Nandan Nilekani, the Chairman of Unique Identification Authority of India (UIDAI) has said that the authority is aiming to issue a total of 600 million Aadhaar cards by the year 2014, covering about half of the country's entire population.

The UIDAI has already issued the cards to more than 380 million Indians under the mammoth project to provide an identification number of every Indian. Nilekani has said that 600 million people in the country will get the unique identity number for their identity. He said the UID will be a national inter-operable mobile identity based on biometrics which can be used anywhere in the country. The UIDAI has tied up with 220 enrolment agencies in the country for the project.

Nilekani said that the project has used state of the art technology to provide a unique identification number to every resident of the country. "Today we have enrolled 380 million of the 1.2 billion people. Our daily processing is about a million people a day. "Our goal is to reach 400 million this year and 600 million by 2014," he said. He was delivering the Eighth Annual Richard H Sabot Lecture 'Technology to Leapfrog Development: The Aadhaar Experience.

Aadhaar could improve monitoring enrolment for the Right to Education Act, financial inclusion, the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA), facilitating employment search and others along with making below poverty line (BPL) census a part of the proposed Food Security Act.

There are some concerns regarding leakages and misidentification due to class division in rural areas. Some also raise concerns about handling of privacy and security along with possibilities of data theft and abuse.
