why and how does our fingerprint works ?
Answers
Each one of us know, fingerprints are used identify the thief or culprit in our those TV telecasted detective shows. Question is, how this exactly works.
Fingerprints are small ridges and valley patterns at the tip of each finger. Fingerprints are developed in the womb. Two people have not been found with the same fingerprints - they are completely unique. With modern scientific sophisticated machinery and powerful computers it is possible to record and read and develop a pattern of finger prints and that is how it works.
Fingerprint is a form of biometrics, a science that uses people's physical characteristics, which they use to identify them. Fingerprints are ideal for this purpose because they are cheap to assemble and analyze, and they never change.
Fingerprints are even more unique than DNA. Although identical twins can share the same DNA - their fingerprints cannot be the same.
