Indian government has planned to issue unique identifications to all citizens starting from 2009 End. This will be another initiative towards e-governance from Indian Govt. It will a smart card and can be a replacement for existing ration cards, voter ID cards.
There will be a seperate agency (named as UID Authority of India) created for creating/maintaining the database.
Not sure, whether Govt will be able to implement it successfully or not. There are already plenty of e-governance projects biting the dust. Problem with Indian government system is that, they just do the planning and do not act on implementation proactively.
