So people should keep in mind the risk of using credit card and try to spend money wisely.First, before applying a credit card, people should make sure whether they can afford to pay back money spent on the card. Second, it is very important to work out what kind of card meets their needs. Third, people should try to pay their balance in full every month, or they will be charged interest and have negative effects on their credit scores.
