Credit Cards vs. Debit Cards: What’s the Difference and Which One Should You Use?
In today’s digital age, cashless payments have become an essential part of everyday life. Two of the most common payment tools are credit cards and debit cards. While they might look the same and are both used to make purchases, their nature and how they work are actually quite different.
This article will break down the key differences between the two, so you can choose the one that best fits your financial needs.
What Are Debit Cards and Credit Cards?
To clearly understand the differences, let’s first get familiar with the basic concepts of these two types of bank cards.
What is a Debit Card?
A debit card is a payment card directly linked to your bank account. It works on a simple principle: "You spend what you have." This means you can only use the money available in your account balance. When you make a purchase, the amount is deducted immediately from your account.
Basically, a debit card acts like a digital wallet, giving you easy access to your own money without needing to carry cash.
Nowadays, debit cards are mainly divided into two types:
- Domestic debit cards: Can only be used for transactions within Vietnam.
- International debit cards: (Usually with Visa or Mastercard logos) allow you to make payments both inside and outside the country.
The main functions of a debit card include withdrawing cash from ATMs, transferring money, and paying bills or services at stores (via POS machines) or online platforms.
What is a Credit Card?
A credit card works on the principle of “Spend now, pay later.” Essentially, the bank gives you a credit limit (a loan amount) that you can use for shopping and other expenses. You can spend up to that limit and then repay the bank by the end of your billing cycle.
Like debit cards, credit cards come in two common types: domestic credit cards and international credit cards (such as Visa, Mastercard, or JCB). The main features include making payments online and in-store, cash withdrawals (usually with higher fees), and especially the option to buy on installment plans with attractive interest rates, sometimes even 0%.
Detailed Differences Between Credit Cards and Debit Cards
The core difference between these two types of cards lies in the source of the money used, which leads to differences in eligibility requirements, costs, and functions.

| Key Features | Spend first, pay later. You’re using the bank’s money. | Load money first, spend later. You’re using your own money. |
| Source of Funds | Credit limit provided by the bank. | Money available in the cardholder’s bank account. |

| Annual Fees | Usually higher (can range from a few hundred thousand to several million VND). Cash withdrawal fees are very high (around 4% of the withdrawn amount). | Usually lower or sometimes free. ATM withdrawal fees within the same network are low or free; for other networks, fees range from about 3,000 to 10,000 VND. |
| Interest Rates | Interest rates apply (around 20-40% per year) if you don’t pay off your full balance on time. Interest also applies immediately when you withdraw cash. | No interest because you are spending your own money. |
| Impact on Credit Score | Your credit card usage history directly affects your CIC credit score. Paying on time helps improve your credit score. | Does not affect your credit score. |
Comparing the Pros and Cons of Debit and Credit Cards
Each type of card has its own strengths and limitations. Understanding these factors will help you choose the one that best suits your needs.
| Credit Card | Debit Card |
| Advantages |
- Flexible finances: Helps cover urgent expenses even when you don’t have cash on hand.
- Attractive perks: Enjoy cashback, discounts, and 0% installment plans that help you save money.
- Build credit history: Responsible spending and on-time payments help improve your credit score, useful for future loans.
- More secure if lost or stolen: If your card is lost, you can report and lock it immediately. You won’t be held responsible for any fraudulent transactions after that.
|
- Easy to manage spending: You can only spend what you already have, which helps prevent overspending and debt.
- Simple to open: The application process is easy, and most people can get one without strict requirements.
- Low usage costs: Annual fees and transaction fees (like ATM withdrawals) are usually much lower than those of credit cards.
- Great for everyday use: Perfect for basic needs like withdrawing cash and transferring money.
|
| Disadvantages |
- Risk of debt: Without careful spending and timely payments, you could face high interest charges and late fees.
- High fees and interest rates: Annual fees, cash withdrawal fees, and overdue interest rates can be quite expensive.
- Stricter application requirements: You’ll need to prove your income and have a good credit history to get approved.
|
- Limited by your account balance: You can’t spend more than what’s in your account, which makes it less flexible in emergencies.
- Fewer perks: Promotional offers and discounts are usually less attractive and less varied compared to credit cards.
- Higher risk if lost or stolen: Since the card is directly linked to your bank account, if someone gets your card details, your entire account balance could be at risk.

Should You Get a Credit Card or a Debit Card?
The answer depends entirely on your personal needs, spending habits, and ability to manage your finances.
1. You should consider a debit card if:
- You want a simple payment tool to replace cash for everyday expenses like dining, shopping, and paying bills.
- You prefer to keep tight control over your spending and only spend within your set budget.
- Your income is not yet stable, or you don’t want to go through complex financial verification processes.
- You’re a student or someone new to managing personal finances and want to start building good money habits.
2. You should consider a credit card if:
- You have a stable income and good financial discipline to ensure timely repayments.
- You often make big purchases (like electronics, flight tickets, or hotel bookings) and want to take advantage of 0% installment plans.
- You want to benefit from exclusive perks like cashback, discounts, or airline miles to make your spending more rewarding.
- You need a backup financial option for emergencies.
- You’re planning to build a strong credit history to support bigger financial goals in the future.
In fact, many savvy consumers choose to own both types of cards. They use debit cards for everyday expenses and ATM withdrawals, while credit cards are reserved for larger transactions, online shopping, and taking advantage of special offers.
This combination allows them to manage spending efficiently while still enjoying the full range of financial benefits credit cards can offer.
Frequently Asked Questions about Credit Cards
1. Can I have both a debit card and a credit card at the same time?
Absolutely! Having both cards actually gives you the best of both worlds. Each card type has its own advantages, and using them together can help you manage your finances more flexibly and effectively. They're not mutually exclusive, instead, they complement each other quite well.
2. Is a credit card safer than a debit card?
Both types of cards are equipped with advanced security features like EMV chips, PIN codes, and 3D-Secure authentication. However, credit cards usually offer a bit more protection when it comes to fraud. That’s because if someone makes unauthorized charges on your credit card, they’re spending the bank’s money, not yours. You’ll have time to dispute the charges, and the bank will investigate without directly affecting the balance in your personal account.
On the other hand, with a debit card, the money is taken directly from your account. If fraud occurs, recovering those funds can be more complicated and take longer.
Credit cards and debit cards are both modern, convenient payment tools. By understanding how each one works along with their pros and cons you can choose the option that best fits your financial goals and lifestyle.
