What's a debit card? Everything you need to know

Managing your daily finances should be simple and easy. For most people in the UK, a debit card is the primary tool for paying for shopping, withdrawing cash, and sticking to a budget in real-time. With the right card, you can keep track of your money without the worry of monthly billing surprises or interest charges.

At Revolut, our cards are linked to your personal account and allow you to manage, withdraw, and spend money in the UK and abroad.

Debit cards at a glance: key things to consider

A debit card is a tool for spending your own money directly from your account balance. Before you choose a card, here are the core points you should know about how they work in the UK:

• Account deduction: every payment is taken from your account balance, generally instantly.
• Budget control: you can only spend what you have in your account, which helps you avoid debt.
• No interest: unlike credit cards, there are no monthly statements that incur interest rates for late payments.
• Worldwide acceptance: modern debit cards from Visa or Mastercard are accepted at millions of locations globally and online.
• Revolut cards: our cards can do all of the above. Additionally, with Revolut, you can have disposable virtual cards alongside your regular ones, adding another layer of protection for your spending.

What's a debit card?

A debit card is a payment card that deducts money directly from your account balance when you make a purchase. The term 'debit' refers to the fact that the bank takes away the specific amount from your available money. Unlike credit cards, there isn't a monthly bill to pay off later. Instead, your balance updates in real-time.

In the UK, debit cards are the standard for everyday banking. While older generations might remember brands like Switch or Maestro, modern UK banking relies almost entirely on Visa and Mastercard. These cards follow the international ISO/IEC 7810 standard, which means they work at almost any card terminal or online checkout in the world.

A key feature of a modern debit card is the 16-digit card number, the expiry date, and the 3-digit security code (CVV) on the back. These details allow you to use your card for online shopping, subscriptions, and adding your card to digital wallets like Apple Wallet or Google Wallet.

Revolut debit cards

Our cards are either Visa or Mastercard, which are both accepted globally. They can be used to pay online or in-store, as well as via digital wallets. You can also use them to withdraw cash from ATMs worldwide, with no-fee withdrawal limits on each plan. Third-party ATMs may still charge fees, but you can locate our in-network ATMs in-app to avoid these surcharges.

With us, you also benefit from advanced Revolut security features from the palm of your hands, such as freezing and unfreezing your card in-app in seconds.

We allow our customers to create up to 20 virtual cards for free.

How to tell if you have a debit card

You can tell if you have a debit card by looking for the word Debit printed on the plastic. Most modern UK cards clearly state their type to avoid confusion at the checkout.

How does a debit card work?

When you pay at checkout, the card reader communicates with your bank to verify you have enough money. Once the bank confirms the money is available, the transaction is authorised. In the UK, this process usually takes less than a second.

Most UK debit cards support contactless technology. For purchases up to £100, you don't usually need to enter your PIN. You can simply tap your card or smartphone against the reader. For higher amounts, or occasionally for security checks, you'll be asked to insert your card and enter your 4-digit PIN.

Debit card vs credit card: the key differences

The main difference between a debit card and a credit card is whose money you're spending. While they look similar and are both accepted globally, they function very differently behind the scenes.

How credit and debit cards work

With a credit card, the bank provides you with a credit limit. You spend the bank's money throughout the month and receive a statement at the end. If you don't pay the full balance back, you'll be charged interest. This can provide flexibility but requires discipline to avoid debt.

A debit card uses your own money. There's no credit involved, and your banking app balance is always accurate. If you want to stick to a strict budget, a debit card's usually the safer and simpler choice.

Advantages and risks of debit cards

Using a debit card is a balance of convenience and responsibility. Understanding these factors helps you use your card more effectively.

Real-time financial transparency

The advantage is clarity. Since every payment is charged immediately, you won't face any surprises at the end of the month.

With our card you get instant push notifications for every transaction, so you always know exactly where your money's going. You can even use our budget planner to categorise your spending automatically.

Security and online shopping with Revolut cards

Modern debit cards are equipped with high security standards like 3D Secure (often called 'Verified by Visa' or 'Mastercard ID Check').

With Revolut, if you lose your card, you can block it instantly in-app. Using disposable virtual cards is another way to spend money online without exposing your main card’s details.

Potential hurdles with deposits

Some car hire companies and hotels require a credit card for security deposits. They prefer credit cards because they can place a hold on a credit line without actually taking the money.

With a debit card, that money would be blocked from your balance, which some providers refuse to do. It's always best to check with your provider before you travel.

Getting a card for free

With Revolut, you can open a Standard plan account, which carries no monthly maintenance fees. Your first physical card is free, though delivery fees may apply. You can also create virtual cards for free, making them a great way to start spending money right away without extra costs.

Even younger family members can get involved. With Revolut Kids & Teens, kids from 6–15 years old can have an account with a card, supervised by parents. And teens from 16–17 can have their own personal account with a teens card.

T&Cs apply. Kids & Teens accounts are available for ages 6–15, and the parent or guardian must be 18+ and have a Revolut account.

Teens aged 13+ can create an account with parent or guardian permission. Payments to and from other customers on Revolut Kids & Teens are only available to teens aged 13+.

Some products and features are only available for kids above a certain age. See availability in-app.

FAQs about debit cards

Can I pay online with a debit card?

Yes, you can. Modern Visa and Mastercard debit cards have all the details needed for online shopping, including the 16-digit number and CVV code.

Will my credit score be checked?

Generally, no. Because a debit card uses your own money rather than a credit line, a hard credit check isn't usually required to issue the card. This makes debit cards accessible to more people, regardless of their credit history.

What happens if I don't have enough money?

Usually, the transaction will simply be declined if your balance is too low. This prevents you from spending money you don't have and allows you to avoid the high interest rates associated with unauthorised overdrafts.
