To check a credit card balance online, the account holder needs to register and log in to his account on the bank’s online banking site, states Bankrate. The URL for the bank is typically located on the back of the card near the customer service phone numbers.
Once the account is registered, information such as account balance, limits and payment due dates for the credit card are available to view. Users can also perform transactions online, including make payments, update addresses, and create alerts based on user-defined criteria such as transaction amounts. Credit card websites use encryption methods to ensure the information being transmitted is secure, notes Bankrate.
