Credit Card Information

Displays a popup containing the client's credit card information (if using a merchant payment gateway) or the Token ID (if using a tokenisation payment gateway).

Adding a New Card

You can replace the existing card stored for a client or add one (if none is already stored) at the bottom of this page. Simply enter the card details (card issue and start date are optional) and click Save Changes.

Viewing Full Card Number

In order to view the full card number, on this screen you will see a text area asking for the CC Encryption Hash. This is the random hash key unique to your WHMCS installation which you can find in the configuration.php file. Enter the hash into the text area and click submit, the page will reload showing the full number.

Removing Card Details

If you would like to remove card details from a client, simply click the Clear Details button located at the bottom of the screen.
