Visnagar's old name came from a craft that sold face to face: a buyer walked into a lane of workshops, held the pot, argued the weight. The pump trade that grew beside it is no different. The farmer comes to the counter, and the counter writes his number down.

The India guide sets out the consent rules under the DPDP Act.
