The plan to impose a fee on person-to-merchant UPI payments above a certain threshold risks undermining the very scheme this government promoted after demonetisation to usher the nation into a less-cash, more formal economy.Its real impact would fall on person-to-merchant payments, which account for two-thirds of the total value. It is naive to think that entities paying the charge would not find ways to recoup it.Any fallback towards cash transactions due to the extra cost would far exceed, directly and indirectly, the cost of sustaining the UPI. Official assurances notwithstanding, there are fears that once the legal architecture for the charge is established, its scope may be broadened in the future to comply with further US dictates.Kamal LaddhaBengaluruThe article ‘UPI is not a ‘cost’ to be recovered’, (August 11), raises a valid point. The large scale adoption of UPI payment has eaten into the profitability of entrenched card networks like Visa and Mastercard. That this does not go well with those networks is plain truth.The pious proclamations and promises of the government (that MDR will be for select transactions and small business will not be charged) aside, in the course of time the cost will be transferred to the public. In that way it disincentivises digital adoption and obscures transaction trail for ordinary small businesses.The argument that ‘someone must pay’ finds answer with the nation paying from the savings on printing/circulating currency. The expenditure supporting research, development, deployment of digital payments systems should be prioritised for legitimate CSR spends.Jose AbrahamKottayamStart-up successWith reference to ‘How a Mumbai start-up cracked missile cooling tech’, Mumbai’s Techno Defence has achieved what few nations can. It has developed an indigenous miniature Joule Thomson cryocooler for missile IR seekers. It has broken the western monopoly and proved that Indian start-ups can deliver strategic and high precision defence components. India should prioritise niche subsystems for exports, and partner early with DRDO. If we can successfully replicate this model it can move from platform assembly to becoming a trusted global supplier of mission critical defence technologies.Bal GovindNoidaPublished on August 11, 2026Sign into Unlock benefits!Access 10 free stories per monthAccess to comment on every storySign up/Manage to our newslettersGet notified by email for early preview to new features, discounts & offers${ ind + 1 } ${ device }Last active - ${ la }
