There was no fingerprint identification technology in ancient times, so why do we have to press fingerprints when drawing lots?
There was no fingerprint identification technology in ancient times, but people pressed their fingerprints because there were specially trained fingerprint identification professionals in ancient times, but their identification accuracy was far behind modern technology. In fact, the ancients did not have no fingerprint identification method at all, but their method was not very scientific and had certain limitations. The method used by the ancients was to divide fingerprints into? Snail? And then what? Basket? Two kinds? Snail? This is a vortex fingerprint, and its shape is spiral. Basket? It's a flowing fingerprint. The ancients got the answer according to the different principles of each person's fingerprint nodes and then compared them. Fingerprinting is not just a disguise. In ancient times, people discovered the uniqueness of fingerprints very early, so the process of fingerprint pressing was gradually handed down.

Of course, although the ancients could not compare fingerprints with high technology as we do now. But they still have a way. At that time, they mainly relied on human eyes to identify. Although the accuracy of this comparison result is not very high, it can basically meet the daily recognition accuracy. Now we open our hands and look at the fingerprints on our fingers with the naked eye. The difference between fingerprints is also easy to distinguish. Therefore, as far as the difficulty of naked eye fingerprint identification is concerned, this is not a sophisticated technology. In ancient times, there were many trained professionals specializing in fingerprint identification.

In addition to comparing fingerprints with the naked eye, we should know that fingerprints and signatures often exist at the same time. Not only fingerprints need to be compared, but signature comparison is also an extremely important procedure. In ancient times, few people could receive cultural education. In this case, the illiteracy rate is very high. Even many people can't write their own names, so it's not realistic to sign on paper. But there are countermeasures for everything. If they can't write their own names, they will be asked to make certain marks on the paper to confirm that they really know the words on the paper. It can be seen that writing on paper is an important method to replace not signing.

Existence is right, what's more, it has existed for thousands of years, and it has its advantages and scientific nature that paper painting can always be widely used by people.
