What Is a Credit Card?
A credit card is a financial payment tool issued by banks or financial institutions that allows users to borrow money up to a pre-approved credit limit for purchases, bill payments, or cash withdrawals.
Unlike debit cards, credit cards let you spend first and repay later.
Credit cards are commonly used for:
- Online shopping
- Travel bookings
- Utility bill payments
- Business expenses
- Emergency purchases
- Subscription services
- Cashback and reward programs
Responsible credit card usage can also help improve your credit score over time.

APR (Annual Percentage Rate) determines how much interest you pay yearly.

|---|---|
| Excellent | 12% – 18% |
