When you apply for a credit card,you apply to borrow money from the card issuer,usually a bank or building society.The issuer then looks at your credit history to consider your application-and if you have a low credit score you could be refused credit,or perhaps given a less attractive deal on interest rate. If you have a good credit rating,then you will be accepted and the bank will set a credit limit,which is the maximum amount you can spend on the card.The card company will send you a statement every month,detailing any transactions on your card,plus the amount owing.It also provides details on the minimum payment you need to make(this depends on how much you have your balance)and the payment due date.
