Mobile credentials are changing the way people move through buildings – and the lobby turnstile is where that shift becomes most visible. In this post, we break down how mobile access works with optical turnstiles, what to look for in a deployment, and why the combination of smart hardware and smart credentials matters more than ever. We've also brought in our technology partner, SwiftConnect, provider of the connected access network for places and spaces, to answer the questions we hear most from facility managers and security directors considering a mobile credential rollout.
For decades, getting into a secure building meant carrying something – a badge, a key card, a fob. Today, nearly everyone already carries a device capable of granting access to a secure building: a smartphone.
With the prevalence of smartphones, mobile credentials have moved from novelty to mainstream across commercial real estate, corporate campuses, healthcare facilities, universities, and government buildings. As organizations modernize their access control ecosystems, one question keeps coming up: How do mobile credentials actually work with optical turnstiles?
The answer involves a few layers of technology – and understanding them helps facility managers, security directors, and integrators make smarter deployment decisions.
A mobile credential is a digital access token stored on a smartphone (or wearable) that communicates with the access control system (ACS) via a reader to authenticate a user's identity and grant or deny entry. Rather than encoding access permissions onto a physical card, those permissions live in a secure digital wallet – typically managed through a mobile app or platform and communication using Near Field Communication (NFC), Bluetooth Low Energy (BLE) or Wi-Fi. This blog highlights the NFC solution and NFC-enabled wallets in Apple and Android devices.
Today, NFC has become the de facto standard for mobile access for the same reason it became the standard for mobile payments. People intuitively know how to use the tap gesture in daily life, at transit gates, coffee counters, and hotel check-in, which means extending it to the workplace is a natural next step. It simply requires the user to present their phone to a reader and it is supported by the Apple and Android devices people already use. Apple's Express Mode also extends NFC reliability since the access credential still functions when the phone is locked or nearly out of charge, exceeding legacy use cases.
When it comes to readers, often organizations specify multi-technology readers that handle legacy card formats as well as NFC, which keeps the transition to mobile manageable and does not require a hardware swap as the credential mix shifts.
An optical turnstile is the physical enforcement point. It's where split-second decisions from the ACS become physical reality – barrier open, or barrier closed.
Fastlane® turnstiles from Smarter Security® are designed to integrate with virtually any ACS via a Wiegand interface, and our pedestals are engineered to discreetly and cleanly accommodate third-party readers. That flexibility is what makes mobile credential deployments so seamless: the reader mounts directly onto or into the turnstile pedestal, and the credential handshake happens before the user ever reaches the barrier.
Here's the general flow:
That last point is important: the turnstile's intelligence operates separately from the credential type. The Fastlane optical sensor intelligent technology is doing its job – detecting tailgating, piggybacking, and other unauthorized entry attempts.
Successful mobile access deployments across commercial real estate and enterprise tenant organizations share common considerations that come up consistently during implementation. Here's what to prioritize:
One misconception about mobile credentials is that they somehow solve tailgating. They don't – and they don't need to. That's the turnstile's job.
Mobile credentials authenticate who is presenting access. The optical turnstile monitors how many people are moving through the lane. These are separate functions that work together. A valid credential opens the barrier; the turnstile's optical detection ensures only one person passes per authorization event.
This division of responsibility is a feature of well-designed entrance control systems, not a gap – and it's exactly how Fastlane turnstiles are built. Our neutral network-powered detection achieves less than ¼" tailgate accuracy on most models, processes up to 60 people per minute, and performs the same way regardless of what credential opened the lane.
As organizations increasingly deploy ADA-compliant and wider-lane configurations – like the Fastlane Glassgate 155 or Glassgate 400 Plus, with lane widths up to 47.24" – mobile credential readers need to be thoughtfully positioned to remain intuitive for users of all abilities.
Wider lanes can be more tempting to intruders – but our Sidegate Detection® technology addresses that head-on. This industry-first capability, exclusive to Fastlane turnstiles, identifies two individuals attempting to pass side by side through a single lane, stopping unauthorized entry in its tracks. And like all our advanced detection capabilities, it works the same way regardless of what credential opened the lane.
We asked the team at SwiftConnect, leading provider of the connected access network for places and spaces, to answer the questions facility managers ask most when evaluating a mobile credential deployment.
For someone who's never deployed mobile credentials before, how would you describe the end-user experience?
For most users, the experience at the lobby turnstile feels like nothing at all, which is exactly the point. Their credential lives in Apple Wallet or Google Wallet, the same place they keep their boarding pass or a payment card. There is no separate app to launch and no Bluetooth to manage. As the user approaches the reader, they simply present their phone to the turnstile reader – the interaction is closer to tapping to pay than to anything that feels like a security system. That effortless experience at the first access point, the lobby, sets the tone for every door, floor, and shared space beyond it. SwiftConnect's connected access network is designed to enable that fluid Street-to-Seat® experience consistently, from building entry to the tenant offices.
What ACS does SwiftConnect integrate with, and how does that integration work at a high level?
SwiftConnect's platform is vendor-neutral by design so it integrates with the ACS already in place, including LenelS2, Genetec, Software House, Honeywell, Brivo, AMAG, and others, without requiring organizations to replace working infrastructure. The platform sits above the existing ACS as the connected access network layer, handling identity management, credential delivery, and lifecycle automation. For a building where Fastlane turnstiles are already installed and integrated with a specific or multiple ACS, SwiftConnect connects the system(s) with the goal to add a modern credential experience to what's already there, versus replace it.
How does SwiftConnect handle credential issuance and revocation? For example, if an employee leaves, how quickly can their mobile credential be deactivated?
SwiftConnect enables fully automated badge provisioning with on-demand and self-service capabilities, connecting the organization's identity and HR systems to the access control infrastructure so that credentialing happens automatically rather than through manual administration. A new employee can receive access to their wallet before day one without a desk visit or badge pickup. When someone's role changes or they leave, administrators can instantly update or revoke permissions through the platform, and that change propagates to the ACS immediately. What SwiftConnect provides is the connective integration layer that makes all of this possible to deliver operational efficiency at scale.
Multi-tenant commercial buildings present unique challenges – multiple employers, varying ACS, shared lobbies and amenities. How does SwiftConnect handle that complexity?
Multi-tenant environments are one of the core use cases for the SwiftConnect connected access network. For example, in a typical multi-tenant building, the landlord controls base-building access, the lobby turnstile, elevators, and shared amenities. Each tenant controls their own floor and offices, often using a different ACS. The SwiftConnect platform brings together both the base-building and tenant access control infrastructures to create a single credential for a Streat-to-Seat® journey. In this instance, a tenant can use their mobile badge in the parking garage, at the lobby turnstile, elevator, and their offices. The landlord and tenant each maintain their own administrative control, while the tenant can move through the building without friction.
What are the barriers to mobile access adoption?
The biggest barriers to mobile access adoption tend to be less technical and more organizational and mindset-driven. For example, many organizations talk about hesitancy around cloud-based systems because the on-premise approach had been the access control standard for decades. This is still the case, even when most of an organization's other critical systems already live in the cloud.
Part of closing this gap in mindset means connecting access control to the identity and business systems organizations already run on. Physical and digital security are converging, with building access increasingly sitting alongside IT systems and identity infrastructure. Facility managers positioning themselves well are those already looking beyond who gets through a door to consider how physical identity and access connect across their entire organization.
Where do you see mobile credential technology headed over the next two to three years? What are the barriers to mobile access adoption, and what should facility managers be thinking about now?
Mobile credential usage has increased nearly tenfold in the past two years, yet the transition is still aspirational for many organizations while they deal with manual processes that continually create onboarding delays and security risks. Facility managers evaluating mobile access are also finding themselves navigating a shift in who else is involved in the buying decisions. IT and CISOs are increasingly coming in with questions around identity provider integration, SOC 2 compliance, data residency, and API governance, and being able to speak to those requirements is becoming part of building the internal case.
Mobile credentials and optical turnstiles are a natural pairing – one handles the identity layer, the other handles the physical enforcement layer. When both are properly specified and deployed, the result is a lobby experience that's faster, more convenient, and more secure than traditional card-based access.
Fastlane turnstiles are built to support this kind of layered security ecosystem. Our open integration architecture means organizations aren't locked into a single credential technology – they can evolve their access strategy over time without replacing their turnstile hardware.
