Sine
Sine provides visitor, contractor, staff, and compliance management for facilities. Sine Core supports customized check-in flows, electronic entry documents, and branded kiosks. Contractor tools cover onboarding, inductions, permits, certifications, and compliance records, while the activity dashboard shows expected arrivals, people on site, and searchable check-in history. The Sine Pro mobile app adds nearby-site check-in with geofencing, QR codes, visitor notifications, and mobile badge printing. Listed integrations include Microsoft Teams, Slack, Outlook, Entra ID, Eventbrite, Gallagher, Honeywell EBI, Cm3, and webhooks. Plans are based on estimated check-in volume, include unlimited hosts, and apply a fair usage policy if use exceeds the plan level. Small through Large plans start with a 30-day free trial; Sine contacts customers with billing information after it ends. The paid service has no free plan, though the Sine Pro mobile app is listed at free. Sine says it uses AWS infrastructure, encrypts data in transit, conducts regular audits and penetration tests, and complies with GDPR requirements.
