MacDonald's so-called hard-to-imitate anti-counterfeiting technology includes the following: The first is actually a very traditional anti-counterfeiting technology: watermarking.

Watermark refers to the formation in the papermaking process, "sandwiched" in the paper rather than on the surface of the paper, and can clearly see the graphics, portraits or words with light and dark textures when facing the light, it is made by changing the density of pulp fibers in the production process of paper. This technique was developed very early, around the end of the eighth century, during the Tang Dynasty in China. However, although this technology appeared early, it was quite easy to use, and until the twenty-first century, the paper of various countries. This technique is still commonly used on coins. Because although this technique is simple, it is really difficult to do it well. To ensure that every watermark in the paper is exactly the same, just like a seal printed, it is quite difficult in production technology. At least it's not easy to do this in a small private workshop or something. It also took a lot of effort to solve the problem of how to make a clear, delicate image and consistent watermark in a stable manner.

Another anti-counterfeiting trick is special ink. These inks use a very unique formula, which has been tested nearly 10,000 times, and has a unique light green color, and the performance is quite stable, and it is extremely difficult to make such a color without a formula. And some fluorescent substances are also added to these inks, so that the banknotes that use this ink. The ticket fluoresces when illuminated by ultraviolet light. Of course this is only for professional bodies to identify the real and fake. means of coins.

Another key means is the unique banknote. Ticket paper. The paper used in the Federal Reserve Gold Dollar Bills is unique in terms of material and workmanship, and it also uses the process of inlaid metal wire, which was not used in this era.

However, Morgan's real concern is not about these technical issues. Rather, it was Scrooge's vision of how to use the right to issue banknotes in the future.

"My dad thinks that even for a long time, we still have to keep a one-to-one reserve of gold, and there will be a lot of benefits in our hands. For example, we can control the total amount of money circulating in the market through guò, and the benefits of this are so great. And the most important thing now is to convince the American people that only the Fed's gold dollar bills are truly reliable. ”

Thompson-Harris Bank is a Texas-based bank that has the authority to issue notes but is not part of the Federal Reserve Bank. Bankers in the Midwest are always suspicious of the big capitalists in the East. The bank's owner, Thompson, and his partner Harris are no exception.

That morning, an accountant hurriedly found Tom Puson.

"Mr. Thompson, there's something unusual, and perhaps I should report it to you." Accountant Du Gao said.

"Ah, Mr. Dugaux, what's going on?" Thompson looked up from behind his desk, looked at Du Gao, and said gently.

"Mr. Tong Pusun, in the past month, many people have taken the gold dollar coupons issued by the Bank to exchange for gold. The number of each transaction is not much, but the total number is much higher than the previous period, almost 10% higher. ”

"Oh, in the current state of the economy, the number of people who have exchanged huàn gold has risen so much, which is indeed not right. Count jù and let me see. Tomson said.

Du Gao handed the counted numbers to Tang Pusun, who looked at them carefully, except for the amount of gold exchanged for huàn, the other numbers were normal.

"The current economic shape is not bad, there shouldn't be a lot of gold." Tomson furrowed his eyebrows in confusion.

But Thompson's doubts didn't last long, as the answer was given in Texas newspapers two days later. In the newspaper "The Texan" published such a news:

"Texas police have cracked the largest case of counterfeit gold dollar coupons in history. The main culprit was killed on the spot, and the police seized counterfeit gold dollar bills issued by the 'Thompson Harris Bank' with a face value of more than $500,000 at the scene. According to Sheriff Hunter, who was in charge of the case, the counterfeit coupons were so realistic that if they had not known in advance, and that they had seized all the equipment used to forge the coupons at the scene, and that some of the accomplices had confessed to the crime, he would not have been able to determine whether the seized coupons were genuine or fake. Even if the real and fake gold dollar coupons are mixed together, even the police professionals cannot distinguish them. According to the accomplices' confessions, they probably made millions of gold dollar coupons, and these forged gold dollar coupons were all transported by the main culprit Simpson, and no one knows the specific whereabouts, and no one knows how many of these forged gold dollar coupons have entered the market. But the estimated amount will not be less than three million dollars. ”

This news gives answers to questions that puzzle Thompson, and apparently many of the extra gold dollar coupons that have cashed in gold this month have been forged by those damned criminals!

However, Mr. Tomson hoped that himself, and the others, did not know the answer, because it meant only a run. Because of that kind of pseudo. Banknotes are so realistic that they are almost impossible to identify. All people who hold this kind of gold dollar coupon will worry about whether the gold dollar coupon in their hand is real or fake. The easiest and safest way to do this is to go to the "Thompson-Harris Bank" that issued it to convert it into gold, when the banks can't tell the difference.

And according to the police, these criminals created a pseudo. At least $3 million worth of banknotes have already flowed into the market, and damn it, Thompson Harris Bank's net worth is just $2.5 million. These damn pseudos. Banknotes, combined with real gold dollar bills, would definitely have bankrupted the bank.

Just as Thompson had expected when he saw the newspaper, when he arrived at the bank, he found that there was already a long queue in front of his bank. Apparently these people are here to exchange huàn dollars for gold coins.

As soon as they saw Thompson, the blank Harris and Dugo ran over.

"Mr. Tom Puson, what can I do about this?" "If this continues, our coffers won't last long." ”

"Is there a way to tell the real from the fake?" Thompson asked.

Everyone shook their heads.

"Can't our experts identify it either?" Tomson is not dead yet.

Shake your head wordlessly again.

"Then stop redeeming huàn for the time being, and then find a way to identify it!" Thompson said.

……

A few days later, Thompson was almost ten years older. In order to identify the fake. banknotes, he obtained from the police all kinds of techniques for those criminals to forge gold dollar coupons, including ink, including paper and other things. Moreover, the police found a set of fake . The key things of the banknote, including the engraving, including the ink formulation, including the manufacturing process...... What's even more terrifying is that these things are almost exactly the same as the gold dollar bills issued by their banks. Even if there are some differences, they are reasonable errors within the standards they set. That is to say, real banknotes and fake. Banknotes are completely indistinguishable!

……

In the end, this turmoil not only led to the bankruptcy of Thompson Harris Bank, but also put the entire banking community in danger, and almost all the banks that issued gold dollar bills were nervous. And the people's trust in the gold dollar coupon has also dropped significantly. It's just that the gold coin is too troublesome, otherwise, there are legislators who want to abolish the gold dollar coupon.

It was in the midst of this panic that the Federal Reserve publicly launched their brand new gold dollar bills, which were said to be absolutely impossible to imitate.

"Ladies and gentlemen, this is the gold dollar coupon we launched this time, and these gold dollar coupons come in the following denominations...... As for the anti-counterfeiting issue that everyone is most concerned about, we have carried out in-depth cooperation with the University of Cleveland's Dashi Yàn Office, and use the latest anti-counterfeiting technology on this gold dollar coupon, which is by no means forged by any individual, or even any country. At the launch of the new gold dollar bills, the Fed's spokesman Paul Joseph introduced the supposedly unforgeable gold dollar bills.

Subsequently, someone sent the sample to each reporter to see, and all the reporters who participated in the issuance were surprised by the exquisite printing of the Federal Reserve gold dollar bills, the clear watermarks, the vivid colors, and the uniqueness of the paper. But the most surprising thing to them was that when the lights went out, Paul Joseph turned on a very dim electric light, and the Fed gold dollar bill in his hand emitted a mysterious fluorescence under this lamp!

Seeing this scene, almost all reporters had considerable confidence that the new gold dollar coupons could not be forged. And a week later, with the release of the new gold dollar coupon, almost all newspapers began to praise this beautiful, almost impossible to forge gold dollar coupon. There are newspapers that call it human paper. The greatest work of art in the history of coins. And the experts in various universities, research departments and other institutions who study anti-counterfeiting technology also praise the anti-counterfeiting ability of this gold dollar coupon in unison.

"The paper used in this kind of gold dollar coupon has a particularly special feel, even a blind person can easily distinguish this paper with this unique feel. Coins and counterfeit paper in general. Currency. Watermark almost all banknotes. There are tickets, but it is very difficult to make the watermark so exquisite, and it is almost impossible for one person or a few people to do it. In fact, even in the country, there are few such technical strengths. It is more difficult to reproduce the ink of special colors, and it is much more difficult than developing it. Coupled with the unique fluorescent anti-counterfeiting technology, it should not be possible to appear for a long time to be able to fake the real fake. Money. Of course, I'm not saying that counterfeiting is completely impossible, but I'm sure that the cost of counterfeiting it is even much more than its face value. In the Wall Street Journal, Mr. Mahler, an expert in anti-counterfeiting technology at Yale University, gave such a high evaluation.

As a result, ordinary people who lacked confidence in other gold dollar bills began to exchange these gold dollar bills for gold dollar bills issued by the Federal Reserve, and other gold dollar bills began to gradually disappear from the market...... R1058
