Your credit card provider will share information with credit reference agencies about the way you use your card to update your credit score. This information will help other creditors decide how risky it is to lend money to you.
Credit files state the balance owed, your payment history and if the account has defaulted. Credit card providers give extra information to the credit file companies, including:
Your credit limit
How much you’ve spent each month
How much money you’ve withdrawn from a cash machine each month
