The EC’s efforts to have a clean electoral roll with full enrolment often falters due to a variety of reasons. Relentless urbanisation and inter-and intra-city movements pose a challenge to having an updated and accurate electoral roll in urban areas. A study carried out in Bengaluru prior to the 2008 Assembly elections in Karnataka revealed that the year-on-year change varied from 6 to 8 per cent.
Having photos printed on the electoral rolls was a step towards making identification easier at the polling station. But even photo ID card is no answer to the problem of duplicate registrations. The photo ID card was designed to have a unique number but there was no way to prevent a second card from being issued to the same person if he/she did not voluntarily disclose information as there was no reliable reference point against which checking could be done. A matching of photos was the only option but it is enormously time-consuming and needs physical verification before coming to a final conclusion. It is here that Aadhaar provides a clean and easy solution.
