The Centre has told the Supreme Court that its "One Nation, One Ration Card" (ONORC) scheme makes the food security to the migrant beneficiaries "portable" to let them get it from any fair price shop of their choice anywhere in the country using their existing ration cards with biometric authentication.

Portability gives them the choice to lift the entitled foodgrains from any fair price shop , while at the same time enables the family back home to draw the remainder of the eligible ration, it said. As regards those not yet having the ration cards, it annexed affidavits of 28 states and Union Territories out of a total of 34 on the mechanism for helping out the unregistered beneficiaries either by registering them or supplying them the dry ration.

 Delhi is among the states that are yet to adopt the portability of the ration cards, other states being West Bengal, Assam and Chhattisgarh, it said in a 7-page written statement, adding that the onus on implementation of ONORC is on these states.

The written statement has been filed in the context of the Supreme Court's order on May 24 to speed up registration of the migrant workers. The Court had expressed its dismay at a "woefully slow" process of the registrations it ordered on July 31 last year in a suo moto case taken up by it on the problems and miseries of migrant labourers.
