Debit vs. credit cards—know the difference

Cashless cards may all look similar, but the way they work is completely different. Discover the differences between debit, credit, and pre-paid cards with this simple guide.

What is a debit card?

Debit cards are linked to your bank account, giving you access to your balance. You can use them to make purchases in stores or online, or withdraw from ATMs. They’re easy to use and mean you don’t need to carry physical cash. In some cases, you can borrow money from a debit account using overdraft, which allows your balance to go into the negatives. But there are often extra charges for this, especially if you haven’t arranged it in advance with your bank.

What is a credit card?

Credit cards borrow money from the card issuer every time you make a purchase. Each payment you make gets added to your total outstanding balance, which you’ll have to pay back later, along with any interest required. Credit cards offer lots of advantages, like quick access to funds, building your credit rating, cashback rewards, fraud protection and more. But they can also be risky—if you aren’t able to pay back your outstanding balance, your credit score will drop and the interest can add up.

What is a pre-paid card?

Pre-paid (or top-up) cards work as a fixed payment system—you load money onto the card from another account or with cash. This amount isn’t linked to your bank account, so you never have to worry about overspending. They’re great for setting budgets or cutting down on carrying cash. Plus, they’re usually reloadable, and you generally don’t need a credit check to get one. However, they can include multiple fees so make sure you read the fine print.

Debit vs. credit vs. prepaid cards

Now that you know the basic differences between debit, credit, and pre-paid cards, decide which option is right for you.
  • Debit cards generally offer easier terms of eligibility and minimize debt risk. Plus, you get the option of saving money in your own bank account.
  • Credit cards offer extra spending flexibility, but there’s a risk if you can’t pay the money back right away.
  • Pre-paid cards will prevent you from going into debt, but you won’t have the flexibility of a full bank account

    A credit card is a payment card that allows the cardholder to borrow funds from the lender. This line of credit is a loan between the lender and holder, typically paid back monthly.

    A debit card is a payment card that acts as a direct link to the cardholder’s bank account. When the cardholder makes a purchase, the money is taken straight out of the cardholder’s current balance.

    A pre-paid debit card or top-up card is a payment card that allows the cardholder to top-up a set amount of money onto the card. It is generally not connected to a bank account or line of credit, and thus the cardholder cannot spend beyond the amount of money they’ve topped up onto the card.

    All Apex Unity bank cards are debit Mastercard cards with contactless NFC technology. Credit cards are not currently offered.
