Don’t buy an HDFC ForexPlus card for your backpacking trip through Thailand, Vietnam, Laos, or Cambodia. It is completely obsolete because it does not support local currencies like Thai Baht or Vietnamese Dong, forcing you into expensive cross-currency markup fees of 2% to 3.5% on every single transaction.

The Cash vs. Card Strategy
Look, you cannot survive on just a card in Southeast Asia, but you shouldn’t carry a massive bundle of cash either. The sweet spot is a 80-20 split: keep 80% of your funds on a zero-markup plastic card and carry about 20% in hard cash.
Cash is an absolute operational requirement here. You need actual paper money for street food stalls, local night markets, tuk-tuks, and the cash-only Visa on Arrival counters if you cross overland into Laos or Cambodia.
Traditional credit cards from India work fine at big hotels, upscale restaurants, and major shopping malls in Bangkok or Hanoi, but standard bank cards will quietly bleed you with a 1.5% to 3.5% markup fee plus GST on every swipe. Traditional multi-currency forex cards like HDFC ForexPlus make even less sense. They are built for Western hubs where you can load USD, EUR, or GBP directly. In Southeast Asia, they force a terrible double-conversion loop: your INR turns into USD when you load it, and then that USD turns into Thai Baht or Vietnamese Dong when you spend, hitting you with heavy fees.
Zero Forex Markup Cards vs. Traditional Forex Cards
This is where traditional options completely lose the plot. An honest HDFC ForexPlus card review highlights that the card hits you with a painful 2% to 3.5% cross-currency markup fee whenever you spend in a currency that isn’t loaded as a base on the card. Since you cannot load THB, VND, LAK, or KHR onto it, you pay that markup on every single meal, hostel bed, and souvenir. Plus, they still charge you application fees and reloading fees every time you add money.
In 2026, the smart play is switching to modern INR-denominated zero-markup debit or credit cards. Options like Niyo Global (partnered with DCB or Equitas bank), Scapia, and IDFC FIRST WoW credit cards are the top choices right now.
Instead of locking your money into a foreign currency beforehand, these cards let you keep your balance in liquid Indian Rupees. When you swipe or withdraw money abroad, the backend engine dynamically converts your INR into the local currency at the raw, live Visa or Mastercard interbank exchange rates with true 0% cross-currency markups. No application fees, no reload fees, and no hidden margins.
ATM Fees & Withdrawal Rules
ATMs out here are convenient, but they are commercial profit machines. Every single time you insert a foreign card into an ATM in Thailand, the local banking network charges a flat transaction fee of 220 THB (~$6.70 / ₹560). It does not matter if your Indian card offers free international withdrawals—this is a local structural fee collected by the Thai machine itself.
In Vietnam, the local ATM fee is lower but still annoying, ranging from 22,000 VND to 60,000 VND (~$0.85–$2.35 / ₹70–₹195) per transaction.
The machine caps are where things get tricky. In Thailand, ATMs have high limits, capping single transactions between 20,000 THB to 30,000 THB ($610–$915 / ₹51,000–₹76,500). Banks like Krungsri Bank (the bright yellow machines) and Bangkok Bank are your best bets because they maximize value by letting you pull out the full 30,000 THB limit at once. In Vietnam, most standard bank ATMs have highly restrictive operational caps, often cutting you off at just 2,000,000 VND to 5,000,000 VND ($78–$196 / ₹6,500–₹16,300) per withdrawal. To beat this, hunt down VPBank machines—they offer entirely zero-fee, free international ATM cash withdrawals for foreign cards.
The math is dead simple: never withdraw small amounts. Use a basic strategy to dilute the flat fee:
$$\text{Effective Fee %} = \left( \frac{\text{Flat ATM Fee}}{\text{Total Amount Withdrawn}} \right) \times 100$$
Always pull out the absolute maximum amount the machine allows per transaction. Pulling out 20,000 THB in one go turns that 220 THB fee into a minor blip, whereas pulling out 2,000 THB multiple times will destroy your budget.
RBI LRS & TCS Tax Rules for Indian Travellers
Let’s clear up the regulatory confusion. Under the RBI’s Liberalised Remittance Scheme (LRS), you are legally allowed a consolidated cap of ₹23806000 (~$250,000 crore) per financial year for international spending and foreign remittance. Unless you are buying a penthouse in Bangkok, you won’t breach this limit.
However, the Tax Collected at Source (TCS) rules under the unified Union Budget 2026 guidelines require strict attention. The exemption baseline is set at a consolidated ₹1143000 (~$12,000) per fiscal year, and the rules split cleanly based on how you buy things. For booking a pre-packaged international tour through an agent, a flat 2% TCS applies from the very first rupee, with zero minimum exemption threshold. For loading traditional forex cards or pulling cash on an Indian debit card, you pay 0% TCS under ₹10 lakh per fiscal year. The moment your aggregate international spending or loading crosses that ₹10 lakh milestone within the same financial year, a flat 20% TCS kicks in on the excess amount.
Keep in mind that any international cash withdrawal or payment made via an Indian debit card is immediately tracked under LRS guidelines and counts directly against your annual ₹10 lakh TCS threshold. International credit card spends, however, remain deferred from the LRS aggregate calculation for now.
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 to carry cash as a backup, do not buy Thai Baht or Vietnamese Dong in India. Indian forex desks will give you terrible, predatory rates for these currencies. Instead, buy clean, high-denomination, crisp US Dollar (USD) notes from India, carry them over, and exchange them locally in the city center.
When you land at Suvarnabhumi Airport (BKK) in Bangkok, avoid the main airport terminal exchange counters entirely. Their margins are awful. Instead, take the escalator down to the Airport Rail Link level and find the SuperRich (green or orange) kiosks or the Vasu Exchange booths. They consistently offer the best mid-market rates.
In Vietnam, skip the airport exchange windows entirely when landing in Hanoi or Ho Chi Minh City. For the absolute best rates in Hanoi, head straight to the Old Quarter. There is a cluster of trusted local gold shops on Hang Bac Street that trade currency all day at rates vastly superior to any commercial bank counter.
Actual Ground Costs for Budget Planning
To give you an idea of how much money you actually need to load or carry for a standard backpacking trip through Thailand or Vietnam, here is a breakdown of real, on-the-ground cost estimates for 2026:
| Item | ₹ Cost | ~USD |
|---|---|---|
| Dorm bed per night (Hostels like Lub d) | ₹550–₹1,350 | ~$6–$14 |
| Private room per night (Guesthouses / Boutique) | ₹1,350–₹3,300 | ~$14–$35 |
| Street food meal (e.g., Pho or Pad Thai) | ₹110–₹330 | ~$1.20–$3.50 |
| Tourist SIM card (10–14 days data plan) | ₹380–₹1000 | ~$4–$11 |
| Airport taxi to city center (BKK or HAN) | ₹1,100–₹1,400 | ~$12–$15 |
| Estimated daily budget (Backpacker style) | ₹2,100 – ₹3,800 | $25 – $45 |
Common Mistakes Indians Make
When you swipe your card or withdraw cash at a foreign terminal, the machine will often look at your Indian card and ask whether you want to settle the bill in Indian Rupees (INR) or the local currency (THB or VND). Many travelers select INR thinking it keeps things clear. This is a massive mistake. Choosing INR triggers Dynamic Currency Conversion, allowing the local merchant’s bank to apply their own predatory internal exchange rates, adding an instant 4% to 7% markup to your bill. Always choose the local currency (THB/VND) and let your own card provider handle the conversion.
Many first-time backpackers carry a wad of INR notes assuming local money changers in Bangkok or Hanoi will take them. While some booths accept them, the exchange rates offered for Indian Rupees on the ground in Southeast Asia are absolutely abysmal. You can easily lose 10% to 15% of your money’s value in the conversion. Always carry clean USD bills or withdraw local currency directly from a low-fee ATM using a zero-forex card.
Swiping your regular domestic Indian credit card for everyday holiday expenses sounds convenient, but it carries heavy financial consequences. Most standard credit cards carry a hidden 3.5% foreign currency markup fee plus 18% GST on that fee for every single transaction. Over a two-week trip, these micro-fees accumulate into thousands of wasted rupees.
What Most Guides Don’t Tell You
If you ignore this HDFC ForexPlus card review and carry it anyway loaded with USD, you will face the quiet double-conversion trap. When you buy a coffee in Vietnam, the local merchant bills your card in VND. Your card provider converts those Vietnamese Dong into US Dollars to deduct it from your loaded USD wallet, hitting you with a 2% to 3.5% markup. But remember, you originally bought those US Dollars using Indian Rupees back home, where you already paid a currency conversion margin. You are losing money on both sides of the transaction.
If you follow the strategy of carrying US Dollars to exchange locally, the condition of your currency notes matters immensely. Money changers in Vietnam and Thailand are incredibly strict. If your $100 bills have minor tears, ink marks, heavy creases, or are from older series designs, local booths will outright reject them or offer a significantly lower exchange rate. Always ask your Indian forex vendor for crisp, uncreased, series-2013-or-newer bills.
FAQ
What is your HDFC ForexPlus Card Review for Southeast Asia?
The HDFC ForexPlus card is obsolete for an itinerary spanning Thailand, Vietnam, Laos, and Cambodia. Because it does not support local currencies like VND, LAK, or KHR as base options, every transaction triggers an expensive 2% cross-currency markup alongside standard application and reloading fees.
What is the TCS rate on international travel from India?
Following the Budget 2026 revisions, booking a standalone overseas tour package incurs a flat 2% TCS from rupee one. For general international card spending or loading forex, a 20% TCS kicks in only after crossing a combined financial threshold of ₹10 lakh in a fiscal year.
Are Indian credit cards accepted in Thailand and Vietnam?
Yes, Indian credit cards are widely accepted at major malls, hotels, and established restaurants across Thailand and Vietnam, but they carry standard bank markup fees of 1.5% to 3.5% plus GST. Cash remains absolutely mandatory for local street food vendors, markets, and regional transport.
How much cash should I carry to Southeast Asia?
It is highly recommended to carry approximately $200 to $400 USD in pristine, uncreased cash notes per person. This ensures you can cover cash-only Visa on Arrival fees in Laos or Cambodia and get the highest conversion value at competitive local city-center currency exchange booths.
What is the best zero forex markup card in India?
The Niyo Global Card or the IDFC FIRST WoW Credit Card are the top choices in 2026 because they bypass traditional locked-in bank setups. They store your money securely in INR and offer real-time conversions into local currencies with zero cross-currency surcharges.
