ARA: Credit Card Number Visible in Activity Log

I use my long distance credit card number when connecting with Apple Remote Access (ARA) by entering the number in the Long Distance Access field of the DialAssist control panel. I've noticed that the Activity Log shows my credit card number instead of black dots, and I'm concerned other people using my PowerBook can get my credit card number from the Log. Is there a way to hide my credit card number?
To keep your credit card number from appearing in the Activity Log, enter the credit card number in the Suffix field of the DialAssist control panel. If you enter your credit card information in the Long Distance Access field of the DialAssist control panel, the number will be visible in the Log.
