BMC chief has commented that the number will be issued to everyone irrespective of his/her nationality, which means all Bangladeshis residing in India will also be given the unique identification number.
This seems very strait forward; let’s hope it is! 🙂 The reason being UIDAI has never claimed of being card/proof identity or any kind of proof of being Indian national; it has recently mentioned that it’s sole purpose is to provide unique indenty every person in this country. These are steps of caushin taken by UIDAI, of course Mr. Nilekani has learned lessons from some countries doing such projects.
The number will not be a secret number as SSN in U.S. or SSIN in Canada, rather it will be more like your PAN used for Indian Income-Tax purposes, which can be shown to everybody without any fear of being misused.
