What is a debit card, and how do I get one?

Debit cards can unlock many of the benefits of your checking account.

October 28, 2025

If you’re taking your first steps toward financial independence, it’s the perfect time to get acquainted with the debit card. So let’s dive into what a debit card is, how to use a debit card, and how to get a debit card for yourself.

What is a debit card?

A debit card is a physical form of payment—meaning it’s a card you can hold in your hand—typically connected to a checking account. It’s possible to link a debit card to a money market account, a savings account, or another cash account, but linking it to a checking account is the most common. You can use a debit card to pay for things in person and online or to withdraw cash directly from your account via an ATM. Whether you’re making a purchase or withdrawing cash with your debit card, the money is immediately drawn (that is, debited) from your account.

What’s the difference between a debit card and a credit card?

Debit cards and credit cards look similar, but there are some important differences between debit cards and credit cards that you should keep in mind:

Where does the money on a debit card come from?

A debit card pays for transactions with money you already have in an account, while a credit card effectively picks up the tab and sends you a bill later. After buying something with your debit card, your account balance will decrease by the amount you just paid almost immediately. With a credit card, your credit balance is how much you’ll eventually need to pay back to the credit card company, while your available credit is how much you have left to spend before you reach your credit limit. When you purchase something with your credit card, your credit balance will increase by that amount, and your remaining available credit will decrease in tandem.

Spending limits on debit cards

With a debit card, you can only spend as much as you have in your account. Credit cards, by contrast, are effectively lending you money to spend. Credit card companies don’t want you to spend more than you can eventually pay back, so they cap how much money you can spend. This is known as your credit limit.

Costs and fees on debit cards

The most common fees associated with a debit card are minimum balance fees (when your balance falls below a required amount) and overdraft fees (when you don’t have enough money in your account to pay for your debit card transactions). Credit cards don’t have those fees, but you can incur other fees if you don’t pay your total monthly credit balance on time each month. That’s because you’ll start accumulating interest on any balances not paid in full by the end of the billing cycle. The longer it takes to pay off your balance, the more you’ll end up owing in interest.

Do money market accounts have debit cards?

Some, but not all, money market accounts offer debit cards. Money market accounts typically earn interest and are Federal Deposit Insurance Corporation (FDIC)-insured, but they can also offer some of the features of a checking account.

How does a debit card work?

Debit cards are versatile and are a convenient way to spend money without carrying a checkbook or large amounts of cash. When you know how to use a debit card, you can get the most out of:

ATM withdrawals

Debit cards can be used at ATMs to withdraw cash from your account. Simply insert or tap the card, type in your PIN, and select how much money you want to withdraw. Some banks and ATMs may charge fees if you use your card with an unaffiliated financial institution, so make sure you know which ATMs are free for you to use. There are more than 70,000 fee-free Capital One and partner ATMs located across the country.²

In-person transactions

Like a credit card, you can use your debit card in person at a cash register. Depending on your card type, you will either swipe, insert, or tap your debit card and enter your PIN to make your purchase. It’s quick and simple to pay for your groceries or coffee by just tapping your Capital One contactless debit card at the register.^3,4 You’re probably used to seeing debit cards used this way at stores and restaurants.

Online purchases

Debit cards can also be used for buying things online. However, when you place an order online, you typically need to enter more information since you can’t swipe your card. That information can include your card number, expiration date, security code, billing address, and possibly other verification information.

What are the benefits of a debit card?

There’s a reason that a debit card is a staple in so many people’s wallets. Debit cards come with several benefits:

Convenience. It’s a lot easier to use a debit card to buy things and withdraw money than it is to write checks.

Security. Your money is typically protected by FDIC insurance. (Check with your bank.) And many banks will send you a fraud alert if any suspicious activity is detected.

You can use a debit card to pay for things in person and online or withdraw cash directly from your account via ATMs, fees may apply.

What are typical debit card fees?

You won’t pay interest on the transactions you make with your debit card, but you need to be aware of common debit card fees and how to avoid them:

Overdraft fees. If your bank doesn’t offer overdraft protection, this is a fee to keep an eye on. That’s because if you accidentally spend more money than you have in your linked account, your bank may charge you an overdraft fee. You shouldn’t have to pay overdraft fees, and with Capital One 360 Checking, you don’t.¹
ATM fees. Using ATMs outside of your bank’s ATM network may result in transaction fees that will be deducted from your linked account. Capital One teamed up with MoneyPass and Allpoint to give you more ways to get cash. That means 70,000+ fee-free locations are ready when you are.²
Maintenance fees. Some banks charge account maintenance fees if your minimum balance falls below a certain amount. According to a 2024 Bankrate study, the average monthly maintenance fee for noninterest-earning checking accounts that charge this fee was $5.47. Capital One accounts are fee-free: Add in no minimum balance requirements and you have more money in your wallet.

While the above debit card fees can dwindle your account balance, they can often be avoided by checking your balance, keeping an eye on your spending, and using the right ATMs.

How do you get a debit card?

To get a debit card for yourself, follow these steps:

1. Research financial institutions
There are a lot of banks with different fees, ATM networks, and other benefits, so be sure to assess your options. Some banks may offer certain perks for opening a new account or using your debit card regularly, while others may have more flexible options that allow you to avoid fees.
2. Open an account with your financial institution of choice
Regardless of where you open it, you can’t have a debit card without some sort of bank account—such as a checking or a money market account—tied to your debit card. Once you’ve chosen a bank, open a checking account or money market account with them.
3. Activate your debit card
When you receive your card, it should come with instructions on how to activate it. This typically involves calling a phone number or going online. It’s easy to activate your new debit card right in the Capital One mobile app so you can start using it immediately.^3,4

How old do you have to be to get a debit card?

You can usually be any age to have and use a debit card, but if you’re under 18, you’ll need a legal guardian to open the linked account for you. There are no fees to open, keep or use your MONEY Teen Checking debit card, helping your kids keep more of their own money.^4,5

¹No-fee overdraft authorizes us to consider paying your checks, ACH and recurring debit transactions that put your account into overdraft. You also have the option to ask us to consider paying your everyday debit card and ATM transactions if they would cause you to overdraft your account. In making a payment decision, we typically consider a variety of factors, including the size of the transaction, whether your account is in good standing and/or if you have had too many overdrafts. If we elect to pay an overdraft item, you have no right to defer payment and you must deposit additional funds into your account promptly in an amount sufficient to cover the overdraft. To qualify for no-fee overdraft, you must regularly deposit at least $250 during two of the previous three calendar months. Accounts that haven’t met this will no longer have access to overdraft until the next month when you’ve met this requirement. New accounts will not have access to no-fee overdraft until the consistent deposit requirement has been met.
