The state revenue increased multifold after illegal sand mining was kept in check in these two areas, Thorat said during the Question Hour.
The barcoded slips have all details of the drivers. Authorities issue a barcoded slip to the driver ferrying sand and track the vehicle from the loading spot to the delivery point. The system will be followed all over the state, especially in areas which report cases of illegal sand mining on a regular basis, he said.
Bar code receipts have invoice number that help track the driver better, he said.
