How do Japanese airport inspectors detect fake passports and visas?

In recent years, the way of international smuggling has changed a lot. Illegal immigrants used fake passports and visas to "break through customs" at the airport, replacing the previous smuggling by boat. For those who enter the country illegally with fake passports, the most difficult thing is the Narita Airport Branch of the Tokyo Immigration Bureau. Last year alone, more than 265,438,000 fake passports and visas were discovered. At the same time, more than 8,400 foreigners with problems were refused entry and repatriated. In addition, it also helps the police to identify all kinds of forged documents. Narita's entry into the tube not only makes illegal entrants panic, but also makes people feel mysterious. So, how did the censor who entered Narita identify fake passports and see through illegal immigrants? Narita Airport is the largest international airport in Japan, with passengers accounting for more than 60% of Japan's total. Last year, it was 26.49 million person-times, and this year there were 866,000 person-times in the "Golden Week" alone. In order to keep illegal immigrants who use fake passports and visas out of the country, Narita set up a "Counterfeiting Document Room" at 1999, which was staffed and purchased the most advanced equipment in the world, specializing in the authentication of passports, visas and other documents. According to the director of the Counterplan Office for Forgery and Alteration of Documents, the most common fake passport at present is the "shaved passport", that is, illegal immigrants stick their photos on other people's passports. Narita sees through a large number of illegal immigrants with "shaved passports" every year. Although there is no such machine that can detect the authenticity of a passport and visa, no matter how smart the counterfeiters are, they will leave traces of fraud. For example, the film with photos of illegal immigrants can't be pasted right on the position of other people's passport photos. As long as you examine it with an electron microscope, you can still find traces of fraud. Recently, criminal organizations have become more and more sophisticated in forging fake passports. Some fake passports, like Japanese passports, are directly printed with photos, so these fake passports can't be identified at a glance as before. Therefore, the countermeasures and skills to identify true and false should also be kept up accordingly. In fact, there are not many examples of finding illegal immigrants by checking the authenticity of passports. Most illegal immigrants found by immigration inspectors still pass immigration inspection and find problems according to each other's answers and actions. Every examiner has to deal with hundreds of passports every day, which requires mastering the basic common sense of distinguishing authenticity and accumulating experience in distinguishing authenticity. Therefore, it is very important to train experts in this field. In addition to the daily training experience at the inspection site, inspectors should also participate in technical training and learn the latest appraisal methods. Checking the authenticity of a passport depends on both professional knowledge and practical experience.
