The unique identification authority of India (UIDAI) will soon set up the infrastrcuture for updating information on its database, according to chairman Nandan Nilekani.

Noting that the need to update details like address (in case of a change), name (after marriage) or even biometric data (in case of permanent injury to finger) may arise, Nilkani said that a policy is being drafted keeping such concerns in mind.

He also said that the authentication in UID may not always be biometric and the authority is exploring certain self service transactions through mobile and internet. In case of such transactions a PIN may be provided to the users.  He noted that the UID can also be used for verification in case of online open accounts like Facebook and Twitter.

Nilekani was speaking at a conference organised by national association of software and services companies (Nasscom) in Bangalore.
