Citizen identity, benefits and to ensure universality – The ID can be used to identify the individual in any part of the country, so even if a person travels, this card will be sufficient to establish or verify his identity. Also, there are various citizen benefits that can be availed with this card.
Corruption - Aadhar card is expected to reduce corruption. Sonia Gandhi emphasized that with the introduction of Aadhaar issues such as corruption and fake ration card can now be dealt stringently. Gandhi added the card will further help in minimizing the corruption in PDS (Public Distribution System).
Empower weaker sections – The poor did not have any identity proofs and so was prevented from availing services such as bank accounts, ration cards etc. In a function organized in Nandurbar district of Maharashtra where Aadhaar ID cards were first distributed to villagers, Prime Minister Manmohan Singh pointed out that the poor could not avail the benefits of government welfare programs because of lack of identity proofs and many times those benefits were pocketed by others.
Online government or e-governance – Aadhar card is expected to facilitate digital interaction between a government and citizens (G2C), government and businesses (G2B), and between government agencies (G2G).
