With the improvement of people's living standards, more and more people like to travel abroad. In Japan, people rarely see local shops using money detectors, which is very puzzling. In fact, the reason is very simple, that is, there are almost no counterfeit banknotes in Japan for the following three reasons: first, the cost of printing counterfeit banknotes is very high; Second, the Japanese people are honest; Third, Japanese money detectors are confidential.

First of all, judging from the process of printing money, the manufacturing process of Japanese currency is very complicated. Japanese currency paper is a kind of synthetic paper, which is mixed with a kind of pulp called three-eye tree, so that the paper money will be slightly yellow, and at the same time, anti-copy ink will be used on the paper money, and there will also be an anti-copy dot on the character image above and a holographic pattern on the lower left. It is precisely because the manufacturing process of counterfeit money is so complicated, time-consuming and costly that people don't want to make counterfeit money.

Secondly, people are honest. The state has made great efforts to crack down on counterfeit goods, and there are few counterfeit goods in Japan. The quality of goods is guaranteed, which is one of the reasons why people like to go shopping in Japan. Any Japanese who violates honesty will be severely punished. They need to apologize to the people of the whole country, and they will also be discussed by the people. There was once a college student who faked his thesis and his tutor committed suicide in the institute. It can also be seen that Japan's moral condemnation of counterfeiting is much more serious than facing jail.

? The last reason is that the Japanese money detector is confidential, because the technology that can completely prevent counterfeit money from being copied has not been invented in the world at present, so some people will still take advantage of the loopholes to print counterfeit money. As the saying goes, it is indispensable to prevent people. Although money detectors are rarely seen in Japan, it does not mean that they are not used. On the contrary, there are many printing presses in Japan, but most of them are in very secret places. For example, machines with coin-operated functions, some vending machines and cash registers have the function of checking banknotes, and the banknotes or steel shovels put in are all verified.
