India is going to find out that iris scanning suffers from all of the same issues as any other biometric scanning device. ALL of them have to turn the scan into a digital representation, which is then used to authenticate or verify identity. The weak point int he process is between the device and the computer. Since that digital representation can be copied and replicated, it is no more secure than any other identification system. It's actually less secure, because it's considered the user name AND password. Any biometric system really needs a second factor, a password, to go with it.
