Biometrics is the modern method for physical identification.
This term have been used since early in the 20th century for the analysis of data from agricultural field experiments to compare the yield of different varieties of wheat.
Recently the term biometrics has also been used to refer to the emerging field of technology devoted to identification of individuals using biological traits.

Finger print scanning
Finger prints are the bizarre twists of nature, which represents you alone,literally at your finger

How it works ?
The user presses his finger gently against a small reader surface (optical or silicon) usually about 2 inch square size.That reader is attached to computer to the information within, and that information is compared to database already stored.

How the scanner works ?

The human fingerprint is made up of ridges that take the shape of loops,arches, and whorls.
Two types of scanner are used
Optical reader (inexpensive and durable)
silicon reader (higher quality)
In silicon chip based scanners a chip measures skin capacitance to discover the ridge pattern in the finger print

How identification and verification happens It consists three stages
data acquisition or sensing of finger print
template from sensed image
decision making
Implementation of fingerprint scanning takes three steps

Image capture
signature extraction

It was first used in 14th century in china to distinguish their children from others, they used their feet stamped in ink.
In 1858, Sir William Hershel chief magistrate used to identify the dishonesty of local natives.
Major use
Finger print scanning secure entry devices for building door locks.Recently a small number banks have begun finger print reader for authorization in ATMs and grocery stores.
Market size
Finger print scanning technology is expected to grow from $66 million in 1999 to $991.3 million in 2004.
