What it is

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.

Sine in depth

Read the full write-up

Sine is a facilities platform for organizations that need to manage people entering their sites as well as contractor compliance. It is best suited to teams coordinating activity across multiple locations; its main trade-off is that paid plans use custom pricing based on check-in volume.

Overview

Sine brings visitor entry, contractor records and site activity into one service. Its dashboard gives facility teams a view of expected arrivals, people currently on site and searchable check-in history. That makes it a better fit for sites where contractors and visitors share an arrival process than for a reception desk that only needs a visitor log.

The product is part of Honeywell International’s Security and Access Solutions business and has roots in Adelaide, South Australia. Sine says it uses AWS infrastructure, encrypts data in transit, and conducts regular audits and penetration tests; it also states that it complies with GDPR requirements.

Key features

Visitor entry and contractor compliance

Sine Core supports customized check-in flows, electronic entry documents and branded kiosks. Invitations, FastTrack QR, host notifications and roll calls help structure arrivals and account for people on site. Visitor photo capture and emergency tools add practical support for sites that need to identify and locate visitors. Contractor onboarding covers inductions, permits, certifications and compliance records, so teams can manage credentials alongside entry rather than treating contractor administration as a separate task.

Mobile and integrations

Sine Pro supports nearby-site check-in through geofencing or QR codes, visitor notifications and mobile badge printing. These options suit sites where arrivals happen away from a fixed reception kiosk; they are less important to a single-site operation with a staffed front desk. Integrations include Microsoft Teams, Slack, Outlook, Entra ID, Eventbrite, Gallagher, Honeywell EBI, Cm3 and webhooks, giving Sine routes into communication, identity and access-control systems.

Workflows and safeguards

Sine Workflows is an add-on requiring a Sine Core plan, so it is not a standalone starting point. Enterprise customers can receive account setup, training, hardware and dedicated support; Sine also provides a help site. The support package is most relevant to organizations rolling out across buildings, while smaller teams may not need that level of assistance.

Pricing

Sine has no free plan for its broader platform, but the Sine Pro mobile app is free at free for visitor, contractor, staff and courier check-in on iPhone and Android. It is a useful no-cost entry point for mobile check-in, but it is not a substitute for the paid Core plans’ visitor-management package.

Small, Medium and Large plans have custom pricing. All are based on estimated check-in volume, include unlimited hosts, and apply a fair usage policy if usage exceeds the plan level. Small includes Core visitor management, self-serve kiosks, digital invitations and FastTrack QR, host notifications, roll calls and geofence check-in/out. It suits teams needing structured visitor entry, but lacks the additional capabilities in higher tiers.

Medium adds FastTrack pre-registration, an asset register and issuance, Entra ID sync, SAML SSO and an Outlook invitation add-in. It is the more appropriate step for organizations that need identity and asset workflows. Large adds a public API, real-time visitor screening, and access-control and SecureBridge options, making it the stronger fit for more connected or security-sensitive sites. Enterprise includes everything in Large, with tailored packaging for organizations onboarding 20 or more buildings and preferred pricing.

Small through Large plans start with a 30-day free trial. Afterward, Sine contacts the customer with billing information; organizations should confirm their eventual cost and expected-volume tier before adopting the service. There is no published price to compare across the paid plans.

Platforms

Sine supports Android, iOS, web and API access. The mobile app is available for iPhone and Android, while web and API support suit teams managing operations or integrations beyond mobile check-in.

Who it's for

Sine is aimed at organizations of any size, with particular relevance to facilities managing both visitors and contractors. Its combination of compliance records, site visibility and mobile entry is most valuable when people arrive across multiple sites or when contractor credentials are part of day-to-day access control. A small office seeking only a basic sign-in log may find its broader scope and volume-based paid plans unnecessary.

Pros and cons

Pros: Visitor entry and contractor compliance sit alongside a dashboard of expected arrivals and people on site, useful for facilities coordinating both groups.

Pros: Geofenced and QR check-in, mobile badge printing, and a broad integration list support distributed or connected operations.

Pros: Unlimited hosts avoid a per-host constraint, while the free mobile app offers a no-cost check-in option.

Cons: Paid plan prices are custom and volume-based, making budget comparison harder before contacting Sine.

Cons: Workflows requires Core, and the mobile app alone does not include the complete paid visitor-management offering.

Alternatives

For property teams comparing tools by operational focus, start with Property Management Vendor Management Software or Visitor Management Software. Choose Breezeway for Student Housing if a freemium property operations platform with cleaning scheduling and payments is the closer fit. Fyxt may suit teams looking for a freemium property and tenant-payment option. For credentialing specifically, RealPage Vendor Credentialing offers vendor credentialing and ongoing criteria checks, including a no-cost property-manager plan. SubDoc, TrackMyVendor, VendrVault, bcs and ComplyFlow are alternatives to compare for vendor or contractor management.

Verdict

Choose Sine when visitor entry, contractor compliance and site activity need to work together, particularly across multiple locations. Its range of check-in methods and integration options is the main reason to choose it; look elsewhere if you need a clearly priced paid plan or only a straightforward visitor log.

Verdict

Sine covers visitor arrivals, contractor compliance, and site activity, with mobile check-in options and a broad integration list.
