If you have ever stood at a Bangkok street food stall or a bustling Phuket night market, you know the frustration of fumbling for physical cash or dealing with unfavorable currency exchange kiosks. Thailand and India pull millions of travelers back and forth across their borders every year, yet travelers still rely on outdated cross-border payment methods. That might change if recent diplomatic pushes turn into technical reality.
Thailand’s Ambassador to India, Chavanart Thangsumphant, recently laid out a straightforward vision during the Federation of Hotel & Restaurant Associations of India convention. Her argument centers on a simple premise: bridging India's Unified Payments Interface (UPI) with Thailand's PromptPay network. It sounds obvious, but building this financial highway requires overcoming serious bureaucratic and technical hurdles.
The Reality of India and Thailand Travel Ties
You don't need a heavy macroeconomic report to see that tourism between these two countries is massive. Flight paths are packed. Over fifteen Indian cities offer direct flights to Thai hotspots, maintaining hundreds of weekly connections. In 2025 alone, millions of Indian travelers visited Thailand, making up one of the largest foreign tourist cohorts entering the country.
People aren't just booking standard vacations. High-end destination weddings from Indian families are booming across Thai resorts, largely because short flight times from places like Delhi make logistical planning far easier than flying to Western Europe. On the flip side, Thai travelers are increasingly heading to India for unique cultural, spiritual, and regional trips, exploring mountainous terrains like Ladakh.
Given this massive movement of people, the payment infrastructure feels archaic. Travelers still rely heavily on international credit cards laden with foreign transaction fees, pre-paid forex cards, or physical cash.
Why Connecting UPI and PromptPay Makes Sense
India has mastered instant digital transactions through UPI, handling billions of domestic payments every single month without breaking a sweat. Thailand runs a similarly mature domestic QR code ecosystem through PromptPay, which locals use for everything from paying taxi drivers to buying groceries.
Ambassador Thangsumphant pointed out the obvious friction: if an Indian tourist could open their usual banking app and scan a PromptPay QR code in Bangkok, or a Thai visitor could use their local app to pay for goods in an Indian market, spending habits would completely transform.
Right now, cross-border retail payments involve complex card networks or specialized regional wallet arrangements. Direct bank-to-bank QR interoperability cuts out unnecessary middlemen. Lower transaction fees mean more money stays in the pockets of travelers and local merchants alike. Small vendors in tourist-heavy regions benefit the most because they rarely want to deal with processing high-fee international credit cards.
Obstacles Standing in the Way
Talk of linking payment rails sounds great in a conference speech, but execution takes time. Central banks move slowly for good reasons. Security protocols, anti-money laundering regulations, and foreign exchange controls differ wildly between the Reserve Bank of India and the Bank of Thailand.
Settlement mechanisms also need careful design. When money moves instantly across borders, commercial banks and central institutions must settle the underlying currencies behind the scenes in real time. India has already successfully tested similar bilateral digital payment linkages with neighboring countries and select nations in Southeast Asia, proving the technical architecture is entirely possible. Extending that framework to Thailand is the next logical step, but it requires sustained political will and technical alignment.
What This Means for Your Next Trip
If you are planning a trip between these two destinations anytime soon, don't throw away your travel card just yet. Direct UPI-to-PromptPay integration for retail users isn't live today. You still need to rely on local currency, credit cards, or specialized multi-currency travel wallets when moving between Delhi and Bangkok.
However, watch this space closely. Both governments recognize that modern travelers expect financial apps to work across borders just as easily as messaging apps do. When these two networks finally connect, traveling between India and Thailand will get significantly cheaper and easier. Keep your passport ready and watch for updates from your banking provider regarding international QR compatibility.
