Fingerprint identifies are necessary to control immigration and prevent criminals from illegalentry into the ground.

Scientists from the University of California are developing a technique of identifying fingerprints based on the chemical rest that has left the fingers of man. If the prints are on the object, the fingerprints can be seen in the color using a light similar to the light used in the X -ray machine.
