What is a Credit card?

Credit card: What is it?

A credit card is part of a system of payments named after the small plastic card issued to users of the system. It is a card entitling its holder to buy goods and services based on the holders promise to pay for these goods and services. The issuer of the card grants a line of credit to the consumer (or the user) from which the user can borrow money for payment to a merchant or as a cash advance to the user.

How does it work?

After you or the cashier swipes your credit card through a reader, the EDC software at the point-of-sale (POS) terminal of the establishment that you are using your credit card at dials a stored telephone number (using a modem) to call an acquirer. An acquirer is an organization that collects credit-authentication requests from merchants and provides the merchants with a payment guarantee. Put simply, the card is swiped at the establishment>the bank or financial institution is contacted>authenticity is established>payment is approved>receipt is received.

  • Purchasing power increases because of the higher credit limit being offered to customers
  • Almost all major establishments accept credit cards
  • You can buy things online
  • Credit cards also serve those who frequently travel internationally


  • Uncontrolled spending can result in a bad financial situation
  • Credit cards are prone to security issues when spending online
  • Credit cards impose high interest rates and other applicable fees. So if you do not make the payments as soon as possible, you might end up paying more than the price of the item or service you purchased.

    Dos and Don't s

  • Dos


    Make wise decisions about purchasing items you need versus those you simply want. It is important to distinguish between the two.

    Use your credit card to make everyday purchases like food, clothing, and petrol. Using your credit card as a substitute for cash will land you in unnecessary debt.

    Pay on time, within the due date. Consecutive missed payments will make you defaulter and result in a poor credit score.

    Get into the habit of making minimum-only payments. Making only the minimum payment each month increases the amount of time it will take to pay off your debt.

    Stay within 30% of your credit limit.

    Use your credit card to buy things you can't afford.

    Read your credit card statement carefully.

    Withdraw cash from an ATM using your credit card. Not only will you be charged a withdrawal fee, but the interest will levied from the moment the cash is withdrawn
