With the development of science and technology, more and more people don't need to bring their wallets when they go out. There are mobile phones all over the world. When paying, they just need to "touch" the mobile phone with their fingers and then complete the payment "drop by drop". Unlocking fingerprints has long been a part of daily life.
Friends who have watched ancient TV dramas know that the government will write a confession in advance after catching the prisoner. Once the prisoner confesses, they will immediately press their fingerprints according to his paintings, which is called "hand in hand". Modern police can use fingerprint system to find criminals, but why insist on "holding hands" in ancient times when technology is backward? What if a customer cheats after fingerprint identification? Don't be afraid, we ancient people in China have great wisdom!
The first reason is that China studied fingerprints in ancient times. As we all know, people's fingerprints are different, and the repetition rate is very small, about11.500 million, so it is called "people's ID card".
As early as 3000 years ago in the Western Zhou Dynasty, people in ancient China found that people's fingerprints were different. However, it was not used as some kind of evidence at first, but used to "look at the picture". In the early years of the Western Han Dynasty, a woman named Xu Yin also published two books, listening to the sound, motion and the five beasts, and teaching people to look at pictures. When Liu Bang, the Emperor Gaozu of Han Dynasty, called her "Ming Fei", she was one of the few female governors in ancient times, which shows her lofty status.
In the Qin dynasty, fingerprints were used to judge cases. Fingerprint identification technology began to mature in the Tang Dynasty. A large number of documents, contracts and wills unearthed in the Tang Dynasty all have fingerprints or palm prints. 1927, German Robert Haindl wrote in his book Fingerprint Identification that Jia of Tang Dynasty in China was the first person in the world to identify people with fingerprints.
Everyone is familiar with the "unjust, false and wrong cases" in the Song Dynasty. Song Ci is known as "the originator of forensic medicine in the world". He founded Forensic Medicine on 1235. There are many cases based on fingerprint collection.
In addition, there is a book called unjust, false and wrong cases in ancient China, which records the name, age and home address. The details of the soldiers and everyone's fingerprints were recorded! During the Southern Song Dynasty, not only soldiers but also ordinary people began to register, and an ancient "fingerprint database" was established, and specialized institutions managed and studied fingerprints.
So once someone committed a crime in ancient times, the government printed his fingerprints and sent them to various regions. By comparing the fingerprints on SkipBook, we can lock the criminal. This is really an eye-opener!
The second reason is the ancient people's respect for God. The ancients said, "God is three feet ahead." Once you sign the confession, you will be punished by God. If anyone dares to hide or lie, God will see it, so they dare not easily deny their signatures and fingerprints.
The third reason is simple, to prevent criminals from not writing. After all, there were not many people who could not read and write in ancient times. If they meet someone who can't write, it's convenient to press their fingerprints.
Today, the method of "fingerprint identification" is still recognized. For example, the Capital Plan stipulates: "If the parties conclude a contract in the form of a contract, they shall sign or seal it. If the parties sign the contract, the people's court shall determine that it has the same legal effect as the signature or seal. "
For more than two thousand years, China's fingerprint identification technology has been ahead of the world. We really admire the wisdom of our ancestors!
