Amazing Biometric

Fingerprint ID has served mankind the past 100 years to provide accurate identification of people. No two fingerprints have ever been found alike in 6 billion humans.
Other visible human characteristics change - fingerprints do not.
The patterns of ridges on our finger pads are unique: no two individuals—even identical twins—have fingerprints that are exactly alike.
The first systematic use of fingerprints in the U.S. by the New York Civil Service Commission for testing began in 1902.



Like the fingerprints, each person also has a unique DNA.
Fingerprint can be altered by surgery, DNA fingerprint is the same for every cell, tissue, and organ of a person. It cannot be altered by any known treatment.



Do identical twins have identical DNA?
A DNA test can't determine the difference between identical twins, while a simple fingerprint can.
