Travel card choice: what makes one actually good abroad
The ideal travel card has nothing to do with airline miles. Here is what to actually look at before your next trip beyond the eurozone.
Travel-card marketing is relentlessly about perks — lounge access, airline miles, travel insurance. For most trips, these are either illusory or less valuable than the plain mechanical qualities that make a card useful at a foreign terminal. Here is the actual checklist, in rough order of impact.
1. FX spread
How far above the mid-market rate does your card convert? Legacy bank cards: 2-3% spread. Decent neo-bank cards: 0.3-1%. On a 2-week trip with €2,000 of foreign spend, a 2% spread costs €40. Over a decade of travel, this is the single biggest lifetime cost difference between cards.
2. No foreign transaction fee
Separate from the FX spread, some cards charge an additional 1-3% "foreign transaction fee" on every non-domestic transaction. A card without this fee saves you another €20-€60 per trip.
3. ATM withdrawal allowance
Monthly free ATM withdrawals abroad before fees kick in. €400-€1,000/month is reasonable for a traveller; some cards cap at €200 which is painful on longer trips.
4. Chip + contactless universal acceptance
Almost all cards have this now, but double-check if you have an older product. Some US-issued cards still ship with magnetic-stripe-only in parts, which creates friction at EU chip terminals.
5. 3DS / SCA support that actually works abroad
When you make an online purchase while roaming, 3DS verification normally sends a push to your bank app. If your bank app auth depends on SMS, roaming can break this. Test before you travel — attempt an online purchase from a foreign IP and see what the auth flow looks like.
6. Instant freeze/unfreeze
Essential for a lost or stolen card. Modern app-based cards freeze in one tap. Legacy banks require a phone call that may be long-distance from where you are.
7. Mobile wallet (Apple Pay / Google Pay)
Universally accepted and more secure than physical card in most places. If your card does not support mobile wallet, that is a strong signal you should get a different card.
What is NOT worth optimising for
Airline miles on a card you use occasionally — the earn rate is almost always below 1% of spend. Lounge access that requires status you do not have. "Travel insurance" from credit cards that is almost never useful in practice (your home contents or travel insurance will have better coverage).
Our practical recommendation
Carry two cards from two different schemes (Visa + Mastercard) in case one is declined for anti-fraud reasons at a foreign terminal. Keep one in your luggage and one on you. Make sure both support mobile wallet. For eurozone cards travelling outside the eurozone, 0.5% or lower FX spread, free monthly ATM withdrawals of €400+, and instant freeze is the specification.
