Locate the bank that issued you the MasterCard. Check the front of your MasterCard credit card for the bank that issued the credit card.
Navigate to the bank's website. Once you arrive at the bank's website search for the link that allows you to access the credit card section of the website.
Create a personal account for online banking. You must provide your name, the credit card number, expiration date, billing address, the signature panel code or CVV number, and your Social Security number. You must also create a user name and password to access your account in the future.
Click on the "Bill Pay" or "Pay My Credit Card" link in your account. Once you have created your personal account, navigate to the area that allows you to pay your credit card bill. You will have to enter your bank account information, such as the name of the bank, the bank account number, and the bank's routing number. This information can be found on a check or a deposit slip. You can also contact your bank and request this information.
Enter you payment amount and posting date. You can choose to pay the minimum amount due or another amount if you wish to pay more. You may also select a date upon which you would like the payment to post. Click the button that allows you to continue the payment process.
Verify the payment information. Prior to completing the payment process, you will be given the opportunity to verify the payment information. Check to make sure that the bank account number, the posting date, and the amount to be paid are correct, then submit your payment.
Write down your confirmation number that you will receive after your payment has been successfully submitted. Keep it for future reference until the payment has cleared your bank and posted to your credit card account.
