Understanding Credit Union Credit Cards vs. Debit Cards: iQ Credit Union's Comprehensive Guide

iStock-1326655860It's important to understand the differences between credit and debit cards, how they work, and when to use them in today's financial landscape. By understanding their features, fees, benefits, and best practices, you can make informed decisions that will help you manage your finances effectively. Let's dive in!

How do credit cards and debit cards work?

We want to make sure our members understand how credit cards and debit cards work. A credit card lets you buy things on credit, borrowing money from the issuer and paying it back later. Credit cards offer flexibility and convenience because of their credit limits, interest rates, and rewards. 

On the other hand, debit cards are directly linked to your checking account, enabling you to spend the funds you already have. Understanding the ins and outs of these cards can help you make smart financial decisions.

Credit Cards

Credit cards are financial tools that allow you to make purchases on credit. When you use a credit card, you're essentially borrowing money from the card issuer, which you will need to pay back later. Each credit card comes with a credit limit, which is the maximum amount you can borrow. Interest is charged on any unpaid balance, and credit cards can have different rates for purchases, balance transfers, and cash advances.

Debit Cards

Debit cards are linked directly to your checking account. When you use a debit card, the funds are withdrawn directly from your account to cover the transaction amount. It's important to note that debit cards typically don’t involve borrowing money because you are using the funds you already have in your account. Overdraft protection is a service provided by financial institutions—usually for a fee—to prevent your account balance from falling below zero.

What are the key differences between credit cards vs. debit cards?

We want to help you navigate the key differences between credit and debit cards so you can make informed decisions about your financial choices. 

Credit Score Impact

There's one important difference: how they affect your credit score. When you use them responsibly, credit cards can positively impact your credit score. A good credit history can help you get better interest rates and financial opportunities by making on-time payments and keeping your credit utilization low. Because debit cards are tied to checking accounts, they're not directly linked to credit scores.


It's also important to know the fees associated with credit and debit cards. Credit card fees include annual fees, balance transfer fees, and late payment fees. Choosing a credit card that aligns with your financial goals is key to avoiding or minimizing these costs. With our low- or no-annual-fee credit cards, you can maximize your benefits.

Despite debit cards having fewer fees, you still need to watch out for them. Checking account maintenance fees and ATM fees are common examples. iQ and other credit unions offer credit cards with waived fees or rewards if you keep a minimum balance. Keeping an eye on your account balance and transactions will help you avoid any unexpected fees.

When should you use a credit card instead of a debit card?

Sometimes, it's hard to choose between a credit card and a debit card. Our goal is to give you helpful insights so you can make the right decision. Credit cards can come in handy in several situations: 

Paying for Large Expenses

Credit cards offer additional purchasing power, making them a great option for large expenses. Whether you're making a major home improvement or planning a dream vacation, having a credit card can provide the convenience and flexibility you need to cover these significant costs. Additionally, certain credit cards offer rewards programs that allow you to earn points or cash back on your purchases, providing you with added value and potential savings.

Building and Improving Credit

Another benefit of using a credit card is the opportunity to build and improve your credit history. You can establish a positive credit history by using your credit card responsibly, making timely payments, and keeping your credit utilization low. This can be beneficial when applying for loans, mortgages, or other financial opportunities in the future. It's a step toward financial stability and unlocking better interest rates and terms.

Traveling and Online Shopping

In addition, credit cards offer enhanced protection for travel and online shopping. When you're traveling, credit cards offer added security against fraudulent transactions, giving you peace of mind. Debit cards are protected too, not just credit cards. Credit cards may even offer travel insurance or rewards specifically for travel expenses, making them perfect travel companions.

What are the benefits of having a debit card?

Debit cards have a lot of advantages over credit cards—despite the allure of rewards and credit-building features. Debit cards encourage responsible spending since you use your own money, not borrowed money. Besides preventing debt, they also help with budgeting and spending control. Using cash instead of credit cards means you don't accrue interest charges on unpaid balances, which can often happen with credit cards.

Plus, a debit card makes it easy to get cash. Whether you need fast cash or your bank is closed, you can withdraw cash from ATMs without paying fees thanks to bank agreements with ATM networks. When you combine this with direct deposit and banking services that go with the checking account, you've got a fast, convenient way to get paid. Online or mobile banking apps let you pay bills, deposit checks, and transfer money.
