Customers can make a credit card payment online by creating a Wal-Mart credit card account. Payments must be made through a suitable bank account, according to Wal-Mart.
To register for a Wal-Mart credit card account, go to the Account Registration page and fill out the information there, as stated by Wal-Mart. Once the account is registered, sign in to the account and follow the steps to make a payment. If it is the first online payment on that account, link the credit card account to a bank account by providing the account holder's name, the account number and the banking institution's routing number. Customers can also make online payments through CheckFree.
