Who doesn't like earning while spending? This may not be possible. But with credit cards it is somewhat possible. Credit cards give cashback in the form of rewards. This cashback is received as a part of the expenses incurred by cardholders using the card. This cashback is either credited to the cardholder's account or adjusted at the time of next bill payment, reducing the total cost at the time of transaction. When using a credit card for purchases, a portion of the transaction amount is returned to the cardholder in the form of cashback. This part depends on the terms and conditions of the card and the nature of the transaction.
