If you are using a payment processor to process your credit card transactions our system will try to store the actual credit card information along with authorization and verification numbers for transactions which can be used to look up the actual transaction on the processors website.
To view sensitive information such as credit card information you must be logged in securely. This is done to ensure the security of your customers information. Some gateways do not allow the shopping cart to store the credit card information. In this case you will see an NA listed as the credit card number.
If you see only the last 4 digits of the credit card number you are not logged in securely. Click on the link below the credit card number that says, click here to switch to secure mode.
