Nowadays, with the development of science and technology, people's lives have been greatly facilitated. For example, today's fast payment allows us to go out without wallets and bank cards. Anyway, you only need to bring a mobile phone, which is the most convenient way to pay the fingerprint identification fee.
In fact, there are also such scenes in costume dramas. It is those who commit crimes that not only need to sign the guarantee, but also need to press the last fingerprint. Having said that, you may think that in ancient times, in a society with poor materials and underdeveloped technology, there was no fingerprint recognition. Then, why are those who interrogate the confessor still signing and fingerprinting? ?
You know, in ancient times, some important activities required signatures. But perhaps because of the limited education level at that time, many ordinary people just worked for a living, so there were not many people who could really study. At this point, most signatures are replaced by symbols. But later, it was found that a piece of paper was full of messy symbols, and it was impossible to identify who wrote it. Later, in order to identify, I came up with such a method. After signing, I pressed my fingerprint.
Because, at that time, the wise ancients found that everyone's fingerprints were different. It is understood that as early as the Zhou Dynasty, some people associated wealth with people's palms. So this may also be the reason why the ancients associated signatures with fingerprints for identification.
Another reason is that ancient people's thoughts are more traditional. So, when you sign your name and press your fingerprint, you will be under the supervision of God. You naturally dare not violate it in any way.
