Let’s break down everything you need to know before swiping.
What is a Credit Card?
A credit card is a financial tool issued by a bank or credit institution that allows you to borrow money to pay for purchases, with the promise to pay it back later — usually within 30 days or with interest if delayed.
Key Features:
- Instant buying power
- Revolving credit (you can reuse your limit)
- Interest-free period (15–55 days)
- Cashback, points, and offers
“A credit card gives you financial flexibility — if you know how to use it.”
How Credit Cards Work
Here’s a simple breakdown:
- You swipe the card to buy something.
- The card issuer pays the merchant.
- You get a monthly bill.
- You pay the full amount (no interest) or minimum (interest charged).
Example:
You buy a laptop worth $1,000. If your card offers 45 days interest-free, and you pay the full $1,000 before that — no interest is charged. Delay it, and you could pay up to 25% APR.
