pattern, we can see that 100 words are printed in the lower left corner of the front and the lower right corner of the back. Through the light, we can see that the front and back are superimposed together to form a complete 100

5. Looking at the left and right horizontal and vertical numbers, there are horizontal and vertical numbers in the lower left corner of the front and on the right side of the front, respectively. The horizontal top word and the first two numbers in the lower left corner are red, the last six digits are blue, and all the vertical numbers on the right side are blue

6. Look at the white watermark. The white watermark is located in the area below the horizontal number in the lower left corner of the front, and the clear 100 words can be seen through light observation

The engraving technology is applied to the people's Bank of China, the head of Chairman Mao, the national emblem on the front, the 100 numbers in the upper right corner and the Great Hall of the people. It is engraving gravure printing, so it has obvious concave convex feeling

extended information:

in fact, the Ministry of public security and other departments have special personnel to monitor and track the counterfeit currency that may appear in the market. According to their current monitoring and mastering situation, the simulation level of counterfeit currency is not high, and it is absolutely not up to the level of using fake money to confuse real money

although the means of making fake RMB are constantly improving, there are still differences compared with real RMB. I can responsibly say that in front of professionals and machines, there is no place to hide the existing counterfeit money

some counterfeit RMB were found, which were imitated by watermark, security line, color changing ink, micro text and other counterfeit technologies. The criminals use the method of directly using light ink to cover the watermark pattern on the back of the fake RMB, and the security bar is not true. These tactics are very crude and clumsy in the eyes of experts, but they are deceptive to ordinary people

2. Take one out of 101 pieces at random, and divide the remaining 100 pieces into two stalls, 50 for each stall.; Put it on both ends of the scale
first, if it is balanced, it means that the 100 pieces are all real coins, and the one taken out is fake. At this time, just take one out of the 100 pieces at will and weigh them on the balance, then you can tell the weight of real or fake coins
2. If it's unbalanced, you can take out 50 coins at the heavy end and divide them into two stalls, 25 coins for each stall. Put it on the balance for the second time:
1. If it is balanced, it means that the counterfeit is on the lighter end, and the counterfeit is lighter than the real one
2. If it is unbalanced, it means that the counterfeit money is heavier than the real one
3. (similarly, it's the same to analyze the lighter end.)

3. 1、 With the development of modern science and technology, the types of counterfeit and altered coins are increasing. At present, the counterfeit and altered RMB found in China can be roughly divided into the following categories:
(-) counterfeit currency: refers to all kinds of counterfeit banknotes that are copied from the original of the real currency and illegally reproced by various means. According to the means and methods of counterfeiting, there are the following types:
1. Counterfeit money hand painted or hand engraved. This is a kind of counterfeit money with backward means and poor quality. It is printed by hand engraving plastic and wood plate making. The forged counterfeit money is of poor quality. This kind of counterfeit currency exists all over the country, and the incidence is very common. Specifically, the number of each kind is not very large. It is characterized by backward means of forgery, poor plate making materials, and common writing paper and ordinary offset paper in the market; Pigment is also a kind of painting pigment sold in the market, so the counterfeit money is of poor quality and easy to identify. The victims are generally farmers with lower ecation level, self-employed, small traders, the elderly and children
2. Counterfeit money forged by ordinary office tools. This kind of counterfeit money is most common is to use black and white or color copier , its main feature is that the line is generally not smooth and neat; Especially with a magnifying glass, you will find that there is a burr, and there is a small amount of toner in the blank position. Some high-quality copiers, out of the counterfeit on the color is similar to the genuine, with a certain degree of deception. However, as long as careful identification is easy to find. Because this kind of counterfeit money is generally rough, and the main characteristics of the difference is obvious. Because the printing process of the copier and the toner used are completely different from the ink used by the banknote printing factory, the difference between the copied procts is also obvious. Because the copier uses the principle of static electricity to the toner in a certain position after being sensitized, which is different from printing. Secondly, because the copier uses solid powder and ink formed by baking and melting, the lines are not very smooth and neat. The printed lines are smooth and neat, and the color is uniform. Even if the quality of the is high and the lines are clear to the naked eye, a small amount of toner can be observed in the blank. After mastering these characteristics, we can identify the copied counterfeit money more accurately
3. Counterfeit money made with small printing equipment. This kind of counterfeit money is mainly made by photographing and relief printing. Its quality is more refined and it is more deceptive than manual description. However, e to the backward equipment, the printing conditions and raw materials used are limited to a certain extent, which is inferior to the real currency. But at present, the printing instry in China is developing rapidly, especially some small printing factories of township enterprises are also involved in printing counterfeit money. The counterfeit money printed by this kind of printing house is more deceptive
4. The so-called mechanism of counterfeit money, is the use of modern plate printing equipment forged currency. In recent years, several large cases of counterfeit currency have been found, which do great harm to the society. This kind of counterfeit currency mainly flows in from Hong Kong and Taiwan. It is quite lifelike and has many editions. As long as we master this difference, it is not difficult to identify this kind of counterfeit currency. For example, the "watermark" of this kind of counterfeit money is mostly printed, which can be seen without light transmission. Its paper will emit fluorescence under the purple light, and its lines are mostly dot structure. In 1983, the counterfeit 10 yuan offset note imported from Hong Kong was found in Guangdong, in August 1987, the counterfeit 100 yuan offset note was found in Shenzhen, and in March 1991, the counterfeit 100 yuan offset note was found in Beijing. Because of its high quality, this part of counterfeit currency is difficult to identify. According to our information, there are mainly three types
① Taiwan version of the third set of RMB 10 yuan coupon and RMB 1 yuan coupon. Its printing and plate making processes are similar to those of banknote printing factories in China. From the outside, it is also very similar to the real coin, such as gravure printing handle, pattern and color; From the paper, there are also watermarks. It is difficult to identify. But this kind of counterfeit money also has its obvious characteristics. For example, the picture of hand carved portrait is not consistent with that of real money, so it needs to be carefully observed with a magnifying glass. Another difference lies in: first, the quality of the paper is different from that of the real money. For example, the real money can make a crisp sound when it is brand new, while the sound of the fake money is relatively ll. The smoothness and straightness of the paper are not as good as the real money. Second, the Tian'anmen Square watermark on the fake ten yuan voucher paper is slightly less clear. Third, the color of the ink is not exactly the same. For example, the red color on the back of the ten yuan coupon is not exactly the same. Fourth, the connection technology of Plano relief plate. If you look closely, you will find that this technology is not used in the Taiwan version of counterfeit currency. The most important difference is that the real coin is well connected when it is not connected to the wiring. If you master this point, it is easier to identify
② Hong Kong version of the third set of RMB 10 coupons. This kind of counterfeit currency is completely offset printing, which is characterized by no gravure printing effect, very smooth handle, and no prominent gravure printing effect of real currency. In the design is continuous line structure rather than dot structure, this is mainly not using ordinary offset color separation, but manual color separation. There is a big difference in the color change parts. Another point is that the image landscape of gravure printing parts is seriously distorted through the process of photographing and plate making. That is to say, the color of the picture is deeper and lighter. The paper is ordinary offset paper, has a bright fluorescence. From the watermark, it is printed on the front with a kind of approximate white ink, and the watermark is very dark under the purple light< (3) 100 yuan counterfeit currency. At present, a large number of counterfeit 100 yuan coins have been found: one was found in Shenzhen in August 87, the second in Beijing in March 88, Jiangxi in September 1998, Henan in May 2000 and Guangdong in June. From the perspective of forgery means and characteristics, these counterfeit coins are basically the same. But it may not be a set of editions, there are some slight differences. Their main features are as follows:
firstly, the common offset paper is used. There is obvious fluorescence under the purple light, and the watermark on the face is printed on the back with light color ink, which is obviously different from the real ticket. Especially when you observe under the purple light, you will find that the watermark printed on the light ink is dark, and it is dark when compared with the fluorescence of the paper itself. This is easy to identify when compared with the human image watermark on real banknotes
secondly, it is overprinted by four-color offset printing with photographic or electronic color separation. This kind of counterfeit currency has the largest number, high level of forgery and the greatest risk. Its forgery means is the most conventional offset plate printing method. One of the characteristics is that the figure picture and the flower pattern is the network structure. Its color is overprinted with yellow, red, blue and black, while RMB printing is printed with the same color of ink. So the color pattern of RMB is linear structure. Secondly, the watermark is made by pasting paste between two layers of paper and pressing the watermark head image with a mold. The watermark is thick in paper
thirdly, the safety thread is made by pressing the plastic thread in the second layer of paper, and the knot is missed e to uneven cutting. In addition, the number of counterfeit currency is printed repeatedly. After recognizing these characteristics, it is easy to identify offset counterfeit money
5. Counterfeit money copied with chemicals. It is usually called rubbing coin. It is characterized by less ink and light. The design is delicate, as if washed, which is deceptive to ordinary people
(2) change coinage: refers to the false currency that changes the quantity and form of the original currency on the basis of the real currency or with the real currency as the basic material by means of mending, splicing, erasing and stripping, so as to realize the appreciation. Its main feature is the incomplete face. For example, the patchwork coupon is made up of several pieces, the page opening coupon has no front or back, and the mending coupon is the alteration of the number and text of the coupon< Second, the identification method of genuine and counterfeit RMB should be carried out on the premise of being familiar with the characteristics of genuine RMB and the main anti-counterfeiting technology. The main identification methods are as follows:
1. So far, the vast majority of counterfeit coins we have found and cracked are found by this method. Therefore, this method is more effective in identification
1. Look at: check whether the watermark is clear, layered and three-dimensional; Look at the safety line; See if the whole face pattern is single or partial color; Look at the miniatures and invisible denomination numbers< (2) hand touch: for example, the fourth set of RMB 2-plus coupons all adopt intaglio engraving printing technology, and touch whether the lines of the text and main pattern parts on the face have concave convex feeling
③ ear listening: banknote paper is a special kind of paper, which is crisp and rable, and can make a crisp sound when shaking with hands
2
1. Using thin paper and soft pencil to expand the watermark outline
measure with ruler: measure the size of banknotes with ruler. For example, the fourth set of RMB:
100 yuan coupon specification: 165x77 (mm)
50 yuan coupon specification: 160x77 (mm)
the fifth set of RMB:
100 yuan coupon specification: 155x77 (mm)

when it is difficult to identify the authenticity with the above methods, it is necessary to identify with the help of detection instruments. The simple thing is to observe with a magnifying glass to see if the lines and patterns are the same as those of real coins. Magnetic detector and violet lamp can also be used to detect whether there is magnetic reaction in the magnetic imprint, colorless fluorescent pattern can be detected under the violet lamp, and whether there is abnormal fluorescent reaction. For example, the fifth set of RMB 100 security line security measures are micro text and magnetic, horizontal number has magnetic, two kinds of color fiber are red and blue

5. Generally, they go to Yuesao company, Yuesao service center and other institutions to invite Yuesao, but generally, Yuesao is not provided in the confinement center,
because the confinement center is a special place for pregnant women to provide confinement service, and there are professional nutritionists who are responsible for providing confinement meals for pregnant women, helping them recover as soon as possible, providing feeding knowledge, and professional nurses to take care of their babies
