Understanding Credit Cards: What They Are and How They Work

Credit cards have become an essential part of modern financial transactions, offering convenience, rewards, and financial flexibility. However, many people still have questions about how credit cards function and how they can be used effectively without falling into debt. This blog provides a comprehensive guide to credit cards, including their advantages, disadvantages, usage in different countries, and key considerations for users.

How Credit Cards Work

A credit card is a financial tool that allows users to borrow money from a bank or financial institution up to a pre-approved limit. The user can make purchases, pay bills, or withdraw cash (cash advances) using the credit card. However, the borrowed amount must be repaid within a specific period. If the full balance is not paid by the due date, the remaining amount accrues interest.

The Functioning of a Credit Card

  • Issuance and Credit Limit:

    When you apply for a credit card, the issuing bank assesses your creditworthiness based on factors such as income, credit score, and repayment history. Based on this, they assign a credit limit.

  • Making Purchases:

    Credit cards can be used for transactions at various merchants, online platforms, and even for utility payments.

  • Billing Cycle and Repayment:

    Each month, the bank generates a statement listing all transactions made using the credit card. If you pay the full amount before the due date, you avoid interest charges.

  • Interest on Outstanding Balances:

    If you carry forward any unpaid balance, interest is charged based on the applicable interest rate, which is typically high.

  • Fees and Charges:

    Some credit cards have annual fees, late payment fees, and cash withdrawal fees. Understanding these charges is crucial to managing credit effectively.

How Credit Card Companies Make Money

Credit card issuers generate revenue through multiple streams, including:

  1. Interest on Unpaid Balances:

    If users do not pay the full amount, high-interest charges apply.

  2. Annual Fees:

    Many credit cards come with an annual fee, especially premium ones that offer added benefits.

  3. Merchant Transaction Fees:

    When a customer makes a purchase using a credit card, the merchant pays a small fee to the credit card issuer.

  4. Late Payment and Other Charges:

    Banks impose fees on late payments, cash advances, and over-limit transactions.

Advantages and Disadvantages of Credit Cards

While credit cards offer numerous benefits, they also come with certain risks. Let’s explore both aspects.

  1. Advantages of Credit Cards

    • Cashback and Rewards: The best credit card offers cashback, rewards, or loyalty points on transactions, which can be redeemed for travel, shopping, and other perks.
    • Convenience and Security: Credit cards are widely accepted globally, making them ideal for online shopping and travel bookings. Additionally, they provide fraud protection against unauthorized transactions.
    • Building Credit History: Timely repayment of credit card bills helps build a good credit score, which is essential for obtaining loans.
    • Emergency Financial Backup: Credit cards can serve as a financial cushion during emergencies when immediate funds are required.
    • Lounge Access and Travel Benefits: Premium credit cards provide airport lounge access, free travel insurance, and discounts on hotel bookings.

  2. Disadvantages of Credit Cards

    1. High-Interest Rates: If you do not pay your bill in full, the interest charges on the outstanding balance can be substantial.
    2. Debt Trap: Misusing a credit card can lead to debt accumulation, making it challenging to repay.
    3. Annual Fees and Hidden Charges: Some credit cards come with high annual fees, which may not be justified by the benefits.
    4. Overspending Risk: The easy availability of credit often tempts users to spend beyond their means.

Credit Cards in India and Internationally

  1. How Credit Cards Work in India?

    Credit cards in India function similarly to those in other countries. Users apply for a credit card, get approved based on their credit profile, and use the card for transactions. Many banks offer EMI (Equated Monthly Installment) options, allowing users to convert big purchases into manageable monthly payments. Popular credit card issuers in India include HDFC Bank, SBI Card, ICICI Bank, and Axis Bank.

  2. Can Credit Cards Be Used Internationally?

    Yes, credit cards are widely accepted worldwide. Visa, MasterCard, and American Express credit cards are commonly used for international transactions. However, users should check for foreign transaction fees and ensure that their card is enabled for international use.

  3. Credit Cards in Bhutan

    Credit cards are accepted in major establishments such as hotels, shopping malls, and restaurants in Bhutan. However, rural areas may not have widespread credit card acceptance, so carrying cash is advisable.

Common Concerns About Credit Cards

  1. Are Credit Cards Good or Bad?

    Credit cards are neither good nor bad—it all depends on how they are used. When managed responsibly, they provide financial flexibility, rewards, and credit-building opportunities. However, misuse can lead to high debt and financial stress.

  2. Why Credit Cards Are Bad?

    Some people view credit cards negatively due to:
    High-interest rates on unpaid balances
    The risk of falling into debt
    The temptation to overspend
    Hidden fees and charges

  3. Are Credit Cards Necessary?

    While credit cards are not strictly necessary, they offer advantages such as convenience, rewards, and credit score improvement. Alternatives include debit cards and UPI-based payments.

  4. Can Credit Cards Garnish Your Wages?

    If a credit card user fails to repay their debt, the issuer may take legal action. In extreme cases, a court may order wage garnishment to recover outstanding dues.

  5. Special Features and Offers

    Many credit cards come with exclusive benefits tailored to different user needs.

  6. Credit Cards with Lounge Access

    Premium credit cards such as HDFC Diners Club, SBI Elite, and ICICI Sapphiro provide complimentary airport lounge access through Priority Pass or other lounge programs.

  7. Best Credit Card for Cashback and Rewards

    If you’re looking for the best credit card for cashback, consider cards like HDFC Regalia, Amazon Pay ICICI, or Flipkart Axis Bank Credit Card, which provide attractive cashback and reward points.

  8. Metal Credit Cards

    High-end credit cards, such as the American Express Centurion and HDFC Infinia, are made from metal and offer elite privileges like personal concierge services, exclusive travel benefits, and luxury hotel partnerships.

Key Considerations for Credit Card Users

  • Why Credit Cards Offer Cash Back

    Credit card companies provide cashback to encourage spending and customer engagement. The cashback amount is typically a percentage of the transaction value.

  • Why Credit Cards Are Better Than Debit Cards

    Credit cards offer fraud protection, rewards, and the ability to build a credit score, unlike debit cards, which deduct money directly from your bank account.

  • Are Credit Cards Free?

    Some credit cards come with no annual fee, making them effectively free to use. However, premium cards with added benefits often have annual charges.

  • Can Credit Cards Be Used for UPI Payments?

    Some UPI platforms allow credit card linkage for payments, but not all services support this feature. Users should check with their bank for compatibility.

  • Why Credit Cards Are Bad for College Students?

    College students may struggle with managing expenses, leading to overspending and debt. Without a steady income, repaying credit card bills can become a challenge. However, with proper financial discipline, students can benefit from credit cards.

Conclusion

A credit card is a powerful financial tool that offers rewards, convenience, and credit-building opportunities. However, responsible usage is crucial to avoid high-interest debt and financial troubles. When choosing the best credit card, consider factors such as annual fees, rewards, cashback, and benefits that align with your spending habits. By using credit wisely, you can make the most of your card while maintaining financial stability.
