Travelling Abroad: Credit Card vs Cash vs Forex Card

The three ways to pay abroad

When you travel internationally, you have three primary payment methods:

1. Credit card — 0% to 3.5% forex markup depending on the card.
2. Cash — exchanged at a bank, forex counter, or airport.
3. Forex (multi-currency) card — a prepaid card loaded with foreign currency.

Each has a role. The right mix depends on the trip, the destinations, and the spend pattern.

Credit cards: best for high-value spend

A credit card with 0% forex markup (HDFC Infinia, Diners Club Black) is the cheapest way to pay internationally. The transaction is in the local currency; the bank converts at the network's posted rate with no markup. You pay the merchant in local currency; the bank sends you the bill in rupees at the day's rate.

On ₹10 lakh of international spend:

• 0% markup card: ₹10,00,000 (no fee).
• 1.5% markup card: ₹10,15,000.
• 2% markup card: ₹10,20,000.
• 3.5% markup card: ₹10,35,000.

The savings on a 0% markup card vs a standard card: ₹15,000–₹35,000.

Credit cards also offer:

• Fraud protection via the card network's dispute process.
• Insurance: many premium cards include travel insurance.
• Lounge access at airports.
• Reward points on international spend (HDFC Infinia 5 points per ₹150, Axis Atlas 5 EDGE Miles per ₹100 on travel, Amex Platinum Travel 5 MR per ₹100 on travel).

The downside:

• Merchant acceptance: some small merchants abroad don't accept credit cards. Cash is needed as backup.
• Dynamic currency conversion: if the merchant offers to charge you in INR vs local currency, always choose local currency. The bank's markup is lower than the merchant's DCC rate (typically 3%–5%).

Cash: best for small merchants, tips, and emergencies

Cash is the universal payment method. Most international merchants, even small ones, accept cash. Tips, taxis, and street food typically require cash.

The cost of cash:

• Indian bank forex card (Thomas Cook, BookMyForex): ₹500–₹1,000 fee plus the exchange rate (typically 1%–2% markup over mid-market).
• Airport forex counters: 2%–3% markup over mid-market.
• Hotel forex: 3%–4% markup.
• Bank branch: 1%–2% markup for non-customers, 0.5%–1% for priority banking customers.

A €1,000 cash withdrawal at an airport counter costs ₹90,000–₹92,000 at typical rates (vs ₹84,000 at mid-market). That's ₹6,000–₹8,000 in fees.

Best practice:

• Buy forex from your bank before the trip. Priority banking customers get the best rates.
• Carry enough for the first 24 hours: taxi from airport, hotel incidentals, food.
• Carry the rest on a credit card (0% markup) and use ATMs as needed (with your debit card or credit card).
• Avoid airport counters for large exchanges.

Forex (multi-currency) cards: best for budget control

A forex card is a prepaid card you load with foreign currency before the trip. You can lock in the rate at the time of loading. The card works at international ATMs and POS terminals.

Pros:

• Locked-in rate: you know exactly how much you'll spend.
• No forex markup on the card itself: only the loading fee (typically 1%–2%).
• Safer than cash: if lost, you can block the card and recover the balance.
• Budget control: you can only spend what's loaded.

Cons:

• Loading fees: typically 1%–2% of the loaded amount.
• Reloading fees: 1%–2% if you need more mid-trip.
• ATM withdrawal fees: ₹200–₹500 per transaction at ATMs.
• Card replacement: if lost, replacement takes 5–10 days.
• Less fraud protection than credit cards.

The right forex card strategy:

• Load 50% of your trip budget in foreign currency on the forex card (locks in the rate).
• Carry the rest on a 0% markup credit card (for high-value spend).
• Carry ₹10,000 in cash for emergencies.

The hybrid approach

A typical 7-day trip to Europe with ₹3 lakh spend:

Method	Amount	Fee	Net cost
Forex card (₹1.5L loaded at 1.5%)	₹1,50,000	₹2,250	₹1,52,250
Credit card (₹1L spent at 0% markup)	₹1,00,000	₹0	₹1,00,000
Cash (₹50,000 in EUR, bank rate 1%)	₹50,000	₹500	₹50,500
Total	₹3,00,000	₹2,750	₹3,02,750

vs all credit card (3.5% markup): ₹3,00,000 × 1.035 = ₹3,10,500 — that's ₹7,750 more than the hybrid approach.

vs all cash (airport rate 3%): ₹3,00,000 × 1.03 = ₹3,09,000 — that's ₹6,250 more than the hybrid.

The hybrid is the cheapest. The next step is to push more onto the 0% credit card and less on cash/forex.

What about dynamic currency conversion (DCC)?

If a foreign merchant offers to charge you in INR vs local currency, ALWAYS choose local currency. DCC typically adds 3%–5% to the transaction. Your bank's markup is 0%–3.5% — lower than DCC.

When a merchant's terminal offers "pay in INR", decline. The DCC rate is set by the merchant's acquiring bank, which is rarely competitive.

The bottom line

The cheapest way to pay internationally is a 0% forex markup credit card. The hybrid approach (forex card for budget + credit card for high-value + small cash reserve) is the safest and most flexible. Avoid airport forex counters, avoid DCC, and lock in your rate on a forex card before departure. For most Indian travellers, the savings vs all-cash or all-credit-card are ₹5,000–₹20,000 per trip.
