Maharashtra Government will put in place a biometric-based authentication system in the next four months to weed out bogus ration card holders and curb leakages of food grains, the Legislative Council was informed on Wednesday.

The biometric system will save about 30 per cent of the food grains under PDS currently going to undeserving and bogus ration card holders, Food and Civic Supplies Minister Girish Bapat told the House.
