Unique Identification Number for Indian Residents (Unique ID)

I believe that it is a challenge to every one to think of ways in which Indian residents could get more out of unique IDs to be issued than what the US Social Security number gives US residents. I am not referring here to Social Security payments, which would require a lot of policy-making and financial calculation.

What I refer to is this: Coming at a time the Internet and e-Commerce are so well developed, does the concept of a Unique ID offer new opportunities in cyberspace?

Let your imagination loose!
