The QR code taped to a million Indian shop counters is starting to appear abroad. The Unified Payments Interface, which processes more monthly transactions than the world’s largest card networks, has been linking with payment systems in Europe, the Gulf, Southeast Asia and beyond, letting travellers pay from their Indian bank accounts in rupees at foreign tills.
For the Indian traveller, the appeal is obvious: no forex card, no cash conversion queue, no three-per-cent markup surprises. For partner countries, the appeal is the tourist volume itself — Indian outbound travel is among the fastest-growing in the world, and merchants want to be payable in the way those customers already trust.
Why the model travels well
UPI’s design choices made export easier: it is interoperable by mandate, settles instantly, and costs merchants a fraction of card fees. The National Payments Corporation of India has spun up a dedicated international arm to negotiate linkages corridor by corridor, each requiring regulatory alignment on limits, dispute handling and data rules. Our fintech coverage has mapped the growing list of live corridors.
Remittances are the larger prize. India receives more money from its diaspora than any other country, and instant low-cost rails could compress fees that still average several per cent on some routes.
The hurdles are diplomatic, not technical
Each linkage is a negotiation between central banks with different fraud rules, consumer protections and data-localisation instincts. Transaction limits abroad remain modest, and acceptance is concentrated in tourist districts rather than everywhere a traveller might wander.
Merchants at the other end
For the shopkeeper in Dubai, Paris or Singapore, accepting UPI is a calculation about who walks past the till. Indian tourists rank among the world’s highest-spending travellers in several destination markets, and payment friction is a silent sales killer: every declined card or cash-only sign converts footfall into someone else’s revenue. Acquirers have responded by bundling UPI acceptance into the same QR infrastructure Asian merchants already use for regional wallets, so the marginal cost of saying yes keeps falling.
The corridors also run in reverse for the diaspora: visitors to India increasingly pay with foreign instruments linked into the same rails. Each direction that works makes the network more valuable to the next country deciding whether to connect — the classic logic of payment systems, finally operating in India’s favour.
For policymakers watching from other emerging markets, the export is the template as much as the technology: build an open, interoperable rail at home, drive adoption to ubiquity, then negotiate linkages from strength. Several countries are now explicitly modelling their instant-payment systems on the architecture, with Indian engineers and firms consulting. Payment rails, once as unglamorous as plumbing, have become an instrument of soft power — and India is discovering it manufactures them rather well.
Still, the direction is historic. Payments infrastructure was once imported into India; now India exports it, and the humble QR at the paan shop has become an unlikely piece of economic diplomacy.
