What is a Credit Card?

A credit card is a financial instrument that enables cardholders to borrow funds from a financial institution up to a specified limit, known as the credit limit. Unlike a debit card, which directly deducts money from a checking or savings account, a credit card allows the cardholder to make purchases on credit, to be repaid at a later date.

How Credit Cards Operate

When a cardholder uses a credit card for a purchase, the card issuer pays the merchant on behalf of the cardholder. The cardholder is then required to reimburse the amount borrowed, either in full or through installment payments, as stipulated in the card agreement.

Interest is levied on the outstanding balance if not paid in full by the due date. The interest rate, often referred to as the Annual Percentage Rate (APR), varies depending on the card issuer and the cardholder’s creditworthiness.

Types of Credit Cards

Various types of credit cards are available, each tailored to cater to different financial needs:

a. Standard Credit Cards: These are fundamental cards with a set credit limit and standard features.

b. Rewards Credit Cards: These cards offer various rewards such as cashback, travel points, or discounts on specific purchases.

c. Secured Credit Cards: Designed for individuals with limited or poor credit histories, these cards necessitate a security deposit, which then becomes the credit limit.

d. Premium or Luxury Credit Cards: These cards come with high annual fees but offer premium benefits like concierge services, travel perks, and exclusive access to events.

e. Business Credit Cards: Tailored for business owners, these cards come with features and rewards designed to meet business-related expenses.
