Why?
Questions
? In the modern world, there is an ever
growing need to identify individuals. ?
Should this person be given access to a secure
system? ? Does this person have authorization
to perform a given transaction? ? Is this
person a citizen of our country? ? Every day,
questions like these which are related to
establishing the identity of individuals
are asked millions times.

Current System
Why?
? Person have to use more and more IDs ?
Possession (Key, Credit card, ) ? Knowledge
(password, PIN, )
