Credit cards offer a convenient way to make purchases while building your credit history. When used wisely, they provide numerous benefits like reward points, cashback, discounts, and even travel perks. Most credit cards come with a grace period where no interest is charged if you pay the full bill on time. However, missing payments or overspending can lead to high-interest charges and a damaged credit score. Always compare cards based on annual fees, interest rates, and rewards to choose what fits your lifestyle. For maximum benefit, pay your dues in full, avoid cash withdrawals, and monitor your spending. A credit card is a powerful financial tool—only if handled with discipline.
