Debit card or credit card: the real difference

A debit card takes the money from your current account within one to two days. A credit card groups your purchases and charges them on a fixed date, and some let you carry the balance forward against interest. The timing of the charge, though, is not the difference that costs you money.

What is the difference between a debit card and a credit card?

The money. On a debit card it leaves your current account within one to two working days. On a credit card the issuer pays the retailer on your behalf and recovers the whole amount on the statement date, once a month.

That two-way split is the brochure version. A third case is missing, and it is the one that sets the price. A credit card can sit on a simple monthly payment facility, or on a credit facility that allows the balance to be carried forward. The first is a payment services contract. The second is a credit contract, governed by Book VII of the Belgian Code of Economic Law, with its pre-contractual disclosure duties, its withdrawal period and its capped APR.

The comparison table published by Wikifin, the consumer site of the FSMA, the Belgian financial regulator, was updated on 14 July 2026 and covers the first two columns. The third one, the column that generates interest, gets a single line there.

Are deferred debit and credit the same thing?

No, and that confusion cost me more phone time than anything else in seven years.

Take the Argenta credit card. It carries a Mastercard logo, it is accepted anywhere a credit card is, and the fee is EUR 2.00 per month on the Green package, so EUR 24.00 over twelve months. Look for its APR in the issuer's rate card, valid from 17 August 2026: there is none. There is none because there is no credit facility behind it. The monthly balance is charged in full, so there is nothing to carry forward and nothing to bill.

Now take the Beobank Smart Travel Mastercard. Its Standard European Consumer Credit Information sheet, the document required by article VII.70 of the Code of Economic Law, states a credit facility linked to the card, an actuarial borrowing rate of 12.46 % and an APR of 14.49 %. The annual fee is EUR 30.00. Rates recorded from the issuer on 25 August 2026.

Two cards, two Mastercard logos, two mechanisms with nothing in common. The figure to remember: on the second one, interest is calculated daily on the outstanding balance for as long as the total amount due is not repaid.

How much does a EUR 100 withdrawal cost on each card?

This is where the gap shows without any arithmetic.

On an Argenta debit card, a euro withdrawal at a cash machine inside the SEPA area is free. On the same issuer's credit card, that withdrawal costs EUR 6.00. At Beobank, a withdrawal is billed at 2.50 % of the amount with a EUR 5.00 minimum and a EUR 15.00 maximum per operation: on EUR 100, the minimum applies, so EUR 5.00.

Over twelve months, one withdrawal a month at EUR 6.00 comes to EUR 72.00. That is three times the card's annual fee.

The brochure leaves out the following point. On a credit facility, a cash withdrawal is a credit drawdown. Interest runs from the day of the operation, with no grace period, even if you repay everything at the end of the month. A payment at a retailer gets that grace period; a withdrawal does not.

Which one protects you when the merchant does not deliver?

The credit card, and not because any law says so.

Chargeback is a network rule. Visa Belgium writes it without hedging on its own page: it gives you no legal right to a refund. The situations covered are non-delivery, merchant bankruptcy, damaged or counterfeit goods, the wrong amount, a double charge, and billing that continues after a subscription is cancelled. The procedure always starts with an attempt to settle with the merchant, then a dispute form filed with the issuer.

Bancontact works differently. The Belgian domestic scheme guarantees settlement to the merchant and provides no chargeback route. A customer who paid by Bancontact at a Belgian merchant that has gone under has no file to open: what remains is a claim filed with the liquidator. Visa Debit and Debit Mastercard cards, by contrast, run over the international networks and reopen that door.

In the files I handled, the dispute most often refused was not the weakest one: it was the latest one. A holder who waits six months before flagging a subscription billed in error runs into the network deadlines, which are counted in tens of days from the transaction date, not in months.

Who refunds a fraudulent charge, and up to how much?

The issuer, in both cases, and the regime is the same for a debit card and for a credit card.

Book VII of the Code of Economic Law sets out how liability is shared between the holder and the payment service provider. For an unauthorised payment transaction, the loss borne by the holder is in principle capped at EUR 50, barring fraud or gross negligence on their part. Article 73 of PSD2 requires the refund by the end of the first working day after the provider becomes aware of the transaction. You have up to thirteen months from the transaction to dispute it.

Gross negligence has no legal definition. It is assessed case by case by the courts, and that vagueness is what the issuer leans on when it refuses.

The issuer looks at three things first: whether the PIN was entered correctly on the first try, whether strong authentication was validated on your phone, and how much time passed between the first disputed transaction and your call. Three objective elements, drawn from the technical logs, read before your account of events.

Why does a car rental company refuse a debit card?

Because of the pre-authorisation, which is a hold on funds rather than a payment.

On a debit card, that hold bites into money actually sitting in your current account. It fails if the balance is too low, and it ties up your money for the whole rental period. On a credit card, it consumes part of the monthly limit granted by the issuer: the rental company gets room to charge even if your account is empty, which is exactly what it is after.

Hotel and car rental deposits that stay blocked for two or three weeks after the vehicle is returned are a classic of the disputes desk. Release depends on the merchant, who has to send an authorisation reversal, not on your bank.

Three situations where a debit card is more than enough

• Cash withdrawals in Belgium. Wikifin recommends this explicitly: to withdraw cash in Belgium, a debit card avoids the per-operation charges a credit card applies.
• Everyday spending at a Belgian retailer. Inside the euro area, a debit card transaction costs the same as it does in Belgium.
• A trip inside the euro area, provided you check two points before leaving: most Belgian debit cards are blocked by default for use outside Europe and have to be unblocked by the bank; outside the euro area, an exchange margin applies, around 2.00 % at Argenta on a foreign currency payment, plus EUR 0.60 per operation, rate recorded on 25 August 2026.

As soon as it involves a sizeable online purchase, a plane ticket, a deposit on a trip or an open-ended subscription, the credit card opens a route to recourse that the domestic debit card does not have.

The three figures to compare before you sign

Take them in this order: the annual fee in euros, the APR applied to a carried balance where one exists, and the cost of a EUR 100 withdrawal at a cash machine. Insurance and points come afterwards, never before. The legal maximum APR in Belgium is set by the Royal Decree of 14 September 2016 and revised every six months, with publication in the Belgian Official Gazette; the rates in force are available on the FPS Economy website.

The ranking of Belgian credit cards sets out these amounts card by card, the comparison tool places them side by side, and the choosing a card page sorts by situation rather than by product.
