One million Indian residents are expected to enroll for unique identity (Aadhaar) number every day from this October, Nandan M Nilekani,  Chairman, Unique Identification Authority of India, said on Thursday.

"As UIDAI scales up the systems both at the back-end by adding more technologies and at the front by adding more enrollment stations, it's confident of achieving this goal," he said.

Speaking at a conference with the theme "Next Generation Service Delivery - Enabled by Aadhaar", organised by NASSCOM and UIDAI in Bangalore, Nilakani said that as of now 95 lakh (9.5 million) people have been issued with Aadhaar numbers.  Another UIDAI official said the figure is expected to cross one crore on the same day.

Nilekani said plans are on track to issue Aadhaar numbers to 600 million (60 crore) people in three to three-and-half years. He said the entire enrollment infrastructure would stabilise in the next few months, adding, UIDAI has built a massive biometrics-based capabilities.

"We are very comfortable that in the next few months, we will have critical mass of people around the country who will have Aadhaar numbers with them," he said. He further stated that UIDAI would create for the first time in the country a national devices' infrastructure, which is inter-operable.

Nilekani said devices compliant with Aadhaar standards, -- whether they are in bank branches, or kirana stores or post offices or in schools or public health centres or anywhere -- would be inter-operable.

Nilekani later added that Karnataka and Andhra Pradesh had topped the list in the implementation of the Unique Identification Programme with Karnataka having 18.11 lakh people already registered in their system.

Speaking at another event in the city- at the 34th annual general meeting of the Bangalore Chambers of Commerce and Industry, Nilekani commended that the state government had thrown in its complete support to the programme behind it and was determined to cover 80 per cent of the population under the programme by March 2012. Karnataka had also shown the lead in the applications of the programme to other services, he said.

The former Infosys CEO said the UID programme would help in disbursing the benefits of welfare schemes to all apart from providing them an identification. Nilekani said the programme was challenging owing to its scale, reach and complexity, adding the cost per individual from registering and providing a UID card worked out to around Rs 100-125.

Speaking on the occasion, Karnataka Chief Minister B S Yeddyurappa said the state had been a torch bearer in e-governance initiatives including the UID programme. The state had contributed to national projects in a big way and was determined in implementation of the UID scheme, he said.
