Standalone platforms that digitize and secure on-site visitor workflows — replacing paper sign-in with digital pre-registration, kiosk or tablet check-in, host notifications, badge printing, and audit-ready visitor logs. Core capabilities include visitor pre-registration and invite flows, customizable check-in screens (NDA signing, health attestations, photo capture), watchlist screening, host notification via SMS/email/Slack, emergency roll-call and evacuation lists, multi-location management, and compliance document collection for regulated environments (ITAR, HIPAA, C-TPAT). The category serves organizations where visitor tracking and screening are operational or compliance requirements — corporate offices, hospitals, schools, manufacturing plants, and gated facilities. It spans standalone tools (SwipedOn, Proxyclick/Eptura, WhosOnLocation, The Receptionist) distinct from visitor modules bundled inside broader workplace platforms.
