Why should you use a credit card?
Traditional mode of commercial or domestic transaction whether by cash or check is now outdate and is being slowly but steadily replaced by electronic transaction modes. In the past you used to go over to the brick and concreter store or the local market to get your requirements, however sophisticated it would be since the concept of state level or international level market was a distant feature for you. Today, the scenario is completely different and neither it is convenient nor safe to carry huge cash in your pockets to carry out the transactions. A small plastic card can do the trick and that is why a credit card is so popular and widely used to day.
Do not confuse credit card with your ATM card. The later will be used to take out money from the ATM cash counters spread over the town or when you are on a tour but again once you are with the cash, the vulnerability creeps in. Pickpockets and burglars are present all over and they are more active in busy market places where thousands of people simultaneously go shopping. It is much more convenient now to use a credit card where the activation number is secret in your mind and no one can hike it from there. Of course there is always a credit limit attached to your Visa card or Master card but it is most unlikely that you will need to cross the limit that is fixed with your own consent.
