At the fingertips of each of us there is a certain pattern, unique and inimitable. It is also called the second "face" of a person. Throughout life, fingerprints remain the same, while other lines on the palms are constantly changing. They are believed to be needed to help hold objects and to improve the sense of touch.
Imprint instead of signature
Back in the 14th century, the Chinese used a fingerprint instead of a personal signature on documents. In the middle of the 19th century, the English official William Herschel, who worked in India, drew attention to the fact that Chinese merchants who came with their goods, when concluding transactions, put on the contract an imprint of a thumb of their right hand blackened with ink or soot. And since 1858, Herschel began to take fingerprints from Indian soldiers, to whom he paid salaries.
The method of identifying a person by fingerprints is called fingerprinting. The most important area of its application has become forensic science. On April 18, 1902, fingerprints were used in Denmark to identify a criminal, and already in September of the same year in Great Britain fingerprints from a crime scene were first used as evidence of guilt in relation to a suspect in a crime.
