28: Average credit limit on open bankcards is too low
Bankcard accounts include credit cards and charge cards from a bank and are frequently revolving accounts. They allow you to carry a balance and your monthly payment will vary, based on the amount of your balance. The amount of credit you have available to use on your open bankcard accounts is low. Having higher limits gives you access to credit without seeking new loans or becoming overextended, which are triggers for higher risk.
Use credit responsibly and always make payments on time with your existing accounts. After a period of successfully managing your accounts, you can seek increases to your credit limit.
