What Is a Debit Card: A Complete Guide to How It Works and How to Use It

A debit card is a payment instrument that combines the functions of a traditional ATM card with the capabilities of a credit card, but with a fundamentally different working mechanism. If you have a debit card in your wallet, you might have never stopped to think about how that card actually works. Essentially, what is a debit card? A debit card is a tool issued by your bank to access funds that you have already deposited in your bank account.

Unlike a credit card that extends a line of credit, a debit card is directly linked to your bank account. When you make a transaction using a debit card, the bank immediately deducts the money from your balance. You can use a debit card to shop online, at store checkout counters, or even through digital wallet apps to pay, without needing to write a check.

Understanding the Basic Functions of a Debit Card

A debit card is issued by your bank or financial institution and functions as a combination of an ATM card and a digital payment card. However, there is a critical difference that sets it apart from a credit card: a debit card uses the money already in your bank account, not money borrowed with a promise to pay later.

Every debit card you use is a safe and convenient tool to access your funds anytime. With the increasing number of users across Southeast Asia, debit cards have become the preferred payment method for millions of consumers seeking ease without debt complications.

How Debit Cards Work in Daily Transactions

When you use a debit card to pay, several important steps happen behind the scenes. The debit card partners with major credit card brands like VISA, Mastercard, and Discover to allow you to pay wherever those brands are accepted.

In in-store transactions, you will swipe, insert, or use contactless payment at the checkout terminal, just like with a credit card. Then, you will enter your Personal Identification Number (PIN) into the machine, although some merchants allow PINless transactions.

Your PIN is a security measure that verifies your identity. Once the bank verifies that you have sufficient funds to make the purchase, your transaction is approved. In your bank statement, you might see the purchase marked as “pending,” meaning the bank has not yet transferred the money to the merchant even though your account has been debited. When the bank sends the money to the merchant, your transaction will show as “approved.”

What makes a debit card unique is that you can complete the transaction because you already have the necessary funds in your linked account. Depending on your bank’s policies, you may be allowed to go over your account balance up to a certain amount if you have additional funds available in a backup account, such as a savings account.

Types of Debit Cards Available

What are the different forms of debit cards? There are four main types of debit cards, and the key differences among these types generally lie in the issuing entity:

Standard Debit Card

The most common type issued by your bank or credit union, linked to your checking or money market account. These cards typically carry the VISA, Mastercard, or Discover logo and can be used for in-person or online purchases. You can also use this type of card to make deposits and withdrawals at your network’s ATMs.

ATM Card

Similar to a standard debit card, ATM cards are issued by your bank and linked to a specific bank account. However, these cards are only used for cash withdrawals or, in some cases, deposits at ATMs. ATM cards cannot be used for online or in-store shopping.

Prepaid Debit Card

Prepaid debit cards are linked to a bank account you own but are not issued directly by the bank. Instead, these cards must be loaded with funds before they can be used. Most can be used similarly to regular debit cards, but some may have fees for various services. Online services like Netspend and retailers like Walmart offer their own branded prepaid debit cards, as do major credit card companies like VISA, Mastercard, and American Express.

Electronic Benefit Transfer (EBT) Card

A government-issued debit card designed to provide social benefits to cardholders. Programs like food assistance pay their benefits monthly onto the card balance. Cardholders can then use the card to pay for approved purchases at merchants accepting EBT cards.

How to Get a Debit Card

Financial institutions often issue debit cards automatically when you open a checking account, but you may need to request one explicitly. After receiving the card, you will activate it according to the included instructions. During activation, you will set your own PIN, which you will use for in-store purchases, cash withdrawals, and ATM transactions.

If you do not have a bank account, you can obtain a prepaid debit card through various online services or at major retailers. Keep in mind that some prepaid cards charge monthly maintenance fees that can reduce your available funds.

Minimum Age to Obtain a Debit Card

It’s important to note that each bank sets a minimum age requirement for their debit cards. However, depending on the bank and account type, there are options to issue debit cards to those as young as 13 years old. These accounts are typically labeled as teen checking accounts and require a parent or guardian as a joint account holder. Once someone turns 18, they legally have the right to open a bank account in their own name without a joint holder.

Pros and Cons of Using a Debit Card

Before deciding if a debit card is the right financial tool for you, it’s important to understand its advantages and disadvantages.

Advantages of Debit Cards

No Annual Fees

Unlike some credit cards, debit cards issued by your bank or credit union are free of annual fees. This makes debit cards a cost-effective choice for long-term use.

Convenience and Ease of Use

Debit cards can be used at millions of stores, online merchants, and ATMs worldwide. They can even be added to digital wallets, providing maximum flexibility in how you pay.

Helps with Budget Management

Instead of running a credit card balance, a debit card allows you to pay with the cash already in your account. This helps prevent overspending beyond your planned budget.

Disadvantages of Debit Cards

Not Completely Fee-Free

Prepaid debit cards often have monthly maintenance fees. If you exceed your balance, your bank may charge overdraft or insufficient funds fees. Also, be aware of ATM fees if you use out-of-network ATMs.

Better for Small Purchases

Debit cards are great for routine expenses like groceries, but large purchases like a flat-screen TV might deplete most of your account balance at once.

Potential for Impulsive Spending

The ease of using a debit card can encourage transactions without careful consideration of your available funds, risking your carefully planned budget.

Fees and Usage Limits for Debit Cards

While debit cards generally do not have usage fees for everyday transactions, there are some situations where fees may apply:

Overdraft Fees

If you make a purchase that exceeds your account balance, you may be charged an overdraft fee.

ATM Fees

Many banks do not charge for ATM withdrawals within their network. If you use an out-of-network ATM, you will be notified of any applicable fees before completing the transaction.

Account Holds

When using your debit card to reserve a hotel room or rent a car, a hold may be placed on your account for an amount greater than your transaction. This hold reduces your available balance until it is released.

Comparing: Debit Card vs Credit Card vs Prepaid Card

Understanding the differences among various payment cards is key to making sound financial decisions.

Debit Card vs Credit Card

Debit cards differ from credit cards in several important ways. Credit cards extend a line of credit available for purchases. You can pay back the used credit line over time with monthly payments. Credit card companies charge interest on your balance as compensation for taking on the risk of your purchases.

In contrast, a debit card is not a line of credit. It uses the money you already have in your bank account to pay merchants for goods and services or to withdraw cash from ATMs.

Prepaid Card vs Traditional Debit Card

Two types of cards with similar names can confuse some consumers:

• Traditional debit cards are issued by your bank and directly linked to your checking account, using your deposited funds for ATM withdrawals and purchases.
• Prepaid debit cards, also called prepaid cards, require you to load funds onto the card before use (similar to buying a gift card). You can add funds via cash, electronic transfer, or check. You can load funds online or at retailers supporting prepaid cards.

ATM Card vs Debit Card

Although both allow access to your checking account funds, ATM cards cannot be used for purchases. Their use is limited strictly to ATM transactions.

Handling Lost or Stolen Debit Cards

If your debit card is lost or stolen, don’t panic. Lost and stolen cards happen every day. Contact your bank immediately and inform them of what happened. Some banks allow you to report this online through their online banking portal, while others require a phone call.

Sometimes, the bank will freeze your card if you find it later. Other times, they will deactivate the current card and send you a new one.

If your card is lost or stolen, it’s crucial to report it quickly to minimize your liability for unauthorized charges. If you report the loss or theft within two days, your maximum liability is $50 for unauthorized charges (and some banks waive this fee as a courtesy). Your liability increases to $500 if you do not report the loss until after two days but within 60 days of the statement date.
