India paid fertilizer subsidy only on thumbprint-verified retail sales

Fertilizer was India's second-biggest subsidy after food — around Rs 70,000 crore budgeted for 2017-18 — and it leaked the old-fashioned way: subsidised urea was diverted to non-farm uses or smuggled across borders to be resold at market price, while farmers occasionally faced shortages and overcharging. The LPG solution of crediting cash to buyers' bank accounts did not transplant directly, because imported fertilizers like potash are costly and small farmers could not front the full market price.

So the Department of Fertilizers, through a NITI Aayog committee, re-engineered the flow instead of the payment: keep the counter price subsidised, but make reimbursement conditional on a verified sale. After a 16-district pilot, PoS devices went to retailers nationwide for an August 2017 rollout; each sale records the farmer's Aadhaar-authenticated identity, the retailer, the product, the plot and stock, and the manufacturer is repaid within days on that record. By early 2018 the system covered 19 states and union territories.

An independent evaluation agency appointed by NITI Aayog surveyed 5,659 farmers and 427 retailers across 14 districts: the Aadhaar authentication strike rate reached 97% within three attempts, 85% of farmers received transaction receipts, 98% were charged exactly what the receipt said, and 79% of retailers were satisfied. Farmers gained transparency at the counter; the diversion margin, which had lived in the gap between shipped bags and verified sales, lost its cover.

Pay the subsidy on the verified sale, not the shipped bag

Subsidising the verified transaction rather than the shipped product closes the accounting gap in which diversion used to hide.

Keeping the counter price subsidised protects small farmers from the upfront-cost problem that a straight cash transfer of expensive fertilizer would create.

Authentication at the point of sale is cheap, offline-tolerant and already familiar from other Aadhaar services, so rural retailers could adopt it.

Daily reimbursement of manufacturers turned a slow, disputed claims process into a cash-flow benefit, buying industry buy-in for the compliance burden.

The digital trail (buyer, product, plot, stock) gives the government soil-use and distribution data it never had, improving planning beyond fraud control.

When a subsidy leaks mid-chain, move the payout to the authenticated retail counter — diversion then generates a record instead of a margin, while the counter price stays affordable for the poor.

DBT in fertilizers went nationwide in 2018 and became the default subsidy pipeline for the sector, with the government later citing reduced diversion and faster manufacturer payments. Frictions remained — some dealers exited over thinner margins and less side-income, and rural connectivity required workarounds like external antennas and device-agnostic apps — but a majority of surveyed farmers and retailers said they preferred the new system to the paper one it replaced.
