What is a credit card?

A credit card is a plastic card that allows you to borrow money from a bank or other financial institution to make purchases. When you use your credit card, you are essentially taking out a short-term loan. You will have to pay back the loan, plus interest, within a certain period of time.

How do credit cards work?

When you make a purchase with your credit card, the merchant swipes your card through a machine. This machine sends information about the purchase to the credit card company. The credit card company then approves or declines the purchase. If the purchase is approved, the credit card company sends the money to the merchant.

You will receive a bill from the credit card company at the end of each month. The bill will list all of the purchases you made during the month. You will have to pay the balance on the bill, plus interest, by the due date.

There are many benefits to using a credit card. Credit cards can help you build your credit history, earn rewards, and protect your purchases.

  • Earning rewards: Many credit cards offer rewards programs that allow you to earn points or miles for every dollar you spend. These rewards can be redeemed for travel, merchandise, or cash back.
  • Protecting your purchases: Credit cards offer purchase protection, which means that you are covered if your purchase is lost, stolen, or damaged.
