What are credit cards in Portugal?

A credit card (cartao de credito) lets you spend up to a set limit and repay later, either in full each month or in instalments, with interest charged on unpaid balances. In Portugal, credit cards commonly offer a revolving option where you can pay a minimum and spread the rest, plus interest-free periods if the balance is cleared. Cards provide payment convenience, online and travel security, and sometimes rewards, cashback or travel insurance. They differ from debit cards, which draw directly on your account, by giving access to short-term credit.

How the Portuguese market works

Credit cards are issued by banks and, increasingly, by fintech and retail-partner brands. Portuguese cards run on the Multibanco (MB) network domestically as well as Visa or Mastercard internationally, and MB WAY lets you link cards for mobile payments. Interest applies to revolving balances, with rates capped by the Banco de Portugal maximum TAEG for credit-card lending, updated quarterly. Cards vary by annual fee, interest-free period, rewards, and whether repayment defaults to full or partial. Stamp duty applies to interest and to some card fees.

Benefits

Interest-free period — pay the full balance by the due date to avoid interest on purchases.

Flexible repayment — spread larger costs over months via the revolving option when needed.

Purchase security — strong protection for online and travel spending, plus fraud safeguards.

Rewards and perks — some cards offer cashback, points, discounts or travel cover.

How to choose

Decide how you will use the card: if you always pay in full, prioritise a low or no annual fee and good rewards; if you will carry a balance, focus on the lowest TAEG. Check the interest-free period length, the annual fee, and whether repayment defaults to partial (which accrues interest). Compare rewards, cashback and included insurance against the fee. Watch cash-advance charges and foreign-transaction fees, and confirm the rate sits within the Banco de Portugal cap.

Leading providers in Portugal

Caixa Geral de Depositos, Banco BPI, Millennium BCP, Novo Banco and Santander Portugal issue the main bank credit cards, spanning basic, rewards and premium tiers. Banco Montepio and Banco BEST offer competitive cards, and Banco CTT provides accessible cards through the postal network. Retail and co-branded cards add cashback and store rewards. Because annual fees, interest rates and reward structures differ widely, comparing the TAEG and fee against how you intend to repay is the key to choosing well.

What it costs

Credit-card costs in Portugal comprise the annual fee (from free on basic cards to higher on premium rewards cards), interest on revolving balances charged at a TAEG capped by the Banco de Portugal, and stamp duty on interest. Additional charges include cash-advance fees, foreign-transaction fees outside the euro area, and late-payment costs. Paying the full balance each month avoids purchase interest entirely, making the annual fee and rewards the main cost consideration for full payers. Always check the preçario.

Protections and regulation

Credit cards are regulated by the Banco de Portugal, which caps the maximum TAEG for revolving credit each quarter and enforces responsible-lending and disclosure rules. Cardholders benefit from Visa or Mastercard fraud protections and strong customer authentication under PSD2. Providers must show the interest-free period, TAEG and fees clearly, and repayment terms must be transparent. Outstanding balances are reported to the central credit register, and disputes over charges or fraud can be escalated to the issuer and the Banco de Portugal.
