A Simple Guide to Credit Cards
Credit cards are a convenient and versatile financial tool that can be used to make purchases, build credit, and earn rewards.

To make use of credit cards and not fall into debt, you need to understand the basics of credit cards and use them responsibly.
In this article, you will learn what credit cards are and how they work. Read the details before you make a decision to get a credit card.
What is a Credit Card?
A credit card is a payment card allowing the cardholder to borrow money from the issuing bank to make purchases. In the United States, credit cards are widely used for everyday transactions, as well as for larger purchases and emergencies.
To obtain a credit card, an individual must apply for one with a bank or other financial institution. The issuing institution will review the individual's credit history and income to determine their creditworthiness and decide to approve or deny the application. Once approved, the cardholder is given a credit limit, which is the maximum amount they can borrow from the bank.
How do Credit Cards Work?
When a cardholder makes purchases with a credit card, the bank covers the cost of the transaction. The cardholder is required to repay the amount borrowed, plus interest and fees, within a specified period. The interest rate and fees vary among credit cards and are determined by the issuing bank.
To get a credit card, an individual needs to apply for one with a bank, credit union, or other financial institution. The institution will assess the applicant's credit history, income, and other financial information to determine their creditworthiness. If the applicant is approved, the institution will issue them a credit card.
The credit card issuer will set a credit limit. It is the maximum amount of money the cardholder can borrow. This credit limit is based on the applicant's credit history and income.
The cardholder will receive a monthly statement that shows the amount borrowed, the interest charged, and the minimum payment due. The cardholder must pay the minimum payment by the due date, or they will incur late fees. The cardholder can pay the entire balance or make partial credit card payments and carry a balance from month to month.
The financial institution will charge interest on the outstanding balance if the cardholder does not pay the entire amount due each month. The interest rate can vary depending on the card and the cardholder's creditworthiness. The cardholder may also be charged annual fees, balance transfer fees, and other fees for using the card.
Many credit cards in the USA offer rewards and benefits to cardholders, such as cash back, points, miles, or discounts on purchases. Cardholders can earn these rewards by using the card to make purchases. The rewards and benefits can vary depending on the card and the card issuer.
The cardholder's credit card usage can affect their credit score, which is a measure of their creditworthiness. A credit score takes into account the cardholder's payment history, credit utilization, length of credit history, and other factors. A high credit score can help the cardholder get approved for loans, mortgages, and other financial products at better rates.
Types of Credit Cards
There are several types of credit cards, each with its own unique features, benefits, and disadvantages. Here are the most common types of credit cards:
- Rewards credit cards. These credit cards offer rewards for making purchases, such as cash back, points, miles, or discounts. The rewards program can vary depending on the card, but they generally allow cardholders to earn rewards for everyday purchases such as groceries, gas, and travel.
- Cash back credit cards. These credit cards offer cash back rewards on purchases. The cash back rate can vary depending on the card and the type of purchase. Some cards have a flat cash back rate on all purchases. Others offer higher cash back rates in specific categories, such as gas or groceries.
- Travel rewards credit cards. These credit card rewards are used for travel-related expenses, such as airfare, hotel stays, and rental cars. Cardholders can use the rewards to pay for their travel expenses or exchange them for other travel-related benefits, such as upgrades or discounts.
- Balance transfer credit cards. These credit cards are designed for individuals who carry a balance on one or more credit cards. Balance transfer credit cards typically offer a low introductory interest rate on balance transfers for a specified period of time, allowing cardholders to save money on interest charges.
- Secured credit cards. Compared to unsecured credit cards, these credit cards are designed for individuals who have limited or poor credit histories. Secured credit cards require a security deposit. It acts as collateral for the credit line. The credit line is typically equal to the security deposit, and the cardholder of a secured credit card is required to make regular payments to build their credit history.
- Student credit cards. These credit cards are designed for college students starting to build their credit history. Student credit cards have lower credit limits, but they offer benefits such as cash back rewards or low interest rates.
- Small business credit cards. These credit cards are designed for small business owners who need to make business-related purchases. Small business credit cards typically offer rewards and benefits specifically for businesses, such as earning rewards on business expenses, tracking expenses, and generating financial statements.
- Premium credit cards. These credit cards are designed for individuals with high credit scores and high incomes. Premium credit cards offer a range of luxury benefits, such as lounge access, travel insurance, and concierge services. These cards also have higher annual fees and interest rates.
Credit Cards vs. Debit Cards
Credit cards and debit cards are two of the most widely used payment methods. They have several key differences.
- Credit cards allow you to borrow from the issuer, while debit cards allow you to spend only the money you have in your linked checking bank account.
- Credit cards often come with interest charges and fees. These can be annual fees, balance transfer fees, and late payment fees. A debit card does not typically have them, but they may have other fees, such as overdraft fees, monthly maintenance fees, and foreign transaction fees.
- Many credit cards offer rewards programs. You can opt for cash back, points, miles, or discounts, for making purchases. Debit cards typically do not offer rewards programs, although some banks may offer cash back rewards or other benefits to their customers.
- Using a credit card responsibly and making on-time payments helps you build your credit history and improve your credit score. On the other hand, using a debit card does not help you build your credit history, as it does not involve borrowing money.
- Both credit cards and debit cards offer fraud protection. Credit cards typically offer zero liability for fraudulent purchases, meaning that you are not responsible for unauthorized charges on your card. Debit cards may also offer zero liability for fraudulent purchases, but if unauthorized charges are made before you report the fraud, the money may not be immediately available to you.
- Credit cards are widely accepted and are used to make purchases at millions of merchants, both online and in-person. A debit card can also be used to make purchases, but they may not be accepted at all merchants, especially those that do not accept electronic payments.
- Debit cards can be linked to overdraft protection. It allows you to spend more money than you have in your checking bank account without incurring overdraft fees. Credit cards do not offer overdraft protection.
Pros and Cons of Credit Cards
Pros
- Convenience. Credit cards are widely accepted and can be used at millions of merchants, both online and in-person. They are a convenient and secure way to pay for goods and services, especially for those who travel frequently or who do not want to carry cash.
- Rewards. Many credit cards offer rewards programs, such as cash back, points, miles, or discounts, for making purchases. These rewards can provide significant benefits, such as travel, merchandise, or cash.
- Credit building. If you use a credit card responsibly, make on-time payments, and keep a low balance, you build your credit history and improve your credit score. A good credit score allows you to get approved for loans, mortgages, and other financial products with lower interest rates.
- Fraud protection. Credit cards often offer fraud protection. You will not be responsible for unauthorized charges on your card. In case your card is lost or stolen, or if someone makes unauthorized charges, you can report the fraud and get your money back.
- Emergency funds. Credit cards can provide a source of emergency funds in case of unexpected expenses, such as medical bills, car repairs, or home emergencies. However, high-interest credit card debt can quickly spiral out of control.
Cons
- High interest rates. Credit cards often come with high interest rates, especially if you carry a balance from month to month. The interest charges can quickly add up, making it difficult to pay off your debt and leaving you with less money to spend on other things.
- Fees. Credit cards often come with fees, such as annual fees, balance transfer fees, and late payment fees. These fees can add up, making it even more difficult to pay off your debt.
- The temptation to overspend. Credit cards can make it easy to overspend, as you may feel like you have more money than you actually do. This can lead to high levels of debt and financial stress, especially if you are unable to pay off your balance each month.
- Impact on credit score. If you miss payments, carry high balances, or max out your credit card, it can have a negative impact on your credit score. This can make it difficult to get approved for loans, mortgages, and other credit products in the future.
