Sine review
A flexible visitor system combining kiosk, mobile, geofenced, and emergency workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Sine is a visitor and contractor management system for workplaces managing visitors, contractors, staff, and workplace access. It supports iPad kiosk check-in, reception workflows, mobile check-in through Sine Pro, and geofence-based automatic check-in and check-out. Invitations and pre-registration help hosts prepare for arrivals, while visitor photo capture, face checks, U.S. driver's-license scanning, badge printing, and notifications support identity and reception workflows. The platform also covers reporting, live visitor activity, roll calls, and evacuation checks, making it suitable for organizations with both daily reception needs and workplace safety procedures.
Sine's plan structure scales capabilities across Small, Medium, Large, and Enterprise tiers. Small includes basic visitor management features. Medium adds native Active Directory and SAML SSO, while Large also adds a native Outlook plugin. Enterprise is intended for larger rollouts and includes custom InfoSec documentation. A 30-day trial is available, but there is no free plan. This structure makes Sine a stronger fit for teams that need directory, single sign-on, or Outlook connectivity as their deployment grows, while smaller teams may find the paid-only model less suitable for lightweight use.
The platform's ecosystem includes Microsoft Teams, Slack, Microsoft Outlook, Microsoft Entra ID, SAML SSO, webhooks, Eventbrite, Gallagher, Inner Range, Honeywell EBI, and Aruba. Its web, iOS, Android, and API support gives organizations several ways to connect check-in with workplace and security workflows. The main trade-off is that some enterprise-oriented capabilities are tier-dependent, and ID scanning is focused on U.S. driver's licenses. Choose Sine for multi-mode check-in, geofencing, identity workflows, and emergency accountability; consider another option if you need a free plan or broader documented ID coverage.
