Overview
This guide is designed for you to provide a full overview of Sentry Interactive’s readerless
mobile credential SDK into your existing access control platform and unlock the untapped
recurring revenue potential of your legacy access control system install base.
With increasing pressure on access control OEMs and integrators to deliver smarter, more
sustainable, and user-friendly building experiences, our SDK provides a cost-effective,
scalable and software-only path to mobile NFC access, with no need for expensive
hardware retrofits or costly licensing fees.
Discover how Sentry Interactive helps you to potentially turn every existing customer into a
revenue opportunity while positioning your solution at the forefront of innovation as a
software enhancement that is exclusively available only to OEMs.
Every existing customer is a prospect
Your legacy customer base represents one of your greatest untapped revenue growth
opportunities with minimal financial investment required.
By reconnecting with these customers, you can offer them a modern NFC mobile access
solution that:
- Is the only fully readerless solution on the market offered to OEMs.
- Offers best-in-class user experience at the lowest total cost of ownership.
- Can be deployed and updated remotely, reducing on-site service needs.
- Regain control of your customer, channel and the revenue you’ve been losing.
With Sentry Interactive’s SDK, legacy systems become upgradable through software alone,
giving you an easy, low-friction path to retain, upsell and grow recurring revenue.
Unlock recurring revenue with a readerless upgrade
Legacy access control systems typically rely on large, one-time hardware investments.
Sentry Interactive enables you to easily shift from a CapEx model to a SaaS revenue model,
by offering user-based mobile credentials.
- No physical readers required, reduce installation friction and hardware costs.
- Remote deployment and updates, reducing on-site servicing needs.
- Lower operational integrator support costs and increased upsell potential.
- Additional revenues for integrators through providing a unique offering.
This recurring revenue model not only improves your long-term margins, it also strengthens
long-term relationships with your customer base.
Independent from Wallet
Many credentialing platforms are locked into proprietary ecosystems, requiring Wallet and
third-party app integrations, ongoing licensing costs, and restrictive iOS / Android
dependencies.
With Sentry Interactive, you get:
- A non-proprietary SDK built only for access control OEMs.
- No dependency on Apple Wallet or Google Wallet.
- Zero integration fees or platform lock-in.
- Full control of your customer experience within your own platform and application.
- Regain control of your customer, the channel and the revenue you’ve been losing.
This empowers you to deliver a seamless mobile access solution without introducing new
complexity, cost, or external vendor license fees.
Provide Higher Customer Lifetime Value
Customers with legacy access control systems are increasingly seeking ways to modernize
access control without entirely replacing their infrastructure.
With our SDK, you can offer:
- A scalable and secure upgrade path without replacing hardware.
- Readerless technology that uses NFC mobile credentialing with minimal disruption.
- A cost-effective alternative to traditional keycard-based access.
This not only improves security and usability — it significantly boosts Customer Lifetime
Value by making it easier to retain, expand, and support your install base with an added
value proposition.
Offer a Sustainable, Scalable Alternative to ‘Rip and Replace’
Replacing legacy hardware can be disruptive, expensive, and wasteful. Our readerless SDK
integration empowers you to deliver immediate value without physical infrastructure
changes.
- Minimize electronic waste and carbon footprint.
- Extend the life span of existing access control system infrastructure.
- Deploy quickly without downtime or construction.
- Scale across multiple locations with zero added hardware.
This sustainable approach also supports growing carbon neutral ESG mandates for
commercial real estate, government buildings, healthcare facilities and university campuses.
Deliver Premium User Experience
Today’s tenants, employees, and visitors expect convenience, speed, and seamless
integration in their building experience applications.
By offering Sentry Interactive’s mobile credentialing:
- Users access doors, elevators, and amenities directly from their smartphones.
- No more lost keycards or front desk delays.
- Access is simple, secure and intuitive.
Our SDK integrates directly into your customers’ existing workplace, tenant, and visitor
applications, providing a frictionless user experience that drives satisfaction and operational
efficiency.
Add Value Within Apps Your Customers Already Use
Your customers have already invested in building apps for workplace management, tenant
engagement, or smart facilities. Our SDK is designed to plug directly into these third-party
apps, extending their capabilities with secure mobile access.
This means:
- No new app for users to download.
- Brand-consistent access experiences.
- Increased engagement within existing platforms.
- Seamless interoperability with third-party systems (e.g., visitor management, HR and identity management, etc).
This approach not only saves time and cost but reinforces the value of readerless mobile
credentials across the building’s ecosystem.

Sentry Interactive has developed the only interoperable mobile credential SDK that
provides a readerless transition to NFC mobile access designed for market-leading system
manufacturers. We’re enabling access control platforms to lead the next wave of innovation,
without needing to reinvent their systems or invest heavily in developer resource.
Benefits include:
- Competitive differentiation with cutting-edge, reader-free access.
- Expanded reach for OEMs into new verticals (flex and coworking, multifamily, healthcare, education etc.)
- Greater customer retention by modernizing legacy deployments.
- Increased appeal to new prospects and retrofit projects.
Position yourself as a future-focused provider with scalable, software-driven access control.
Pioneer NIST Compliant Mobile Credentials
Security threats to physical credentials continue to grow, including card cloning, credential
sharing, loss and theft.
Sentry Interactive offers:
- NIST compliant mobile credentials where the phone is the reader and credential holder.
- Secure communication via readerless NFC technology with cryptographic
- authentication.
- Elimination of keycard vulnerabilities as readerless mobile credentials are protected from cloning, sharing, or loss.
- Phones are constantly upgraded with the latest security updates while card-based systems are outdated and can become a security liability.
Upgrade your customers to a more secure and modern access experience and align with
evolving compliance and cybersecurity standards.
Streamline Operations Through Smart Automation
Physical keycards and outdated access workflows lead to operational inefficiencies. With
our SDK integration with identity and access management systems, you can bring intelligent
automation to access control:
- Auto-issue credentials based on HR, identity or workplace system rules.
- Self-service access for employees and guests.
- Reduce front desk workload and support tickets and requests.
- Provide cloud-based visibility and remote control.
This helps customers save time, reduce admin costs, and create a frictionless building
experience.
