but the problem  is that if we want to authenticate
people and be sure that he is who he says we have to
use a system that already has database and eith debit
card I dont think  it be possible and at the other hand
it is not easy for everybody to have an account in
Saman bank or other online  banks(currently none)
and if the system wants to be successful it has to
make it easy for people to use it.
