What is NFC mobile credential interoperability?

Looking to transition to mobile credentials but are wondering what all the talk about interoperability is?

Let us explain…

You have an access control system already installed in your building that uses physical key cards for door entry. 

You might even have a combination of different access controllers or readers that you didn’t already know about.

Your first thought when looking to transition to mobile credentials is probably the need to upgrade your reader hardware to accommodate NFC mobile access. The high costs, disruption to hardware, and length of turnaround time is enough to put you off upgrading and ultimately continue on using your trusty key card entry systems.

But what about a software solution that can integrate into all these existing systems you have installed to unlock the ability to use your mobile as a credential. Installation can be done remotely via cloud infrastructure without having to rip and replace hardware.

This is an example of an interoperable mobile access solution. An open system that has the ability to integrate with multiple different hardware systems and software applications to enable unified mobile credential access. 

Providing users the choice to use their mobile for convenient contactless access without being limited to one system provider.

It is a SaaS solution that prevents lock-in to ‘trusted’ access control system providers that require expensive system upgrades that enable mobile credentials limited to one system. 

I want my mobile credentials to be NFC enabled, are the new mobile wallet credential solutions the only choice?

No. Plus there are restrictions with interoperable mobile NFC wallet credentials. Apple and Google wallet mobile credentials can only be read by new age access control readers. Therefore, if you have pre 2017 readers installed in your building it’s most likely that you will have to rip, replace and upgrade reader hardware. 

The Sentry Mobile Access solution is a smart mobile credential platform that is open to work with any major access control system, regardless of its age, minimizing the need to replace any hardware.

Offering a choice to the user, to use a single mobile NFC credential as well as their existing key cards to access multiple entrances, plus avoid the need to carry multiple physical or mobile credentials in their wallet.

Sentry Mobile Access, powered by Doordeck, is a proprietary NFC mobile credential application outside of Apple and Google wallet. Therefore, with one integration your tenants and visitors, despite which device they use, all have the same capability to use their mobile as a credential, to access your building. Users can use their mobile’s NFC technology to unlock a door or otherwise use our Android and Apple widget for contactless access.  

Contactless mobile visitor credentials can also be shared remotely to contractors and guests and can be set for a specific time period. During the time set the mobile credentials are activated and the doors granted to the visitor can be accessed via their NFC mobile credential. 

Does the interoperability of Sentry’s mobile credentials stretch to tenant experience apps?

Yes, the Sentry Mobile Access SDK can integrate with your building app to expand its capabilities to hold smart mobile credentials that your users can use to access all doors in a building they have been granted access to.
