The RCS system matches the attendee's interests with the exhibitor’s products, providing attendees with potentially valuable contact information prior to the event. After attendees fill out the simple on-line registration page they are provided with a list of companies that match the demographic choices they made while registering. Should the attendee have an interest in one or more of the exhibiting companies that match with their interests, the system will provide their information to the exhibitor, or, they can choose to simply contact the companies themselves, without divulging their personal information. The attendee has full control over which companies have access to their information, if any. EES was developed to help show organizers increase the value of their event.
