Credit card allows cardholders to borrow funds up to a predefined credit limit to pay for goods and services. It can be used to make payments at POS terminals and pay for online transactions. The credit limit is decided by the issuer on the basis of the applicant’s income, credit score, existing debt and several other internal policies of the issuer.

On your credit card, you can see details like credit card number, expiry date, name of the cardholder and CVV. All these are important when registering your card for online payment.

For every transaction, credit cards reward the users in the form of reward points, cashback, air miles, discount, etc. As long as you clear your total dues on time and do not withdraw cash, no interest charges are applicable on credit card balances.
