In the fast-paced world of personal finance, credit cards have become indispensable tools, offering users convenience, flexibility, and a range of benefits. Understanding how credit cards work is essential for financial decisions and it will help you choose the right credit card and guide you when to use it.

A credit card is a financial tool that allows individuals to borrow money up to a predetermined limit. Unlike debit cards, credit cards provide a line of credit for making purchases or accessing limited cash, with the obligation to repay the borrowed amount later.

They offer various benefits but may incur interest if the full balance is unpaid within a specified grace period. Responsible use can positively impact credit history and scores.

The key aspects of understanding how credit cards operate will help make informed financial decisions:

• Credit Limit and Issuance: Credit cards come with a predetermined credit limit, indicating the maximum amount a cardholder can borrow. Issuance involves an evaluation of creditworthiness, income, and financial history, determining the initial credit limit.
• Making Purchases: Cardholders utilise credit cards Credit cards can be utilised to make purchases at various merchants, whether online or offline. With each transaction, the cardholder essentially borrows money from the credit card issuer, forming the basis of the credit card's functionality.
• Billing Cycle and Statements: Credit cards operate on billing cycles, typically lasting one month. Throughout this period, all transactions made with the card are compiled into a statement, providing a comprehensive overview of the cardholder's monthly financial activity.
• Grace Period: It is a valuable time frame typically spanning 21 to 25 days, during which cardholders have the opportunity to settle their outstanding balances without incurring any interest. This period provides a window for interest-free repayment before the due date.
• Minimum Payment and Interest Rates: If the full balance is not repaid within the grace period, a minimum payment is required. Interest is then charged on the remaining balance, often at variable rates based on the terms and conditions of the credit card.
• Impact on Credit Score: Credit card usage, timely payments, and managing balances contribute to the cardholder's credit history and credit score. Responsible credit card management positively influences creditworthiness. A higher credit score opens doors to improved overall financial opportunities.

Selecting the right credit card involves consideration of several strategic factors, such as:

• Assessing Spending Habits: Consider your predominant spending patterns, whether on travel, groceries, or general expenses. Choose a credit card that offers rewards aligned with your lifestyle to optimise benefits.
• Considering Interest Rates: Understand the interest rates associated with the credit card, especially if you anticipate carrying a balance. Low-interest cards may be preferable for those who occasionally carry balances.
• Evaluating Annual Fees: Some credit cards come with annual fees. Evaluate whether the benefits, rewards, or cashback offered outweigh the cost of the annual fee. Opt for a card where the benefits justify the associated costs.
• Reviewing Rewards Programs: Diverse credit cards offer varied rewards programs, including cashback, travel miles, or points for specific purchases. Choose a card with rewards that align with your preferences and provide tangible value.
• Comparing Introductory Offers: Many credit cards come with introductory offers, such as 0% APR for a specified period. Consider these offers, especially if you plan to make significant purchases, and assess how they align with your goals.

• Building Credit: Using a credit card responsibly is a key method for establishing and maintaining a positive credit history. Regular, small purchases coupled with timely payments contribute positively to your credit score.
