Fast track mobile credential deployment, remove reader hardware dependency
Add a mobile credential software layer to your existing access control system. Keep your current readers and panels, the mobile phone is the reader and the credential.
Modernize and unify existing PACS
Readerless mobile credentials can integrate with and unify access across 20+ physical access control systems. There’s no integration costs or extra licensing fees. Our software simply adds a mobile credential layer within the existing system installed.
Keep your existing panels and readers
Add an NFC mobile credential layer to your existing access control systems including proximity-based systems. No reader hardware is necessary, just a wireless, powerless and battery-free Sentry Smart Access Tile placed next to the doors you want to activate mobile access on. Avoid delays and costs associated with reader hardware.
Keep your existing readers. Add mobile access credentials.
Enjoy a cost-effective software based transition to advanced readerless NFC mobile access, without any disruption to your legacy access control system.
Readerless
Mobile credentials don’t require reader hardware to operate, therefore no reader hardware upgrades or rip and replace is necessary to integrate with your legacy access control system.
Interoperable
Our open SDK is designed to integrate with multiple major access control systems in addition to a portfolio of third-party space management and tenant experience applications.
Scalable
Mobile credentials can be setup and rolled out remotely in minutes and not days, with no disruption to existing access control system infrastructure.
Secure
The only NIST compliant NFC mobile access credential SDK that delivers the highest banking level encryption. Time, geofence and IP restrictions available.
Readerless mobile credential features:
- NFC tap-to-unlock or QR code scan access technology
- Remote door access via iOS or Android widgets
- Digital key sharing of time sensitive mobile credentials
- Time, Geofencing, and IP access security restrictions
- Compatible with iOS and Android
- Adheres to NIST Cybersecurity Framework 2.0
- Asymmetric cryptography and Zero Trust
- Built with open standards
- Managed in the Sentry Interactive Platform or your own
- Stored in our Mobile App or yours via our SDK
Generate an ROI with reassignable mobile credentials for temporary access
Want to reassign a temporary mobile credential to another visitor without an extra charge?
Our temporary digital visitor passes are built with reusable access capacity. This means you only need to purchase how many mobile credentials you need at peak visitor capacity, rather than total visits. This provides a much more economical approach to issuing mobile credentials for temporary visitors, contractors, or shift workers.
See how much you could save by serving peak visitor capacity rather than total visits.

Prices are illustrative. Enter your own figures for an accurate comparison.
You serve 25,000 identities a year. Why pay for 25,000 credentials?
At peak, only 100 need to be active at once.
New single-use mobile credential per visitor
Reassignable readerless mobile credentials
Peak demand is higher than annual identities. Check your figures.
Embed mobile access into your existing building app
Our Sentry Mobile Access SDK integrates with third party applications to manage all buildings effortlessly. No matter the size or sector; from building and facilities management apps, to club, hospitality, and coworking and visitor management apps, our SDK increase its capabilities to mobile access credentials.
We credential the door and use the mobile phone as a virtual reader
Sentry Smart Access Tiles require no batteries or power are simply applied next to doors and linked with the cloud via the QR code. Setup is remote to enable, fast, reliable, and secure smartphone NFC door entry in no time, without compromising security.
Built on the highest security standards
Sentry Interactive’s NFC mobile access credentials are engineered for comprehensive security. We are the only mobile credential SDK provider to follow NIST compliant standards by using the smartphone as the reader. Military-grade encryption protects user access data in the cloud, while audit logging and privacy regulation compliance further secure the data.

Need enterprise-scale asymmetric credential enrollment?
Open credential mass enrollment service
Our new SDK offers mass enrollment capabilities for asymmetric physical and mobile credentials, such as Public Key Open Credential (PKOC). This means by embedding our SDK with your compatible access control system, you can enroll public-key credentials at scale to your users across multiple locations from a centralized system, that will work with compatible reader hardware.
Find out how our mobile credentials deliver to PKOC specifications, pioneering the future of open standard credentials.
Check out our short guide to PKOC and how enterprises can start rolling it out at scale and what they need to do so.
Find out what PKOC is and how it is shaping the future of open standard credentials that deliver the highest security levels.
Understand how and why we have protected our mobile access credentials with asymmetric cryptography, in line with PKOC.
Learn more about the possibilities of non proprietary, open standard, mobile credentials, built on PKOC specification.
Frequently asked questions
Sentry Interactive is a software development company that provides a software-only upgrade that adds NFC mobile credentials to existing access control systems. It allows tenants, employees, and members to use their smartphone to unlock doors across multiple facilities and systems, without requiring any new reader hardware to be installed.
No. Sentry Interactive’s mobile credential software does not rely on upgrading your existing door reader hardware, your existing BLE or proximity card readers can stay in place. The smartphone acts as both the reader and the credential, meaning there is no rip and replace of hardware, no rewiring, and no disruption to your current access control infrastructure.
Sentry Interactive is the only mobile credential SDK provider to follow NIST-compliant standards by using the smartphone as the NFC reader. The software uses asymmetric encryption to protect access data in the cloud and secure key sharing. The mobile credentials also support time-based, geofence, and IP restrictions, and maintain full audit logging of unlock data. It is also PCI DSS compliant and Cyber Essentials certified.
Mobile credentials can be set up and rolled out remotely in days rather than weeks or months. The battery-free Smart Access Tiles are placed next to doors and linked to the cloud via QR code, with no rewiring or installation works required. From initial contact, the team aims to connect within 24 hours, conduct a system audit, and have mobile credentials active within days.
By embedding Sentry Interactive’s SDK, organizations can enroll users at scale with mobile and physical credentials built to PKOC specification. The SDK enables remote, bulk issuance of PKOC-compliant credentials without manual, device-by-device setup, turning what was traditionally a time-consuming process into a fast, scalable rollout across an entire workforce or user base.
