How does the online shopping cart handle the credit card authorization process?
The shopping cart communicates with a credit cart authorization service company that validates the information you entered into the shopping cart. All of the credit card authorization communication to and from the site is encrypted for security purposes. If any of the information you enter does not match the validation information, the charge authorization will be denied. Common errors include using a bill-to address that is different from the address on the credit card statement, entering the incorrect type of credit card, and entering an incorrect expiration date or security number.
