At the TechCrunch Disrupt conference, organizers sought to enhance the traditional event check-in process by utilizing a combination of Luma for guest pre-registration and a custom ReactJS app with Descope Flows for validating guest identities via email. This approach allowed for the automatic printing of name tags only for validated attendees, avoiding waste and ensuring a smooth check-in experience. Despite challenges such as late registrations and the technical intricacies of label printing, these were overcome with custom solutions including a Python script for seamless name tag printing and integrations with CRM tools like Segment and HubSpot. This innovative system illustrates how Descope Flows can streamline complex user journeys by integrating third-party systems without repeatedly modifying application code, ultimately providing a more efficient and personalized event experience.
