Are credit cards a necessity? Perhaps some ten years ago, the answer to this question may be a "No", but these days, not having a credit card could be a handicap. Would anyone think of carrying tens of thousands of dollars in cash around town shopping? Here in Malaysia personal cheques are normally not accepted for walk-in shopping. Generally, shopkeepers do not accept them. They would prefer a credit card instead. No wonder sometimes they are called 'plastic money'.
It is wise to learn about credit cards to tap their full potential as different cards do have different functions. For example, if one already has a few credit cards and would like to consolidate the balances to better manage the accounts, a 0% balance transfer credit card would be suitable. Having different cards for different purposes could be an ideal way to manage spending. The card used for shopping would be well to be charged to a 0% on all purchases or one where credit card loyalty points can be collected. Before you go out to sign up for a card, why not compare credit cards available to make a well-informed choice.
