Coming to the core question, what is credit card? A credit card is a financial tool issued by banks or financial institutions that allows cardholders to borrow up to a predetermined limit to make purchases, withdraw cash, or transfer balances. Now, compared to debit cards, which draw funds directly from the cardholder’s bank account, credit cards provide a line of credit that must be repaid with interest if not paid in full by the due date.

Benefits of Using a Credit Card

1. Convenience

 Credit cards offer unparalleled convenience, allowing users to purchase without needing cash. They can be used for in-person, online, and over-the-phone transactions, providing flexibility in payment methods. This convenience extends to various scenarios, such as emergencies where immediate access to funds is required or when travelling abroad, eliminating the need to carry large amounts of currency.

2. Rewards

Many credit cards offer rewards programs where cardholders earn points, cashback, or miles for every purchase. These rewards can be redeemed for various benefits, including travel, merchandise, statement credits, or gift cards, providing additional value for using the credit card. Some cards offer bonus rewards for specific categories such as dining, groceries, or travel, allowing cardholders to maximise rewards based on their spending habits.

3. Building Credit

 Responsible use of credit cards can help individuals build and improve their credit history and credit score. Making timely payments and maintaining a low credit utilisation ratio demonstrates creditworthiness to lenders, making it easier to qualify for loans and other financial products in the future. Furthermore, having a positive credit history opens up opportunities for favourable interest rates and terms on future credit applications.

4. Protection

Credit cards offer protection against unauthorised transactions and fraudulent activities. Leading banks often provide features like zero-liability fraud protection and total protection, which cover cardholders in case of loss, theft, or unauthorised credit card use, offering peace of mind and financial security. Some credit cards offer purchase protection, extending warranties and insurance coverage for items purchased using the card, further enhancing consumer protection.

5. Travel Benefits

 Certain credit cards offer exclusive travel benefits such as travel insurance, airport lounge access, concierge services, and discounts on travel-related expenses. These perks can enhance the travel experience, save money on travel costs, and provide added convenience and security. Travel rewards credit cards often offer accelerated rewards earning rates for travel-related spending, allowing cardholders to earn more rewards for their travel expenses.

How Do Credit Cards Work?

1. Creditworthiness Evaluation

    When applying for a credit card, the bank or financial institution assesses the applicant’s creditworthiness based on factors like credit score, income, and employment history. This evaluation determines the credit limit assigned to the cardholder, reflecting their ability to manage credit responsibly.

    2. Credit Limit

       Upon approval, the cardholder is assigned a credit limit, representing the maximum amount they can borrow using the credit card. The credit limit is determined based on the applicant’s creditworthiness and the specific credit card applied for. Higher credit limits are granted to individuals with higher credit scores and stable income levels.

      3. Making Purchases

        Cardholders can use their credit cards to purchase at merchants accepting credit card payments. Each transaction adds to the cardholder’s outstanding balance, which must be repaid by the due date to avoid interest charges. Credit availability allows cardholders to make purchases even when they do not have sufficient funds in their bank accounts, providing a convenient payment option for everyday expenses and larger purchases.

        4. Billing Cycle and Statements

           Credit card transactions are grouped into billing cycles, typically lasting around 30 days. At the end of each cycle, the cardholder receives a statement detailing their transactions, outstanding balance, minimum payment due, and any fees or interest charges incurred. Reviewing the statement allows cardholders to track their spending, identify unauthorised transactions, and manage their finances effectively.

          5. Minimum Payment and Interest

             Cardholders must make at least the minimum payment specified in the statement by the due date to avoid late payment fees and penalties. If the outstanding balance is not paid in full, interest is charged on the balance, usually at a rate based on the card’s terms and the cardholder’s creditworthiness. Paying the balance in full monthly avoids interest charges, allowing cardholders to use credit without incurring additional costs.


            Credit cards offer many benefits, including convenience, rewards, credit-building opportunities, protection against fraud, and travel perks. However, it’s essential to understand how credit cards work and use them responsibly to avoid debt and negative impacts on credit scores. By leveraging the benefits of credit cards while managing finances prudently, individuals can maximise the value of their credit cards and achieve their financial goals effectively.
