Best Card to Use in Europe in 2026: The Real Cost in Euros

On a trip with €2,000 in expenses in Europe, the cheapest card available to Brazilians in 2026 costs about R$35 in fees. The "Global" card from your digital bank costs between R$610 and R$800. A traditional credit card can exceed R$1,000. It's the same euro spent in the same places; the difference lies entirely in the fee structure of the card you carry in your wallet.

Most guides on the best card to use in Europe list six options and conclude that "they all come out to around 5%." That number is right for the market average, and wrong for the best available in 2026. Spending in euros has a peculiarity that changes the math: besides the IOF (Brazilian financial operations tax) and the issuer's spread, there is the Visa network's exchange margin, which every non-dollar purchase pays. Understanding these three costs separately is what allows you to choose a card that zeroes out almost everything.

Picnic is a technology platform that has operated globally since 2021 and offers, in Brazil and Europe, an international account with a Visa card tied to a digital dollar balance. The data in this article was verified in June 2026.

Summary: the cheapest card for Europe in 2026

The values assume €2,000 spent at European merchants, a reference exchange rate of approximately R$5.90 per euro (June 2026), and the midpoint of the ranges disclosed by the issuers. The following sections explain, piece by piece, where each number comes from, and why the digital dollar option breaks the 5% rule.

Why spending in euros costs differently than spending in dollars

When you swipe your card in the United States, the purchase is already in dollars and your Picnic balance is also in dollars, so there is no conversion at all and the cost is literally zero. This is the scenario in our guide on the best card to use in the US.

In Europe, the purchase is in euros. This requires a conversion (from your balance to euros), and every currency conversion on the Visa network carries an exchange margin from the network itself, of approximately 0.3%. This margin is the same for every Visa card on the planet, from Picnic to a bank credit card. The difference between cards is not in this margin, but in everything that comes on top of it: the IOF and the issuer's spread.

That is why, in euros, no one reaches zero cost, but a card that zeroes out IOF and spread gets very close: only the unavoidable Visa margin remains. The result is a cost of about 0.3% versus the 5% to 9% of other options.

The 3 costs of a card in Europe

Every card used in Europe charges a maximum of three layers of costs on the purchase. Those who understand all three can choose a card that eliminates two of them.

1. IOF (Tax on Financial Operations)

Since July 2025, the IOF has been unified at 3.5% for purchases abroad with credit, debit, and prepaid cards. The rule is in Decree 12.499/2025. For most cards, it is the largest component of the cost of a trip to Europe.

There are two reduced rates worth mentioning:

• 1.1% for remittances to one's own investment account abroad, the path that Wise's Saldo Rende+ uses to reduce the IOF on card purchases.
• 0% on the path used by Picnic. BCB Resolution No. 521/2025 classified certain operations with digital dollars as foreign exchange operations, and the incidence of IOF (3.5%) on transactions with cards in this category still depends on complementary regulation. Currently, no IOF is levied on these transactions.

For a complete treatment of the topic, see the guide on what IOF is.

2. Issuer's spread

This is the margin that the bank or fintech adds to the euro exchange rate. It ranges from 0% (Picnic) to over 4% on some traditional credit cards. It is the most opaque part of the math, because almost no issuer publishes this margin separately: it comes embedded in the exchange rate that appears on the invoice. The concept is detailed in exchange spread.

3. Visa network exchange margin

The layer that exists only on non-dollar purchases. The Visa network applies its own exchange margin on the conversion, of approximately 0.3%, and you can check the rate used on the official Visa exchange rate calculator. Because it is a network margin, not an issuer margin, every Visa card pays it, including Picnic. It is the cost floor for any purchase in euros, and the reason no card reaches zero cost in Europe.

There is also a fourth charge, behind the scenes: the ISA fee of about 1% that Visa charges the issuer on international transactions. Most cards pass this fee on to the customer, embedded in the final cost. Picnic absorbs the ISA fee, so it doesn't enter your math. That is why, in the comparisons below, the cost of the other options tends to be about 1 percentage point higher than the simple sum of IOF plus spread suggests.

Comparison: card options for Europe

Each type of card combines these three layers in a certain way. See the options, what each does well, and where it weighs on your wallet.

Picnic

Zeroes out the IOF and the issuer's spread, leaving only Visa's exchange margin (~0.3%). On €2,000, that's about R$35. It is the lowest total cost available in Brazil for spending in euros. The card works with Apple Pay and Google Pay, has virtual cards, has no annual fee, and is tied to a digital dollar balance, so it works like debit: you spend what you have.

On a trip that combines the Eurozone, the UK, Switzerland, and the Czech Republic, you continue using the same card and the same USD balance. Pay in EUR, GBP, CHF, or CZK; Visa converts each purchase to your dollar balance. There is no need to buy four currencies, switch balances in the app, or separate one card per country. The guide on the Picnic card's dollar balance explains this convenience. It is still worth bringing a backup payment method, because no card has guaranteed acceptance at every merchant.

A fair warning: because it is debit, there is no credit limit, installment plans, or traditional points accumulation. This trade-off is in the analysis of the disadvantages of the Picnic card, and helps to understand who the Picnic card makes sense for.

Global accounts and exchange fintechs (Wise and similar)

They are a solid option and much cheaper than a traditional bank. Wise uses a rate close to the commercial rate, with a spread starting at about 0.78%, and charges a 3.5% IOF on the standard path (or 1.1% if the balance first passes through an investment account, in the Saldo Rende+ path), as detailed in Wise's official fees. It is predictable and transparent in its fees, and the detailed comparison between Picnic and Wise shows where each has the advantage. The weak point for Europe is the 3.5% IOF in common use, which alone already exceeds Picnic's total cost.

Digital bank "Global" Card (C6, Inter, Bradesco)

Convenient for those who are already customers, with the whole account in a single app. It pays the 3.5% IOF and adds a spread of 0.4% to 2% depending on the issuer, in addition to passing on Visa's ISA fee. The total cost tends to be between 5.2% and 6.8% on euro spending. It's usually worth it for the convenience, not the price.

Traditional credit card

Has the advantage of the billing cycle and points, useful for those who use mileage programs. In terms of travel cost, it is generally the most expensive: 3.5% IOF, a spread that can reach 4%, and the passed-on Visa ISA fee, totaling from 5.8% to almost 9% on the purchase. If your strategy is to earn points, it makes sense; if it is to spend less, it doesn't.

Cash (euro)

Useful as a backup for tips, street markets, and places that don't accept cards. But exchanging reais for euros at an exchange bureau is usually expensive due to the spread, and walking around with a lot of cash carries obvious risks. Take a small amount and handle the bulk on the card.

Euro or real? Never agree to pay in reais in Europe

In shops, restaurants, and ATMs in Europe, the machine sometimes offers to charge "in reais" instead of euros. This is called Dynamic Currency Conversion (DCC). Always refuse and choose to pay in euros.

The conversion done by the merchant uses a much worse exchange rate than your card's and also adds an extra margin, which always makes the purchase more expensive. The rule is simple: pay in euros everywhere and let your card do the conversion.

On Picnic, DCC is disabled on the card. If a purchase is sent using this conversion, it is not authorized and must be redone in euros. The machine may still show the offer to pay in reais or dollars, so select the local currency right from the start. The full reasoning is in paying in reais or local currency, and the product protection is in the guide on how Picnic blocks DCC.

Withdrawing euros at an ATM in Europe

Withdrawals have separate rules from purchases. Generally, the issuer charges a fee per withdrawal and the European ATM operator charges another, in addition to the 3.5% IOF that also applies to withdrawals abroad. Therefore, withdrawing should be an exception, not a routine: ideally, pay with the card whenever possible and use withdrawals only for the little that needs to be in cash.

Picnic supports withdrawals on the Visa network, subject to network costs and limits per operation; it is worth checking the limit and direct cost in the app before traveling. The general rules for withdrawing abroad are in ATM withdrawals abroad.

Credit, debit, or prepaid: what changes in practice

• Credit: gives you a billing cycle and points, but is the most expensive in fees and exposes you to exchange rate risk until the closing date, because the rate applied is from the day of conversion, not the day of purchase.
• Debit tied to a balance (Picnic's case): you spend what you have, with no surprises on the bill and no risk of the exchange rate moving against you after the trip. For a travel budget, it is usually the most predictable format.
• Traditional prepaid: locks in the exchange rate upon loading, but usually charges issuance and reload fees and still pays the 3.5% IOF.

If your priority is to spend less and have predictability, debit tied to a digital dollar balance works best. If the priority is to earn points, credit has its place. It is worth understanding how an international card works before deciding, and remembering that a good travel card doesn't need to have an annual fee.

How much cash to bring

There is no magic number, but a practical reference: bring enough euros for the first two or three days and for situations without a card (local transport, tips, street fairs). The rest is handled on the card, which almost always comes out cheaper than euros bought at an exchange bureau. For a one- to two-week trip, something between €150 and €300 in cash usually covers the essentials without leaving too much money sitting idle.

Some destinations have particularities that change this math. In Spain, for example, the VAT refund for tourists from outside the European Union has no minimum value and is refunded to the card, which gives another reason to concentrate purchases on plastic: the details are in the card guide for Spain. In Germany, card acceptance coexists with the frequent use of cash; see the card guide for Germany.

Final summary

For euro purchases in Europe, three costs define the price: IOF (3.5% on the standard path), issuer spread (0% to 4%), and the Visa network's exchange margin (~0.3%), the latter being unavoidable on any card. Picnic zeroes out the first two and is left only with Visa's margin, which results in about a 0.3% total cost, the lowest in Brazil for spending in euros. Global accounts come next, better than the traditional bank, but still carrying the 3.5% IOF in common use. Bank credit cards make sense for those who earn points, not for those who want to save money.

Before your next trip to Europe, take the amount you plan to spend in euros and multiply it by 5%. That is the approximate cost if you use the standard bank card, and it almost always equals a night at a hotel or a couple of dinners. Request your Picnic card and take that amount on the trip, not on the bill.
