> From anti-corruption point of view, this is really going to be helpful. Any government aid etc can be tracked using the UID (i.e. to see who the beneficiary was). Currently a majority of such funds are eaten up by the politicians and bureaucrats. So perhaps that will get reduced.

"perhaps"? That's your plan? Hope is not a plan.

Unless Indian pols,grifters, and the like are significantly less competent than American ones, an ID card won't have any effect on corruption, waste of govt aid, and so on.
