What are the advantages of using a credit card?

It is much safer carrying credit cards than carrying cash. It is a safer mode of payment, especially for large amounts, as one does not have to take the risk of theft that comes with holding large cash amounts. In case of theft too it is easier to minimize and recover from the loss. To give an example, Anita uses a credit card to pay for majority of her expenses. To her misfortune, her purse was stolen.

It contained Rs. 1,000/- in cash and a credit card with a credit limit of Rs. 25,000/-. She immediately lodged a police compliant and also called her credit card company to report the theft. Her credit card company immediately froze the card and hence nobody could use it to make unauthorized purchases. It also cancelled her existing card and sent her a new one within a week and she could start using it immediately.

Very helpful in case of an unexpected expense or an emergency

Credit card statements provide a detailed list of all your expenses. It is just easier to keep a record and track expenses incurred using credit cards. Keeping track of cash expenses becomes difficult as one spends more and more in cash. It is not practical to write down each expense.

I use it to make online payments to my cellphone companies. This is because the cellphone company does not have a facility to enable me to make a payment thru net banking system. 

Online shopping of international products.... there ur net banking n all doesnt help...
