A forex card for Thailand is the calmest way to carry money once you land in Bangkok or Phuket — it locks your exchange rate before you fly and shields you from the messy markups at airport counters. Unlike a regular Indian debit card, a prepaid forex card is built for foreign spending, so swipes and ATM withdrawals cost far less. This guide is the practical side of things: which currency to load, what fees actually hit you on the ground, and the small mistakes I see Indian travellers make every season. Updated for 2026 with current RBI and TCS rules.

Why a forex card for Thailand makes sense
Thailand runs largely on cash, but the smarter play is a mix — some Thai baht in hand and the rest on a forex card for Thailand. The card protects the rate you locked in India, so a weak rupee day mid-trip doesn’t eat into your budget.
- Cheaper abroad: Indian debit/credit cards add a 3–3.5% foreign currency markup on every swipe. A forex card typically has none once loaded.
- Rate certainty: You know your INR-to-THB rate at purchase, not at spend.
- Safety: If lost, the card is blocked and reissued — cash is simply gone.
- Backup: Keep it separate from cash so you’re never fully stranded.
For a beach-and-street-food trip, a card plus a modest cash float covers almost everything.
Which currency should you load — USD or THB?
This is the single biggest decision, and most people get it wrong. Thai baht (THB) is not offered on many Indian forex cards, so travellers default to loading US dollars — then pay a hidden conversion each time they spend.
- Load THB if available: Every swipe and ATM withdrawal in Thailand happens in baht with no cross-currency conversion. This is the cheapest option.
- If only USD is offered: Every Thai transaction triggers a USD→THB cross-currency fee, usually 2–3.5%.
Before buying, ask your bank plainly: “Does this card support Thai baht as a load currency?” Cards from banks like HDFC, ICICI, Axis and providers such as Niyo or BookMyForex vary. Loading the local currency directly is the clearest way to avoid double conversion.
Real fees to expect on the ground
The card itself is cheap; the fees live in how you use it. Here’s what typically applies as of 2026 — always confirm the exact figures on your provider’s schedule.
- ATM withdrawal (issuer fee): roughly THB equivalent of USD 2–3 per withdrawal.
- Thai bank ATM surcharge: a flat THB 220 is charged by most Thai ATMs to foreign cards — this is on top of your issuer’s fee and is unavoidable at bank machines.
- Cross-currency markup: 2–3.5% if you loaded USD instead of THB.
- Reload/inactivity fees: vary by provider; some charge for reloads or dormant balances.
The THB 220 surcharge is why you should withdraw larger amounts less often, not small sums daily.
TCS and RBI rules you can't skip
Loading a forex card counts as a foreign remittance under the RBI’s Liberalised Remittance Scheme (LRS), so two rules matter for your Thailand trip.
- LRS limit: You can remit up to USD 250,000 per financial year for travel and other permitted purposes — far above any tourist need.
- TCS (Tax Collected at Source): As of 2026, forex card loads for travel above ₹10 lakh in a financial year attract 20% TCS; loads up to ₹10 lakh are generally exempt.
The TCS is not a tax you lose — it’s adjustable against your income tax liability or refundable when you file returns. Keep the load receipt. For a normal 7–10 day Thailand holiday, you’ll almost certainly stay under the threshold and pay no TCS at all.
How much to load for a Thailand trip
Overloading strands money on a card you may not touch for months; underloading means costly emergency reloads. A rough per-person daily budget helps.
- Budget travel: THB 1,500–2,500/day (hostels, street food, local transport).
- Mid-range: THB 3,000–5,000/day (3-star hotels, some tours, mixed dining).
- Comfort/family: THB 6,000+/day (resorts, private transfers, activities).
Multiply by trip days, add a 10–15% buffer, and load that. Carry roughly THB 3,000–5,000 in cash on arrival for taxis, small vendors and tips — many street stalls and tuk-tuks are cash-only. Keep the rest on the card and reload online if you run short; most providers let you top up from the app within a day.
Where a forex card works — and where it won't
Card acceptance in tourist Thailand is good but not universal, so plan for both.
- Works well: malls, chain restaurants, hotels, 7-Eleven, supermarkets, airport shops, and most ATMs.
- Cash preferred: street food stalls, night markets, tuk-tuks, small guesthouses, temples, and island vendors.
Use the card for larger, card-friendly payments and keep cash for the small stuff. One important tip: when a machine or terminal asks whether to charge in THB or your home currency, always choose THB. Choosing INR or USD triggers Dynamic Currency Conversion (DCC) — a poor merchant-set rate that quietly adds 3–8%. Paying in local currency lets your forex card’s locked rate do its job.
Common mistakes Indian travellers make
Most forex card losses on a Thailand trip aren’t bad luck — they’re avoidable habits.
- Loading USD when THB was available — paying cross-currency fees on every swipe.
- Accepting DCC — tapping “charge in INR” at the terminal.
- Frequent small ATM withdrawals — the flat THB 220 surcharge hits every time.
- Not carrying arrival cash — stuck at a cash-only airport taxi queue.
- Forgetting the backup card/PIN — a blocked primary card with no fallback.
- Ignoring the leftover balance — unspent baht sitting idle for months.
Carry the card and its backup in separate bags, note the 24×7 helpline before you fly, and set a low-balance alert. These small steps save real money and stress.
Before you fly: a quick checklist
Run through this the week before departure so nothing derails your first day in Thailand.
- ☑ Confirm your card is activated and PIN is set.
- ☑ Load in THB if possible, or USD as a fallback.
- ☑ Note the provider’s 24×7 international helpline and block number.
- ☑ Keep the load receipt for TCS records.
- ☑ Carry a backup card and some cash stored separately.
- ☑ Save the mobile app login for on-the-go reloads.
- ☑ Test one small transaction before relying on it fully.
Remember a valid passport and, for most Indian tourists, Thailand’s visa exemption or e-Visa on Arrival rules — check the official Thai immigration site before booking, as entry rules can change.
Unloading leftover balance after your trip
Money left on a forex card for Thailand doesn’t have to be wasted. You have two clean options once home.
- Encash it: Ask your issuing bank to reverse the unused balance to your Indian account. A small encashment fee and the prevailing buy-back rate apply, so you may see a minor loss versus what you loaded.
- Keep it for next time: If you travel abroad again soon, retain the balance — most cards are valid for 3–5 years and reusable across countries.
Avoid leaving small balances idle indefinitely, as some providers levy inactivity fees. Decide within a few weeks of returning. If your card supported multiple currencies, remember leftover THB can also be spent on a future Thailand or neighbouring-country trip.

Frequently asked questions
Should I load Thai baht or US dollars on my forex card for Thailand?
Load Thai baht (THB) if your provider offers it, because every Thai transaction then happens with no cross-currency conversion. If only USD is available, you'll pay a 2–3.5% conversion fee each time you spend in Thailand, so THB is the cheaper choice.
Do I pay TCS when loading a forex card for a Thailand trip?
As of 2026, forex card loads for travel are exempt from TCS up to ₹10 lakh in a financial year. Above that, 20% TCS applies, but it's adjustable against your income tax or refundable when you file returns. A normal Thailand holiday stays well under the limit.
What ATM charges apply when using a forex card in Thailand?
Most Thai bank ATMs charge a flat THB 220 surcharge to foreign cards, on top of your issuer's withdrawal fee of roughly USD 2–3. To reduce cost, withdraw larger amounts less frequently rather than making small daily withdrawals.
Is a forex card better than my Indian debit or credit card in Thailand?
Usually yes. Indian debit and credit cards add a 3–3.5% foreign currency markup on every foreign swipe, while a forex card locks your rate and avoids that markup once loaded. A forex card is also safer, since it can be blocked and reissued if lost.
What should I do if the terminal asks to charge in INR instead of THB?
Always choose Thai baht (THB). Choosing INR triggers Dynamic Currency Conversion, where the merchant sets a poor exchange rate that adds roughly 3–8%. Paying in local currency lets your forex card use its own locked rate.
Can I get leftover money back from my forex card after Thailand?
Yes. You can ask your issuing bank to encash the unused balance back to your Indian account for a small fee at the buy-back rate, or keep the balance for a future trip since most cards stay valid for 3–5 years.
