2. What Is a Credit Card?

• A credit card is a plastic (or metal) card issued by a bank or financial company.
• It lets you borrow money up to a set credit limit (say ₹50,000).
• When you use it to pay, the bank pays the merchant; you then owe the bank that amount.
• You must repay the bank later, either in full or as a minimum payment with interest on the rest.

3. Getting and Activating Your First Card

3.1 Eligibility

To get a card, you usually need:

• Age: At least 18 years old.
• Income: A minimum annual income (₹2–3 lakh for entry-level cards; higher for premium cards).
• Credit Score: A good credit history helps but new applicants can start with a secured card.
• KYC Documents: PAN card, Aadhaar, proof of income (salary slips or bank statements).

3.2 Types of Cards

• Secured Card: You deposit money (e.g., ₹10,000) as collateral; your limit equals your deposit.
• Unsecured Card: No deposit; bank decides your limit based on your income and credit.
• Lifetime-Free Card: No annual fee ever.
• Fee-Based Card: Charges an annual fee but offers better perks or rewards.
• Reward Card: Earns points or miles on every spend.
• Cashback Card: Gives you a percentage back as cash.
• Co-Branded Card: Partners with an airline, hotel, or retailer for extra benefits.

3.3 Activation

1. Receive Your Card: The bank mails it to you.
2. Sign the Back: For security, sign the signature strip.
3. Activate: Call the number on a sticker or use your bank’s app/website.
4. Set PIN: Create a 4-digit ATM PIN for cash withdrawals.

4. Making Purchases and Payments

4.1 How Purchases Work

When you swipe, dip, or tap your card:

1. The merchant’s terminal sends a request to your bank.
2. The bank checks your available limit.
3. If you have enough limit, the bank authorizes the transaction.
4. You get a receipt; the merchant gets paid later in a batch.
5. Your bank posts the charge to your card account.

4.2 Billing Cycle and Statement

• Statement Cycle: Usually 30 days. All transactions in that period appear on your monthly statement.
• Statement Date: The day your statement is generated (e.g., every 5th of the month).
• Due Date: Typically 20–25 days after the statement date. You must pay by this date to avoid interest.

4.3 Minimum Payment

• You must pay at least the minimum amount (2%–5% of the statement balance or ₹300, whichever is higher) by the due date.
• Paying only the minimum triggers interest on the unpaid balance.

5. Interest Rates and Fees

5.1 Interest (APR)

• APR (Annual Percentage Rate): The yearly interest rate on unpaid balances, often 24%–36%.
• Daily Interest: Many banks calculate interest daily on your closing balance.
• Compound Interest: Interest accrues on interest if you carry a balance.

5.2 Grace Period

• If you pay the full statement balance by the due date, you enjoy an interest-free period on new purchases—usually 20–25 days.
• Missing full payment means you lose the grace period and start paying interest on every new purchase immediately.

5.3 Common Fees

6. Grace Period and Avoiding Interest

To avoid interest:

1. Pay Full Balance: Always pay the entire statement amount by the due date.
2. Use Auto-Pay: Set up auto-debit for the full amount.
3. Track Your Spending: Monitor your balance via SMS alerts or your banking app.

Missing even one payment means your interest-free period ends and you start paying interest on your entire balance.

7. Rewards, Points, and Cashback

7.1 Reward Points

• Earn points on each ₹100 spent (e.g., 1 point/₹100).
• Redeem points for gifts, travel bookings, or statement credit.
• Points often expire in 6–12 months—redeem before expiry.

7.2 Cashback

• Earn a fixed percentage back on spends (e.g., 1% on all purchases, up to ₹2,000/month).
• Cashback is credited as statement credit or to your bank account.

7.3 Special Categories

• Cards may offer higher rates (3%–5%) in categories like groceries, dining, fuel, and online shopping.
• High rates often have monthly caps (₹3,000–₹10,000). After cap, you earn the base rate (0.2%–1%).

8. Reading Your Statement

Your monthly statement shows:

• Statement Period: Dates covered.
• Opening & Closing Balance: What you owed at start and end.
• New Transactions: List of purchases, cash advances, fees, credits.
• Minimum Payment: Amount due to keep your account in good standing.
• Due Date: Final date to pay without penalty.

Review each statement carefully for errors or unauthorized charges.

9. Credit Limit and Utilization

9.1 Credit Limit

• The maximum you can borrow on your card.
• Banks set it based on your income, credit score, and relationship with them.

9.2 Credit Utilization

• The ratio of your current balance to your limit (Balance ÷ Limit).
• Aim to keep utilization under 30%—this helps your credit score. For a ₹50,000 limit, keep balances under ₹15,000.

10. Building Credit History

Your credit score (300–900) reflects your trustworthiness to lenders. Good habits help you score high:

1. On-Time Payments: Pay at least the minimum by the due date every month.
2. Low Utilization: Use under 30% of your limit; spread spends across cards if you have more than one.
3. Long Account History: Keep your card active for many years; older age raises your score.
4. Limited Applications: Each new card application might dip your score slightly.
5. Mix of Credit: Over time, having both a credit card and a small loan can help.

A strong credit score makes future loans (home, auto) cheaper and easier to get.

11. Smart Tips for Using Your Credit Card

1. Track Spending Daily via app or SMS.
2. Set Alerts for approaching your limit or bill due date.
3. Use Auto-Pay to clear full balance each month.
4. Avoid Cash Advances—they carry high fees and immediate interest.
5. Redeem Rewards regularly before they expire.
6. Review Statements for fraud; report unknown charges immediately.
7. Negotiate Fees—ask your bank for a lower interest rate or annual fee waiver if you have good history.
8. Use Balance Transfers Carefully only if introductory rates truly save you money.

12. Common Mistakes and How to Avoid Them

13. What to Do If You Can’t Pay

If you face hardship (job loss, medical emergency):

1. Contact Your Bank ASAP: Explain your situation; they may offer a hardship program.
2. Ask for Lower APR: Negotiation can sometimes lower your rate.
3. Make Minimum Payments: To avoid late fees and keep account current.
4. Seek Credit Counselling: Nonprofit agencies can help you set up a budget and negotiate with lenders.

Ignoring the problem only makes it worse—face it early and seek solutions.

14. Summary

Credit cards are powerful financial tools when you know how they work:

• You borrow up to a credit limit, then pay back.
• Full payments by the due date avoid interest; minimum payments lead to expensive interest.
• Rewards and cashback can save you money—but watch caps and fees.
• Keep utilization under 30% and payments on time to build a strong credit score.
• Use auto-pay and alerts to avoid mistakes and fees.
• In hardship, communicate with your bank and consider counselling.

By following these simple principles, you can use credit cards safely, avoid debt traps, and enjoy the convenience and rewards they offer. Happy spending—and happy paying!
