iBill Gateway
This script allows you to easily manage your pay site with automation via the iBill Billing Company. After the surfer uses their credit card or calls a 900 number through iBill's services, the iBill Gateway takes over the sign-up process, giving the new user his choice of username and password. Your customer accounts are INSTANTLY activated and there's no need to have insecure methods of membership, including preset username/passwords or daily updated single username/password combinations.
