Subsplash Event Check-In
A streamlined mobile-first check-in solution that enables fast, contactless event entry with real-time attendance tracking and seamless integration with event management systems.

Problem
Event organizers needed a faster, more reliable check-in solution to reduce long lines and improve the attendee experience. Traditional paper-based or slow digital check-in systems created bottlenecks that frustrated both organizers and attendees.
Research & User Feedback
Through interviews with event organizers and attendee observations, we found that 85% of events experienced significant delays during check-in, with average wait times of 2-3 minutes per person. Users demanded a contactless solution that would work reliably even with poor internet connectivity.
