Forex Card vs Debit Card vs Cash in SE Asia (2026)
✅ Last verified on-the-ground: 2026-07-14
Forex card vs debit card abroad in 2026 comes down to markup and ATM fees. For Thailand, Vietnam, Laos, and Cambodia, skip the airport forex counter. A zero-markup debit card with ₹15,000-₹20,000 (~$157.08-$209.44) in cash for the first 48 hours is the cheapest, most reliable setup. This guide breaks down what every Indian traveller pays.
Quick Answers
| What | Answer | Price (INR) |
|---|---|---|
| Best payment method | Zero-markup debit card (Fi, Niyo, Jupiter) | ₹0 markup, ₹100-₹200 (~$1.05-$2.09) ATM fee |
| Best for cash on arrival | Forex card from HDFC/ICICI/SBI (loaded before flight) | 2%-3.5% markup, ₹0 ATM fee in some banks |
| Worst option | Airport exchange counter (Thailand/Delhi) | 5%-8% worse than mid-market |
| UPI in Southeast Asia | Works in Singapore and parts of Malaysia only | Not accepted in THB/VND/LAK/KHR as of 2026 |
| RBI TCS above ₹7L | 20% tax collected at source on amount over ₹7L | Paid upfront, refundable at ITR filing |
Quick rule: 1 THB = ₹2.8642, 1 VND = ₹0.0036, 1 LAK = ₹0.0043, 1 KHR = ₹0.0236, and 1 USD = ₹95.4928. If a counter in Bangkok offers you 1 THB = ₹2.86 that’s a 0.15% hidden haircut before any commission.
How it Works
Three things are happening every time you pay abroad, and most Indians never realise any of them.
The interbank rate. This is the real mid-market rate your bank’s treasury desk uses. In 2026, 1 USD sits around ₹95.4928. Banks never sell to you at this rate. They add a markup, usually 1.5% to 3.5%, and that’s their actual revenue on forex transactions.
The ATM fee. This is a flat charge on top, per withdrawal, charged by either your Indian bank, the foreign ATM operator, or both. A ₹630 (~220 THB or ~$6.60) ATM fee in Bangkok (₹630 (~$6.60)) is standard. A ₹182 (~50,000 VND or ~$1.91) ATM fee in Hanoi (₹180 (~$1.88)) is also standard. Some Indian banks refund this; most don’t.
DCC (Dynamic Currency Conversion). This is the scam. When you swipe your card at a shop or ATM, the terminal asks “pay in INR or THB?” Always choose THB. If you pick INR, the foreign merchant’s bank sets the rate, and it is always 3% to 7% worse than your bank’s rate. The shop gets a kickback. You pay for it. DCC is the single most expensive mistake Indian travellers make, and most don’t notice.
The Fi and Niyo cards work by charging you the real interbank rate (zero markup) and then letting the ATM’s own fee stand. On a ₹30,000 (~$314.16) withdrawal in Bangkok, you’d pay ₹0 markup + ₹630 (~$6.60) ATM fee. On an HDFC ForexPlus card, you’d pay ₹30,000 × 3% = ₹900 markup + ₹0 ATM fee (if your bank refunds it, which HDFC does on most ForexPlus variants). The difference per withdrawal is small. Over a 21-day trip with 8 to 10 ATM hits, it adds up to ₹2,500-₹4,000 (~$26.18-$41.89).

Comparison of Popular Options
Here’s what every Indian traveller in Southeast Asia is choosing between in 2026.
| Card / Method | Forex Markup | ATM Fee (Foreign) | Daily ATM Limit | UPI Works? | Verdict |
|---|---|---|---|---|---|
| Fi Zero-FX Debit | 0% | ₹100 (~$1.05)+ operator fee (~220 THB) | ₹100,000 (~$1,047.20) | No | Best overall for 2026 |
| Niyo Global Debit | 0% | ₹48 (~0.50 USD) + operator fee | ₹150,000 (~$1,570.80) | No | Best for high-volume ATM users |
| Jupiter Zero-FX | 0% | ₹100 + operator fee | ₹1,00,000 | No | Equal to Fi, smoother app |
| HDFC ForexPlus Card | 2%-3.5% | ₹0 (refunded by HDFC) | ₹200,000 (~$2,094.40) | No | Good if you load large lump sums |
| ICICI Travel Card | 2.5%-3% | ₹0 in some variants | ₹150,000 (~$1,570.80) | No | Older product, less competitive |
| Cash from Delhi airport | 4%-7% hidden | N/A | N/A | N/A | Avoid except for landing cash |
| Cash from Bangkok SuperRich | 0.5%-1% | N/A | N/A | N/A | Best for reloading cash mid-trip |
| Indian credit card (Visa/MC) | 3.5%-5% | ₹0 | Varies | No | Worst option, highest markup |
The key insight: a zero-markup debit card with a ₹100-₹200 (~$1.05-$2.09) ATM fee beats a forex card with zero ATM fee only if you withdraw fewer than 4 times per trip. On a 21-day backpacking loop through 4 countries, expect 8 to 12 ATM hits. At that volume, Fi and Niyo come out ahead by roughly ₹1,800-₹3,500 (~$18.85-$36.65).
Subodh’s Pro Tip: Load ₹15,000 (~$157.08) to ₹20,000 (~$209.44) in cash before you fly. Use it for tuk-tuks, street food, and the first night’s hostel. After that, your debit card takes over and you stop carrying cash in your pocket, which is its own safety win in Bangkok and Phnom Penh.
India-Specific Gotchas (RBI & TCS)
The Tax Collected at Source (TCS) rule is the single biggest gotcha for Indian travellers in 2026, and it has caught thousands of people off-guard.
Under the Liberalised Remittance Scheme (LRS), you can spend up to USD 250,000 per financial year abroad. That’s ₹2.38 (~$0.02) crore at current rates, well above what any backpacker needs. The trap is in the middle band.
For spending below ₹7 lakh per financial year on overseas tours, no TCS applies. The moment you cross ₹7 lakh on a single trip or cumulatively across trips in the same FY, the entire amount above ₹7L attracts 20% TCS. The bank collects this at source when you load your forex card or remit money. It is refundable when you file your ITR and can show the underlying spend, but most people don’t claim it because they don’t track receipts.
Safety Alert: 20% TCS on a ₹1.5 lakh trip is ₹30,000 (~$314.16). That money is locked with the government until you file your return. If you’re on a tight budget, structure your spending: load ₹6.5L on a forex card, pay for the rest via debit card or UPI remittance to a friend abroad. The ₹7L threshold is per financial year, not per transaction.
What you need to keep:
- Aadhaar and PAN linked to your bank account (mandatory for any forex card issuance in 2026)
- Original forex card load receipt (shows date, amount, TCS component)
- Air tickets and hotel bookings as proof of purpose
- Form A2 declaration at the bank branch (now mostly digital)

What Bananarchy Travellers Use
The setup that has worked with the fewest surprises is a three-layer stack: cash for the first 48 hours, a Fi or Niyo card as the workhorse, and a backup forex card from HDFC parked in the hostel locker.
The cash is non-negotiable. Vietnam still has entire districts in Hanoi and Saigon where street-side pho stalls and xe-om drivers take cash only, and Thai 7-Eleven tills under ₹286 (~100 THB or ~$3) in some provinces refuse card taps. We recommend ₹15,000 (~$157.08) to ₹20,000 (~$209.44) in USD, exchanged in Bangkok at SuperRich or Vasu if you can find a branch. Travellers report the Bangkok SuperRich rate is typically 0.5%–1% off mid-market, which beats every Delhi airport counter by a wide margin.
The zero-markup debit card is what you live on. Fi and Niyo both work in Thailand, Vietnam, Laos, and Cambodia without any prior intimation. In Cambodia, where the local currency (KHR) is tricky, you can opt for USD withdrawals at most major bank ATMs (ABA, Canadia, Sathapana), and the conversion happens at a much better rate than any money changer. The card works the same way.
The backup forex card is your disaster insurance. If your primary card gets blocked for “suspicious activity” (it happens, often after the first 5 or 6 foreign transactions), the forex card is what gets you home. We recommend loading ₹10,000 to ₹20,000 on an HDFC ForexPlus card and not touching it. It’s a safety net, not a daily driver.
A note on Vietnam: many Vietnamese ATMs have a ₹182 (~50,000 VND or ~$1.91) operator fee on top of any fee your Indian bank charges, which on a small withdrawal can feel high. The trick is to withdraw the maximum allowed per transaction, usually ₹18,230 (~5,000,000 VND or ~$190.90), and the fixed fee becomes 1% to 2.5% of the withdrawal. Same logic applies in Laos (₹4,273 (~$44.75), ~2,000,000 per hit) and Cambodia (₹19,099 (~200 USD) per hit.
Subodh’s Pro Tip: Always decline the conversion at the ATM screen. Vietnamese, Thai, Lao, and Cambodian ATMs all offer to convert to INR at a poor rate. Hit “no thanks” and let your Indian bank do the conversion, which is always cheaper.
Getting Connected
You need data to check exchange rates, get bank fraud alerts, and run UPI apps. We recommend a local SIM from AIS (Thailand), Viettel (Vietnam), Unitel (Laos), or Smart (Cambodia) for the trip. If you want zero hassle, a regional eSIM is the easier option. Pick the country pack on landing, activate, and you’re online in 10 minutes. No passport scan, no shop visit, no Thai SIM registration video.
FAQ
Does UPI work in Thailand, Vietnam, Laos, or Cambodia?
No. As of 2026-07-14, UPI acceptance is limited to Singapore and parts of Malaysia, plus a few merchant tie-ups in the UAE. Thailand, Vietnam, Laos, and Cambodia have no UPI infrastructure. Don’t plan around it. For a country-by-country UPI map, see our Cambodia UPI guide.
What happens if I lose my forex card abroad?
Call the Indian bank’s 24x7 international helpline (printed on the card) and block it. The bank will courier a replacement to your hotel within 3 to 5 working days. You will not have access to the loaded amount during that window, so always keep a backup: either a second forex card or a zero-markup debit card. For the deeper review of Niyo as a backup, see our Niyo card review.
How much cash can I take out of India in foreign currency?
The RBI cash cap is roughly ₹2,86,000 (~3,000 USD) per trip, and under LRS you can remit up to USD 250,000 per financial year (subject to applicable TCS). For most backpackers, ₹3,000 USD in cash is well over what’s needed for a 3-week trip. If you need more than that, use a forex card, which has no per-trip cash limit but still counts toward the LRS ceiling. Above ₹7L per FY, expect 20% TCS.
Is the markup on a forex card refundable?
No. The 2% to 3.5% markup baked into forex cards is the bank’s revenue. It is not a tax, fee, or charge you can claim back. It is a worse exchange rate than the interbank rate. Zero-markup debit cards exist precisely to avoid this.
Should I get a forex card in 2026 if I already have Fi or Niyo?
Only as a backup. The primary use case is a frozen-card emergency. Load ₹10,000 (~$104.72) to ₹20,000 (~$209.44), lock it in your bag, and forget about it. If you do want to use it as a primary tool, see our HDFC ForexPlus review for the actual numbers, but the short answer is: zero-markup debit wins in 2026.
Subodh’s Take
A forex card made sense in 2018 when zero-markup debit cards didn’t exist for Indians. In 2026, they do, and a forex card is a backup, not a primary. The single biggest mistake I see travellers make is loading the full trip budget on a forex card and then feeling locked in, ending up with leftover foreign currency they can’t easily reconvert in India without another 2% haircut. A zero-markup debit card solves that. You can leave the trip with zero in your account, no leftover forex, no ITR reconciliation.
