Supreme Court on Monday asked Centre to put in place an effective mechanism to verify identities of existing mobile users within a year.
A bench comprising Chief Justice J S Khehar and Justice N V Ramana said the verification of existing pre-paid mobile users, running into cores, be done within one year.
The bench was hearing a plea filed by NGO Lokniti Foundation on the issue.
Since more people have now started using mobile phones making digital payments and other banking purposes, it becomes pertinent to keep a track of all and so that SIM cards are not being used.
Attorney General Mukul Rohatgi also cleared the air on verification process as it would apply to both existing and fresh subscribers.
He also told the court that 90 per cent of the mobile connection holders have pre-paid connection.
