RegisterConvention.com is a state-of-art registration system for event/conference organisers. We have more than 15 years of experience managing registration for large scale events. Our software allows participants to register online for the event, select their flight, hotel and meal preferences. In recent years, we have also developed mobile applications for onsite registration. With the mobile application, event participants can view the event information and scan their barcode for marking attendance. This greatly improves the productivity for event organisers and reduce the queuing time for event participants.
