Credit Card is more safe then Cash . How it is? If you want to buy a Colour T.V., you have a cash in your purse and some thing happen, your purse is not in your pocket. What you will do? Will you get back the cash? No not at all but , if, in your purse credit card is there, then you can Block the Credit card. After block the card, no one can use your Credit Card .
Second, if you are going to buy Gold, will you get credit for a month from jwellers? No, but if you have Credit Card you will get credit facility for 50 days.
However, if you are travelling, you have some budget for expense and suddenly your travel plan will be change, will you manage your expence I mean budget? No, you have to go through previous travel plan.
These are in my mind but lot many advantages are there
