You need a zero forex markup card like Fi paired with 15-20% cash in local currency for street stalls. ATMs in Thailand hit you with a flat 220 THB (~$6.80) fee per withdrawal, so always pull out the maximum allowed limit to keep your costs down.

The Cash vs. Card Strategy
Look, I have done this exact Southeast Asian loop more than 30 times, and the absolute worst thing you can do is land with an empty wallet or a traditional bank card that bleeds you dry. The reality on the ground across Thailand, Vietnam, Cambodia, and Laos is totally split.
For Thailand and Vietnam, deploying a hybrid strategy is the smartest way to stop losing money compared to exchanging INR directly. You want a zero-markup debit card for swipes, online booking portals, and ride-sharing apps like Grab, paired with highly targeted local ATM withdrawals for physical cash.
Standard bank debit or credit cards will slap you with heavy cross-currency markup rates on every transaction, which is just throwing money away. Traditional forex cards are an outdated nightmare because you have to lock in your funds and load specific currencies, and they rarely support a clean multi-currency setup for a backpacking route.
When it comes to cash-heavy economies like Cambodia and Laos, Indian cards do not natively store local currencies. For these two spots, carrying physical, crisp, unblemished, new-series USD ($50 or $100 bills) from India is the right call for manual exchange. Cambodia runs on a dual-currency framework using both Cambodian Riel (KHR) and the US Dollar (USD), so having clean greenbacks is pure gold.
Zero Forex Markup Cards vs. Traditional Forex Cards
If you are still using old-school bank forex cards or standard debit cards, you are letting the banks fund their annual parties with your money. A standard bank card charges a 3.5% international cross-currency markup fee on every single swipe, meal, or hostel booking.
Zero-markup cards like the Fi Money Visa debit card (partnered with Federal Bank) completely change this game by offering zero foreign transaction markups natively. This means when you buy a coffee or pay for a hostel, the exact interbank exchange rate is applied without a hidden fee layer.
But here is where you need to look at the fine print on fi card international usage. Do not fall into the Plan Tier Trap. Indian backpackers frequently open basic, zero-balance Fi accounts right before traveling and incorrectly assume they automatically get zero-markup spending.
The rules say that “Standard” and “Regular” plans carry that high 3.5% international markup. You must maintain the target account minimum balances required for the Plus (₹25,000), Infinite (₹50,000), or Prime (₹1,00,000) tiers to get the waiver. Note that the Plus tier caps your global zero-markup transactions up to ₹30,000 per month, while Infinite and Prime give you full freedom.
ATM Fees & Withdrawal Rules
Listen to me carefully: zero forex markup does not mean zero ATM fees. No card from India can stop a local foreign bank from charging you to use their physical machine.
Here is the exact damage across the network:
- Thailand: A mandatory flat fee of 220 THB (~$6.80) per withdrawal applies across nearly all commercial operators.
- Vietnam: Surcharges vary significantly, ranging from 0 to 55,000 VND (~$0 to ~$2.20) depending on the bank.
- Cambodia: Standard local operator surcharges range between $4 USD to $6 USD (~$4.00 to ~$6.00) per transaction.
- Laos: A typical transaction network fee ranges between 20,000 to 30,000 LAK (~$0.80 to ~$1.25).
The mathematical play to survive this is simple: withdraw the maximum amount allowed per transaction to dilute that flat fee. Do not pull out small amounts.
To make your life easy, look for these specific low-fee banks on your route:
| Country | Best Bank to Use | Max Withdrawal Limit | Local ATM Fee |
|---|---|---|---|
| Thailand | Krungsri Bank (Yellow ATMs) | 30,000 THB | 220 THB (~$6.80) |
| Vietnam | VPBank / TPBank | 10,000,000 VND | 0 VND |
| Cambodia | Vattanac Bank | $500 USD | |
| Laos | BCEL | 1,500,000 to 2,500,000 LAK | 30,000 LAK (~$1.25) |
Krungsri allows the highest threshold in Thailand, minimizing the sting of the 220 THB surcharge ratio. In Vietnam, VPBank and TPBank stand out as the primary targets for budget travelers, offering completely free international ATM access (0 VND local fees) and a massive 10,000,000 VND single-withdrawal ceiling. Always hunt down these specific machines.
RBI LRS & TCS Tax Rules for Indian Travellers
Before you fly, you need to understand the legal guardrails set by the Reserve Bank of India. Under the Liberalised Remittance Scheme (LRS) framework, you get a cumulative ceiling of up to USD 250,000 per financial year across all foreign transactions. You are not going to hit that limit on a backpacking budget, but the Tax Collected at Source (TCS) rules will hit you if you are not careful.
Under the rules, self-funded international spends and foreign currency loads attract a 0% TCS rate for aggregate thresholds up to ₹10 Lakh per financial year across your cards. The moment you cross that ₹10 Lakh line, a heavy 20% TCS rate applies dynamically to any amount exceeding the limit. Keep in mind that separate rules dictate overseas tour packages, which command a 5% flat TCS rate from the very first rupee spent up to ₹7 Lakh, and 20% after that.
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 have physical cash that needs converting, stay away from the airport exchange kiosks. Their conversion rates are daylight robbery.
In Thailand, make your way to SuperRich booths. You can find them prominently at Suvarnabhumi Airport’s basement rail link station or around downtown Bangkok and Siam Square; they offer highly competitive conversion rates.
In Vietnam, skip the banks and airport booths entirely. Head straight to the local gold shops located within Hanoi’s Old Quarter (specifically Ha Trung street) or near Ben Thanh Market in Ho Chi Minh City. They consistently outperform any standard kiosk and will give you the cleanest rate for your foreign currency.
Actual Ground Costs for Budget Planning
To give you an honest baseline for your daily math, here are the actual on-the-ground cost estimates for budget travelers across these regions in 2026:
| Item | ₹ Cost | ~USD |
|---|---|---|
| Dorm bed / night | ₹480–₹1,300 | ~$5–$14 |
| Private room / night | ₹1,100–₹3,300 | ~$12–$35 |
| Street food meal | ₹100–₹380 | ~$1–$4 |
| Average Daily Basic Budget | ₹1,700–₹3,400 | ~$18–$36 |
Common Mistakes Indians Make
Accepting DCC (Dynamic Currency Conversion) at local ATMs or POS terminals. When a foreign terminal detects your Indian card, it will ask if you want to be billed in Indian Rupees (INR) instead of the local currency (THB, VND, etc.). It sounds convenient but it is a massive trap where the local bank applies its own terrible, inflated conversion rate. Always choose the local currency on the screen.
Exchanging Indian Rupees directly at local Southeast Asian booths. Trying to exchange INR physical notes in downtown Bangkok or Hanoi will break your budget; the rates are terrible because nobody wants INR there. Carry USD bills from India if you want manual exchange cash.
Assuming older travel advice from 2025 is still valid for card line-ups. Travelers reading older blog articles recommending the AmpliFi Federal Fi Credit Card for booking international flights and avoiding LRS limits should note that Fi officially terminated its AmpliFi credit card program and discontinued all existing card use on March 20, 2026. Stick to the verified account debit cards.
What Most Guides Don’t Tell You
The Reimbursement Delay Rule is a massive mental shock for first-timers using fi money abroad. Travelers are often alarmed when they notice immediate international charge penalties applied to their account balances after a swipe. Fi enforces a mechanism where a 3.5% markup is initially authorized and deducted on transactions, which is subsequently processed, verified, and reversed back to the eligible traveler’s account within 30 days. You need to keep extra buffer money in your account because that cash does not return instantly.
Physical card dependency is real. While India runs almost completely on virtual UPI and phone taps, contactless phone payments via Indian debit cards are highly unreliable at small local vendors in Vietnam or Laos. You must carry the physical debit card and ensure international usage, online transactions, and ATM access are manually toggled “ON” in your banking app before you clear immigration in India.
Is the Fi Money card good for international travel in Southeast Asia?
The Fi Money Visa debit card serves as a premier, highly secure choice for Southeast Asian travel, effectively enabling travelers on its Plus, Infinite, or Prime plans to execute zero forex markup spending across merchants and booking apps. However, users must realize that local physical ATM network access terminal surcharges (such as Thailand’s flat 220 THB penalty) remain fully active and are not absorbed by the card.
What is the TCS rate on international travel from India?
For individual foreign spends via debit or forex cards, there is a 0% TCS charge applied for cumulative values under ₹10 Lakh per financial year, rising to a 20% tax rate on any amount exceeding this threshold.
Are Indian credit cards accepted in Thailand?
Indian credit cards operating via global payment networks (Visa and Mastercard) enjoy near-universal acceptance rates in Thailand’s hotels, malls, and major commercial outlets, though they subject travelers to standard cross-currency markup rates.
How much cash should I carry to Vietnam?
While international cards are seamlessly integrated with booking systems like Grab, it is highly recommended to carry the equivalent of roughly $100 to $200 USD in physical cash to smoothly navigate local food markets, transport, and remote provinces.
What is the best zero forex markup card in India?
The Fi Money co-branded debit card represents a premier selection for modern digital banking due to its 0% forex markup guarantee across premium account tiers (Plus, Infinite, Prime).
