What is Credit Card?

A credit card allows cardholders to make purchases online and in shops using credit. Financial institutions issue credit cards based on applicants’ credit history, job position, and other criteria. Cardholders can spend up to a certain limit set by the financial issuer, which takes into consideration factors such as credit history, income, and more.

Different Types of Credit Cards

Rewards Credit Cards:

Rewards credit cards are designed to provide cardholders with various incentives for their spending. These cards typically offer cashback, travel rewards, or points that can be redeemed for merchandise, gift cards, or experiences. By using a rewards credit card for everyday expenses, you can earn valuable rewards and enjoy perks like airline miles, hotel discounts, or even statement credits.

Travel Credit Cards:

For frequent travelers, travel credit cards are a popular choice. These cards often come with benefits like airport lounge access, travel insurance, and priority boarding. Additionally, they offer rewards specifically tailored for travel expenses, such as bonus points for flights, hotel stays, or dining abroad. Many travel credit cards also waive foreign transaction fees, making them a convenient and cost-effective option for international travelers.

Cashback Credit Cards:

Cashback credit cards provide a percentage of your purchases back to you as a cash reward. This type of credit card is ideal for individuals who prefer immediate financial benefits. Cashback rates may vary depending on the spending category, such as groceries, gas stations, or dining out. Some cashback credit cards offer higher rates for specific categories or rotating quarterly promotions. By strategically using cashback credit cards for everyday expenses, you can accumulate significant savings over time.

Balance Transfer Credit Cards:

If you have existing credit card debt, balance transfer credit cards can be an effective way to manage and reduce your debt. These cards allow you to transfer balances from higher-interest cards onto a new card with a lower or even 0% introductory interest rate for a specific period. By taking advantage of the low or no interest period, you can consolidate your debt and save money on interest payments, allowing you to pay off the principal amount faster.

Secured Credit Cards:

Secured credit cards are an excellent option for individuals looking to establish or rebuild their credit. These cards require a security deposit that serves as collateral against the credit limit. By responsibly using a secured credit card and making timely payments, you can demonstrate creditworthiness and improve your credit score over time. Many secured credit cards can be upgraded to unsecured cards after a period of responsible use.

How Does a Credit Card Work?

Credit cards function as a convenient and widely accepted payment method that allows cardholders to make purchases and access credit provided by a financial institution. Here’s how credit cards work:

Application and Approval:

To obtain a credit card, you typically need to apply with a bank, credit union, or financial institution. The application process involves providing personal information, such as your name, address, income, and employment details. The issuer evaluates your creditworthiness by reviewing your credit history, income, and other factors. Based on this assessment, they decide whether to approve your application and determine your credit limit.

Credit Limit:

Once approved, you are assigned a credit limit, which represents the maximum amount you can borrow using the credit card. The credit limit is determined based on factors like your credit history, income, and the issuer’s policies. It’s important to note that exceeding your credit limit may result in penalties and fees.

Card Activation:

Once you receive your credit card in the mail, you usually need to activate it before you can use it. This process typically involves calling a designated phone number or activating the card online, following the issuer’s instructions.

Making Purchases:

With an activated credit card, you can use it to make purchases at various merchants, both in-person and online. To complete a transaction, you provide your credit card information, including the card number, expiration date, and security code (CVV/CVC). Some transactions may also require your signature or a PIN (Personal Identification Number) for added security.

Billing Cycle and Statements:

Credit card usage is tracked based on billing cycles, which typically last for about 30 days. During this period, all your transactions and charges are recorded by the credit card issuer. At the end of each billing cycle, the issuer generates a statement that outlines the details of your transactions, including the merchant, date, and amount spent.

Minimum Payment and Interest Charges:

The credit card statement specifies a minimum payment amount that you are required to make by the due date. This payment typically represents a percentage of the outstanding balance, such as 1-3% of the total amount owed. If you only make the minimum payment, the remaining balance carries over to the next billing cycle and accrues interest charges. It’s important to note that interest is applied to the unpaid balance, and the interest rate is known as the Annual Percentage Rate (APR).

Credit Card Fees:

Credit cards may come with various fees, such as an annual fee, late payment fees, cash advance fees, and foreign transaction fees. These fees vary depending on the credit card issuer and the specific terms and conditions associated with your card. It’s crucial to review the fee structure before applying for a credit card.

Credit Score and Credit History:

Using a credit card responsibly can positively impact your credit history and credit score. Timely payments, keeping credit utilization low, and maintaining a positive payment history contribute to building a strong credit profile. Conversely, missing payments or carrying a high balance relative to your credit limit can have a negative impact on your credit score.

Credit Card Rewards and Benefits:

Many credit cards offer rewards programs, cashback incentives, or other benefits as an additional perk. These rewards can vary, such as earning points for every dollar spent, cashback on specific categories, or airline miles for travel-related expenses. It’s important to understand the terms and conditions of the rewards program and assess whether the benefits align with your spending habits and financial goals.

Responsible Credit Card Usage:

To make the most of your credit card while maintaining a healthy financial position, it’s crucial to use it responsibly. This includes paying your bills on time, keeping track of your spending, avoiding excessive debt, and reviewing your statements regularly for any errors o

Benefits of Using Credit Cards:

a) Convenience: Credit cards offer a convenient and secure way to make purchases both online and in-store, eliminating the need to carry cash or write checks. They provide immediate access to funds and simplify the payment process.

b) Fraud Protection: Credit cards often come with robust fraud protection measures, such as zero liability policies. In case of unauthorized transactions, cardholders are typically not held responsible for fraudulent charges.

c) Building Credit History: Responsible credit card usage can help individuals build a positive credit history. Timely payments and keeping credit utilization low can contribute to an improved credit score, which is essential for future financial endeavors like obtaining loans or favorable interest rates.

d) Purchase Protection: Many credit cards offer purchase protection benefits, such as extended warranties, price protection, and coverage against damage or theft. These perks can provide peace of mind when making significant purchases.

What’s the difference between credit & debit cards

Credit and debit cards are both widely used for making payments, but they work in different ways. Here are the key differences between credit and debit cards:

Source of Funds:

Credit Card: When you use a credit card, you are essentially borrowing money from the card issuer to make the purchase. The credit card company extends you a line of credit, up to a predetermined credit limit. You are required to repay the borrowed amount to the credit card issuer, either in full or in minimum monthly payments.

Debit Card: With a debit card, the funds used for the transaction are directly deducted from your checking account or linked bank account. You are spending your own money that you have deposited into the account.

Spending Limit:

Credit Card: Credit cards have a predetermined credit limit, which represents the maximum amount you can borrow and spend on the card. This limit is set by the credit card issuer based on factors like your credit history, income, and other financial information.

Debit Card: Debit cards typically have a spending limit equal to the available balance in your linked checking or bank account. You can only spend the funds that you have in your account.

Credit and Debt:

Credit Card: When you use a credit card, you are essentially creating a debt that needs to be repaid. If you do not pay the full balance by the due date, interest charges will be applied to the remaining balance, which can lead to accumulating debt.

Debit Card: Since debit cards deduct funds directly from your account, there is no credit or debt involved. You are using your own money, and there is no need to repay any borrowed amount or pay interest charges.

Impact on Credit History:

Credit Card: Responsible use of a credit card can help you build a positive credit history. Making timely payments, keeping credit utilization low, and maintaining a good payment history can contribute to a strong credit profile, which can be beneficial for future loan applications or obtaining favorable interest rates.

Debit Card: Using a debit card does not directly impact your credit history because there is no borrowing involved. Debit card transactions do not get reported to credit bureaus and, therefore, do not contribute to your credit score.

Overdraft Protection:

Credit Card: If you make a purchase exceeding your available credit limit on a credit card, it may result in declined transactions or over-limit fees. However, some credit cards offer overdraft protection, allowing you to exceed your credit limit by a certain amount, subject to additional fees or interest charges.

Debit Card: Without proper overdraft protection, using a debit card for a purchase exceeding your account balance may result in declined transactions or insufficient funds fees. Overdraft protection options vary depending on your bank, and they may allow you to link a savings account or a credit line to cover any overdrafts.

It’s important to note that both credit and debit cards offer convenience and security in making payments. The choice between the two depends on your financial goals, spending habits, and preference for using your own funds or accessing credit.


Having a credit card can be beneficial for building credit, but responsible usage is crucial to avoid excessive debt. Before applying for a credit card, it’s important to carefully review and understand the terms and conditions provided by the financial institution.
