Store readerless mobile credentials in your platform and synchronize unlocks with existing features

Increase platform usage and retention by adding value with a readerless mobile credential feature that works across multiple different access control systems and synchronizes with existing features in your platform. The SDK is free and open source and has pre-built integrations with 20+ access control systems. 

Platform feature enhancement

Add a feature customers need for physical access, and increase app usage and retention along with it. Synchronize mobile credential unlocks with existing platform features, like facility bookings, check-in, or data analytics, to deepen your existing feature set. Every access event is a timestamped, identity-linked data point your platform can use. An essential premium feature to layer on top of data you’re already collecting. Instant digital issuance and revocation means you can tie access directly to onboarding and offboarding events in real time. 

Collect additional recurring revenue

Unlock additional recurring revenue by charging a premium fee for the readerless mobile credential door unlocking feature, no new billing infrastructure to build. Per-credential, per-user pricing slots directly into the tiered SaaS pricing you already run, there’s no need to set up a separate commercial model. Offer it as part of a premium tier, or as an add-on. It bills the same way your platform already bills everything else, on the same cycle your customers already expect.

Skip building separate PACS integrations

Sentry’s readerless mobile credentials are already compatible with 20+ major access control systems so you avoid building and maintaining a separate integration for every access control system your customers have installed on site. In addition this means the feature can scale and work cleanly across a customer’s multi-site portfolio, since the credentials are built on open interoperability with multiple access control systems rather than a single vendor’s hardware.

How to get started

Integrate

Integrate the open-source SDK into your platform, in the language your stack already uses.

Enroll and issue

Your customers can enroll their users with mobile credentials directly via your platform, and issue or revoke access automatically by synchronizing access permissions with other platform features like facility booking, check-in, and more.

Bundle and scale

Bundle your new mobile access feature into your existing SaaS pricing tiers, and scale across every site your customers run. Working across 20+ PACS without building or maintaining a single additional integration.

Provide mobile credentials built different

Instant, remote revocation

Mobile credential access permissions can be granted or revoked automatically in real time, in line with the onboarding and offboarding events your platform already tracks.

One integration, access to multiple PACS

Through a single open integration you unlock mobile credentials stored within your platform that already work with 20+ major access control systems, including Paxton, Brivo, ZKTeco, C·CURE, Lenel, and Gallagher. Developer time is not necessary to build out separate integrations with each brand, fast tracking your clients transition to mobile door access.

Bypass reader hardware barriers

The user’s smartphone via your platform stores the credential and acts as the active reader. All that’s required at the door is a passive, wireless Sentry Smart Access Tile. No pulling cable, batteries, or charging is required.

Centralized, auditable access logs

Every unlock event; user, time, location is logged and available via the SDK, ready to feed into your own analytics or dashboards rather than living in a separate system.

Asymmetric cryptography, not shared secrets

Readerless mobile credentials use a public/private key pair. The public key verifies identity, the private key stays in the secure enclave of the user’s device. Every credential exchange is a fresh challenge-response handshake.

NIST-aligned and Zero Trust

Built to align with NIST cybersecurity standards and Zero Trust Architecture, no implicit trust based on location, network, or prior authentication. This means our credentials are never trusted just because it was accepted last time, or because it’s on a known network.

Per-user pricing slots into the subscription model you already run, so you can offer it as part of a premium tier or as an add-on and bill it on the same cycle as the rest of your platform, without new billing infrastructure.

 

Can access be synchronized with our platform's existing features?

 

Yes. Credential issuance and revocation can be tied to events you already track, like onboarding, offboarding, facility bookings, or check-in, so access updates happen automatically in real time.

 

What hardware is required at the door?

 

None beyond a passive, wireless Sentry Smart Access Tile. The user’s smartphone acts as the active reader via NFC tap or QR code, so there’s no cabling, batteries, or charging involved.
