Credit Card: What It Is, How It Works, and How to Get One

Credit cards are financial tools that allow consumers to borrow funds to make purchases or pay for services. Unlike debit cards, which draw money directly from your bank account, credit cards let you access a pre-approved credit limit that you must repay, usually with interest, if not paid off within a certain period. Understanding how credit cards work can help you use them wisely and avoid common pitfalls.

How Do Credit Cards Work?

When you use a credit card to make a purchase, the card issuer temporarily covers the cost on your behalf. You then repay the issuer either in full by the due date or over time through minimum payments. If you choose to pay over time, interest charges typically apply.

Key Features of Credit Cards

1. Credit Limit

Your credit limit is the maximum amount you can borrow using the card. This limit is determined by your income, credit score, and the policies of the card issuer.

2. Interest Rates (APR)

The annual percentage rate (APR) represents the cost of borrowing on the card if you carry a balance. Paying your bill in full each month helps you avoid these charges.

3. Minimum Payments

This is the smallest amount you must pay each month to keep your account in good standing. However, paying only the minimum can lead to significant interest charges over time.

4. Rewards and Benefits

Many credit cards offer rewards like cashback, travel points, or discounts. Additionally, some cards include perks such as travel insurance, purchase protection, and extended warranties.

Types of Credit Cards

There are various types of credit cards, each designed to suit different financial needs:

Rewards Credit Cards: Offer points, cashback, or travel miles for every dollar spent. For example, the Chase Sapphire Preferred® Card provides bonus points on travel and dining purchases.
Low-Interest Credit Cards: Feature lower APRs, ideal for those who may carry a balance. An example is the Citi® Diamond Preferred® Card, which offers an introductory 0% APR for a specific period.
Balance Transfer Cards: Allow you to transfer existing debt to a card with a lower interest rate. The Discover it® Balance Transfer card, for instance, offers an introductory 0% APR on balance transfers.
Secured Credit Cards: Require a cash deposit and are great for building or rebuilding credit. For example, the Capital One Platinum Secured Credit Card is designed for those with limited or poor credit.
Student Credit Cards: Tailored for college students with limited credit histories, often with low fees and rewards. The Discover it® Student Cash Back card offers cashback rewards and no annual fee.
Business Credit Cards: Provide features and rewards suited to business expenses and management. An example is the American Express® Business Gold Card, which offers rewards on business-related purchases.
Travel Credit Cards: Offer travel-related benefits such as miles, hotel discounts, and no foreign transaction fees. The Capital One Venture Rewards Credit Card, for example, provides miles that can be redeemed for travel expenses.

Building Credit History: Responsible use of a credit card helps build and improve your credit score.
Emergency Access to Funds: Credit cards can provide a financial safety net in urgent situations.
