Credit, debit or prepaid card: which one should you choose?

Many people call any card they take out of their wallet to pay a “credit card”. In practice, most of those cards are debit or prepaid cards, and the difference matters. Paying with money you already have is not the same as paying with money the bank advances to you, or with money you previously loaded onto a card. Each one comes with different requirements when you apply, different fees when you use it and different levels of protection if something goes wrong.

Knowing what type of card you carry changes how you manage your money, when one option makes more sense than another and what you can claim if an unfamiliar charge appears.

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

The main difference is where the money comes from when you pay.

With a credit card, the money comes from the bank. The bank gives you a limit, for example €1,500 per month, and you make purchases within that limit. At the end of the month or on the agreed date, the bank charges you. You can pay the full amount or spread it over instalments, and if you defer payment, you pay interest. For the bank to lend you that money, it needs to check that you can repay it, which is why it asks for income, history and checks your credit profile.

With a debit card, the money is yours and comes directly out of your bank account at the time of purchase. If you pay €40 at the supermarket, those €40 are instantly deducted from your account balance. There is no loan and no deferred charge. That is why a debit card is always linked to a bank account opened in your name.

With a prepaid card, there is no linked current account. You load the card with the amount you want and spend from that balance. When it runs out, you top it up again. You can top it up by bank transfer, with another card, with physical vouchers or, in the case of cards like Bitsa, also with crypto. Some prepaid cards come with an associated IBAN, which makes it possible to receive transfers directly onto the card without needing a bank account.

In practical terms: a credit card advances money, a debit card deducts money from your account, and a prepaid card spends a balance you have loaded yourself.

Advantages and disadvantages of each card

A credit card gives you breathing room. You can make a larger purchase without having the money in your account that day, split it into instalments and align the payment with when you get paid. It also often includes associated insurance, such as travel cover, purchase protection or assistance, which the other two types of card do not usually include by default. In return, deferred payment interest is high, there is often an annual fee, and the issuer can reject your application if your profile does not meet its criteria. The real risk is spending more than you can repay, because your monthly limit is not the same as your savings.

A debit card is the simplest to manage. You can only spend what is in your account, so you do not build up debt or pay interest. It is often included with a current account at no extra cost, is accepted in almost any shop and can be used to withdraw cash from ATMs. The downside is that you need a bank account in your name, the insurance included is usually minimal, and in online purchases the level of protection against a fraudulent charge depends heavily on the bank and the merchant.

A prepaid card is useful for separating spending from the rest of your money. You load a specific amount, spend from that balance and, if the card is cloned or a charge appears that you do not recognise, the maximum you risk is whatever was loaded at that moment. It does not require banking history, can be opened with a valid identity document (DNI, passport or NIE) and some, such as Bitsa, allow crypto top-ups as well as top-ups by bank transfer, card or voucher. The weak point is that virtual prepaid cards cannot be used to withdraw cash from ATMs, only the physical card can, and depending on the provider, there may be fees for topping up or withdrawing cash.

How each card protects you against fraud

All three types of card are subject to European payment regulations (PSD2), which require strong authentication for most online purchases. That is why you are asked to confirm with your phone or with a code. This applies equally to credit, debit and prepaid cards issued in the European Union. The real difference appears once a charge you do not recognise has already been made.

With a credit card, that unrecognised charge does not touch your current account. The money at stake belonged to the bank, so while the case is being investigated, your actual balance does not move. With a debit card, the amount does leave your account immediately and only comes back once the issuer resolves the claim. The law protects you in the same way, but you may be left without liquidity for a few days if the charge was high.

With a prepaid card, the maximum loss is the balance loaded at that moment. Nobody can pull money from a bank account because there is none linked. Most providers let you block the card from the app in seconds. On the other hand, prepaid cards do not usually include purchase insurance: if the problem is that the merchant does not send the order, the claim follows the general consumer route.

What to check before choosing a card

Before applying for a card, it is worth organising four things: what requirements you will need to meet, how much you will pay to have it, what you need to do with it and how much margin you want in case something unexpected happens.

• Requirements: A credit card requires income, history and approval from the bank. A debit card requires a current account in your name with that institution. A prepaid card can be opened with a valid identity document (DNI, passport or NIE) and without a solvency check, making it accessible for people without a bank account, people with irregular income or people who do not want to share their bank details with more platforms.
• Cost: Check the annual fee, ATM withdrawal fees, foreign currency fees and top-up fees if it is prepaid. With credit cards, pay close attention to the APR for deferred payments: that is where the real cost sits if you do not pay the full bill every month.
• Use: If you are going to make large purchases and pay them in instalments, a credit card makes sense. If it is your main card for everyday spending linked to your salary, a debit card fits. If you want a card with a separate balance (for online shopping, travel, specific expenses, giving to a minor, or if you get paid in crypto and want to spend it directly), a prepaid card with an IBAN like Bitsa fits that use case.
• Margin: If you are travelling or buying from merchants you do not know, consider which card you carry. Credit gives more purchase protection, debit gives less, prepaid limits the loss to the loaded balance. Many people combine two: a prepaid card for online spending and travel, and a debit or credit card for the rest.

Frequently asked questions

Can I have a card without having a bank account?
Yes. Prepaid cards are issued without needing to open a current account. They only require a valid identity document (DNI, passport or NIE) and identity verification (KYC). With a credit or debit card, that is not possible: both are linked to a banking institution.

Can a prepaid card be used to receive a salary or transfers?
It depends on the provider. Prepaid cards with an associated IBAN can receive transfers directly onto the card, much like an account. Those without an IBAN only work for payments and top-ups, but cannot receive external income.

Which card has lower fees when travelling outside the eurozone?
It depends on the issuer, not on the type of card. Some debit, credit and prepaid cards apply a foreign exchange fee, while others do not. Before travelling, check the fine print on fees for foreign currency transactions and ATM withdrawals outside the eurozone.

Can I withdraw cash from an ATM with a prepaid card?
Only with the physical card. Virtual prepaid cards cannot be used to withdraw cash under any circumstances. If you need ATM access, request the physical version from the provider you use.

What happens to the balance if I lose my prepaid card?
The balance is linked to your user account, not to the plastic card. You can block the card from the app and request a new one; the money remains available to spend with the replacement card.

Can I have more than one prepaid card at the same time?
Yes. Many providers allow several cards, virtual and physical, within the same account, with separate balances. This is useful for splitting spending (travel, subscriptions, online shopping) or for giving a card with a limited balance to another authorised person.
