UPI Abroad: Does It Work in Thailand/Vietnam?

Widespread retail UPI is not live yet for regular Indian banking apps in Thailand or Vietnam, so grab a zero-forex card and carry cash to avoid the flat 220 THB ($7.70) or ₹750 ($7.70) local ATM fee. While multilateral networks like Project Nexus are targeting operational frameworks in 2026, you cannot rely on scanning QR codes at local street vendors just yet.

The Cash vs. Card Strategy

Don’t land in Bangkok or Hanoi expecting to scan QR codes with your PhonePe or Google Pay everywhere. While everyone talks about UPI international expansions, the reality on the ground is that widespread retail merchant access for your regular Indian banking apps is limited in Thailand, and Vietnam’s integration won’t be fully operational until 2027.

Your actual strategy needs to be a 60/40 or 70/30 split between digital cards and physical cash. Use your zero forex markup cards for your heavy hitters—like booking rides on the Grab app, paying at mid-to-high-end restaurants, or settling hostel bills. Cash is still king for your midnight Pad Thai, street market bargains, and local buses.

If you are heading into Cambodia and Laos, put the cards away for daily spends. Physical cash is entirely mandatory there. Carry clean, high-denomination $50 or $100 USD bills printed after 2013 to exchange locally because keeping everything in cards will leave you stranded at local shops.

Zero Forex Markup Cards vs. Traditional Forex Cards

Stop using traditional prepaid forex cards loaded with USD for a multi-country trip. If you load a standard card with USD and swipe it in Bangkok or Ho Chi Minh City, the bank hits you with a hidden cross-currency markup fee that often reaches 3.5% plus 18% GST every single time it converts your USD balance into Thai Baht or Vietnamese Dong.

Instead, grab a zero forex markup debit or credit card before your flight. Cards like the DCB Niyo Global Visa Platinum Debit Card link directly to an INR savings account, charge zero joining fees, and use real-time live Visa rates with 0% foreign currency markup on point-of-sale payments.

For credit cards, options like the Scapia Federal Bank Credit Card or the AU Ixigo Credit Card offer true 0% forex markup on international transactions. Scapia has zero joining or annual fees and throws in lounge perks based on your travel spends, though cash advances will hit you with a flat 2.5% or ₹550 (~$6.00) fee. AU Ixigo works the same way but adds booking discounts on international hotels and flights. These cards convert directly from base INR to the local currency on the spot network rate, saving you thousands.

ATM Fees & Withdrawal Rules

ATMs in Southeast Asia are a racket, and you need to know the rules to avoid bleeding money. Every single time you slide your foreign card into a Thai ATM, you get hit with a steep, non-negotiable flat operator fee of 220 THB ($7.70), which is roughly ₹750 ($7.70) INR, completely separate from whatever your Indian bank charges.

In Vietnam, the fee ranges from 22,000 to 55,000 VND ($0.86 to $2.16), which translates to ₹90–₹220 ($0.93–$2.34), with TPBank charging a variable fee of around 50,000 to 165,000 VND ($1.96 to $6.47). Cambodia charges a flat $4 to $6 USD ($4.00 to $6.00), which is about ₹380–₹550 ($4.00–$6.00) INR. Laos hits you with 20,000 to 40,000 LAK (~$0.96 to $1.92), roughly ₹90–₹180 ($0.96–$1.92) INR.

The math to survive this is simple: withdraw the maximum amount allowed per transaction to dilute that flat fee. In Thailand, banks like Krungsri or Bangkok Bank allow high limits of 20,000 to 30,000 THB per run. In Vietnam, most networks cap you at a low 2,000,000 to 5,000,000 VND, but VPBank is the absolute favorite for travelers because it charges zero local ATM access fees for foreign cards and allows a massive limit of up to 10,000,000 VND per transaction. In Cambodia, aim for $500 to $1,000 USD per run, and in Laos, use BCEL Bank (the blue ATMs) for the most competitive standard flat fees of 20,000–30,000 LAK, since their transaction limits are low at 1,500,000 to 2,500,000 LAK.

RBI LRS & TCS Tax Rules for Indian Travellers

Let’s talk about taxes because the Indian government tracks every rupee you spend abroad under the Liberalised Remittance Scheme (LRS), which caps your total foreign spending at USD 250,000 per financial year. Following the recent policy updates, the standard threshold sits at ₹1143000 (~$12,000) per financial year across your independent forex loads and debit card swipes.

If you spend under ₹1143000 ($12,000) inside an FY on independent travel outlays like loading a forex card or using your international debit card, you pay 0% TCS. The second your aggregate international spending hits ₹11,43,000a flat 20% TCS applies to every amount exceeding that ₹10($12,000) mark.

However, if you buy an overseas tour package via an operator, the rules are different: you get hit with a flat 2% TCS from the very first Rupee, with no minimum threshold at all. The good news? Physical international credit card swipes while you are physically traveling abroad remain completely excluded from the LRS framework for now and do not attract TCS upfront.

If you’re travelling with Bananarchy, your overland transport and hostels are paid in INR before you leave India — so you stay well under LRS limits and avoid TCS hassles.

Where to Exchange Cash locally

If you want physical cash, never convert INR directly into local currencies on arrival because airport margins are absolutely terrible. Instead, buy a small starter amount of 3,000 to 5,000 Thai Baht (~$100 to $170), which is roughly ₹10,000–₹17,000 ($107–$180) INR, while you are still in India. For the rest of your cash needs, carry crisp, uncreased, high-denomination $50 or $100 USD bills printed after 2013.

In Thailand, skip the exchange booths at the main terminal arrival gates. Walk straight down to the B-Floor near the Airport Rail Link at Suvarnabhumi Airport and look for SuperRich (either the orange or green booths), or head to their central Bangkok hubs like Siam Paragon and Rajdamri for the tightest market rates.

In Vietnam, do not look for standard banks to change your cash. Head to the local gold shops in Hanoi’s Old Quarter, specifically along Ha Trung Street. If you are in Ho Chi Minh City, look for the gold shops right outside Ben Thanh Market to get the best conversion rates for your USD bills.

Actual Ground Costs for Budget Planning

To give you an honest picture of what your daily budget should look like, here is a clean breakdown of real costs across the region:

Item	₹ Cost	~USD
Thailand Hostel Dorm / night	₹270–₹470	~$2.80–$4.90
Vietnam Hostel Dorm / night	₹160–₹330	~$1.70–$3.50
Thailand Private Room / night	₹500–₹1000	~$5.30–$10.50
Vietnam Private Room / night	₹400–₹850	~$4.20–$8.80
Thailand Street Food Meal (Pad Thai / Boat Noodles)	₹50–₹130	~$0.54–$1.40
Vietnam Street Food Meal (Banh Mi / Pho)	₹30–₹100	~$0.36–$1.05
Laos / Cambodia Dorm Bed / night	₹160–₹400	~$1.70–$4.20
10–14 Days Tourist SIM Card	₹900–₹1,400	~$9.60–$14.40

Common Mistakes Indians Make

The most painful mistake is falling for the Dynamic Currency Conversion (DCC) trap at foreign POS terminals or ATMs. When you swipe your card, the machine will ask whether you want to be billed in Indian Rupees (INR) or the local currency (THB or VND). Always select the local currency; if you select INR, the overseas merchant’s bank handles the conversion and slaps an arbitrary premium of 3% to 10% over the standard market rate.

Another classic blunder is flying out with an unlinked or inoperative PAN card. Under current Indian tax guidelines, if your PAN is not linked with your permanent ID card, your bank is legally forced to charge punitively higher penal TCS rates on any international remittance or prepaid forex card loads.

Finally, traditional Indian credit cards will kill your budget if used mindlessly. Standard credit cards carry a heavy foreign currency markup fee of 2.5% to 3.5% plus an additional 18% GST on that markup value for every single transaction, meaning you are essentially throwing money away on everyday expenses.

What Most Guides Don’t Tell You

Most travel blogs won’t warn you about the strict physical condition rules for cash in Vietnam, Cambodia, and Laos. If your USD bills have even a tiny tear, ink mark, or a deep fold line, local gold shops and exchange counters will flat-out reject them or offer you a significantly lower rate.

Also, keep in mind that Cambodia runs a dual-currency system where the US Dollar handles everything major, but the Cambodian Riel (KHR) is used for change, fixed locally at 1 USD = 4,000 KHR. If you pay with a $20 bill for a $2 item, you will get your change back entirely in Riel notes, so do not carry massive USD bills for tiny street purchases.

FAQ

UPI Abroad: Does It Work in Thailand/Vietnam?

In Thailand, cross-border UPI integration with PromptPay is advancing via the BIS Project Nexus roadmap targeting full operational connectivity, though widespread retail merchant access for regular Indian banking apps remains limited. In Vietnam, a pilot digital connectivity corridor between India’s UPI and Vietnam’s NAPAS network has been proposed with a targeted operational rollout scheduled for 2027, meaning travelers cannot currently use native Indian UPI apps at local Vietnamese vendors.

What is the TCS rate on international travel from India?

Effective April 1, 2026, booking an overseas tour package via an operator incurs a flat, uniform 2% TCS from the first Rupee with no minimum threshold. For independent travel outlays (such as loading a forex card or debit transactions), a 0% TCS applies up to ₹1143000 ($12,000) per financial year, jumping to 20% TCS on any aggregate spending above the ₹1143000 ($12,000) mark.

Are Indian credit cards accepted in Thailand and Vietnam?

Yes, Visa and Mastercard credit cards issued by Indian banks are widely accepted at major hotels, mid-to-high-end restaurants, and ride-hailing apps like Grab across Thailand and Vietnam. However, traditional credit cards carry a heavy foreign currency markup fee of 2.5% to 3.5% plus 18% GST on the exchange value per transaction.

How much cash should I carry to Thailand or Vietnam?

Travelers should carry roughly 3,000 to 5,000 Thai Baht (~$100 to $170), which is about ₹10,000 to ₹17,000 ($107 to $180) INR, or $300 to $500 USD in physical cash to cover baseline emergencies, street food stalls, and transport hubs. The bulk of your budget (50%–60%) should sit safely on a digital zero-forex card to avoid high physical exchange markups.

What is the best zero forex markup card in India?

The DCB Niyo Global Debit Card and Scapia Federal Bank Credit Card are the top choices because they offer true 0% foreign transaction markups, mapping transactions directly to live wholesale network (Visa/Mastercard) mid-market rates without hidden commissions.
