A credit card is a type of financial tool where the cardholder can make purchases with a pre-loaded amount and pay for them at a later time. You have up to 15 to 50 days from the date of payment to completely pay off the balance, interest-free, with the card issuer. Having a credit card makes spending easy, especially if you don't have much money. You’ll also receive discounts and earn incentives like cashback or points. The cardholder can pay the minimum amount due, which can be anything from 5% to 10% of the entire amount payable, to avoid any penalty.
