Chinese fingerprint products received by the French military

Mr. Arnoult has participated in the Vietnam War. He is a veteran of the French army who has really been beaten. He is deeply respected by the military. In addition, when he was young, he met and became a good friend with a Chinese national leader during his studies in France. In the 1980s, he was invited by the leaders of the country to work in Guangzhou for 15 years and made great contributions to Sino-French friendship. Due to his special status in the military, the French military specially entrusted him to choose the fingerprint device , fingerprint lock , and fingerprint access control machine used by the military. After a number of large European companies fingerprint products were investigated, due to the interest in China, he also specially invited Dr. Yu Xuan Eiffel company to negotiate.
After 15 days of opening the bid, 11 domestic fingerprint products were collected in Socomatel. All of these products were produced by well-known European companies. Eiffel was the only Asian company to respond. Each company has a detailed introduction to its products, and has carried out the registration and identification demonstration of real people's fingers. Turn to the Eiffel corporate presentation, Dr. Yu Xuan proposal, just the presentation are conducted under ideal circumstances, it can not prove anything. In actual use, there will be some dirt on the surface of the human finger and the fingerprint collector. It is recommended to test under the dirt condition. So, Mr. Arnoult returned to the office to take the red ink, applied to the surface of each product's fingerprint collector, and then asked each company to re-identify the demonstration. As a result, except for the company, the products are not recognized after the ink is applied! All the people on the scene showed a surprised look. Next, Dr. Yu Xuan also suggested using silicone fingerprints for registration and identification. Each company uses the silicone fingerprints provided by Dr. Yu Xuan to register and identify on its own products. It was found that, in addition to the Eiffel products , the use of silicone fingerprints on other products is exactly the same as that of real human fingers. This means that if you use fingerprints made of silicone instead of real people, these products can't identify true or false. The fingerprint of the person is easily copied. On the cup, on the handle of the door is the fingerprint of the person. The American film "National Wealth" has such a lens.
