Ancient fingerprint recognition technology was actually very advanced

Our ancestors discovered early on that everyone's fingerprints are unique. In addition to using the dustpan pattern and bucket pattern to classify fingerprints, they also use the sparseness and density of the patterns to determine the age of the fingerprint owner - the fingerprints of adults are denser than those of teenagers.

Therefore, fingerprints became an important form of identity proof for the ancients. To identify the owner of a fingerprint, one only needed to ask the "owner" to press the fingerprint again and then compare it with the existing fingerprint under the sun. If the two fingerprints completely overlapped, the identity of the "owner" could be proved.

During the Song Dynasty, the government even collected fingerprints from the people. It was simply the "first generation fingerprint database"!

Today's fingerprint recognition technology is more advanced and has more widespread applications, but to some extent, it is a continuation of ancient fingerprint recognition technology!
