systems replacing PIN or cards.
 Process of fingerprint recognition
z Fingerprint consists of ridges and valleys. Ridge is a flow of protruding skin in a fingerprint while
valley is a hollow between two ridges. Each individual has different pattern of ridges and valleys
and finger recognition makes use of such originality and uniqueness of these patterns.

impossible to reconstruct a fingerprint image from a fingerprint template which is just numeric data
of the features of a fingerprint.
