Sentry Mobile Access: The Alternative to Mobile Wallet App Credentials

Organizations large and small are transitioning to Sentry Mobile Access to increase efficiencies in the credential provisioning process, create a seamless experience at the door and streamline workflows.

Here are 5 reasons why you should choose the Sentry Mobile Access credentials vs wallet app NFC door credentials providers.

1. Total Cost of Ownership (TCO)

No “rip and replace” access control reader hardware upgrade costs:

As Sentry Mobile Access is reader-less and uses the user’s smartphone as the active NFC mobile reader, there’s no need to upgrade your existing readers. Save money associated with new reader hardware upgrades and labor costs.

No contractual annual wallet app license fees:

Wallet app credential licenses run off a cost per user per year model in addition to the integration and maintenance costs. With Sentry Mobile Access, only one integration is required to provide cross platform NFC mobile access for iOS and Android users.

No Access Control System Integration Costs:

With Sentry Mobile Access you don’t face any cost to integrate our software with your existing access control system, so there’s no custom integration cost. If your system(s) are on our list of integrations, we can add our retrofit mobile access software to it in minutes.

2. Security

The only NIST compliant access control solution

We are the only NIST compliant access control solution that adopts elliptical curves to store and secure your data. Our encryption architecture is years ahead and even quantum computing can’t crack it. All our customers’ data is encrypted at rest using the highest military grade standards in encryption architecture. The National Institute of Standards and Technology (NIST) standards we adopt comply with what the US military, NSA and White House use as a benchmark.

The only solution where the smartphone is the biometric 2FA NFC enabled reader

We use NFC technology that is built into iOS and Android smartphones and leverage the power of biometric and multi-factor smartphone security. We’ve created the first active NFC enabled reader, which is actually the user’s smartphone. Therefore you don’t need to “rip and replace” with the latest reader upgrade solution. With our reader being the user’s smartphone we ensure extra layers of security that traditional readers cannot provide for mobile credential wallet integration.

Geofencing, time and IP access restrictions

Restrict user access permissions based on time, IP address and geofencing. Prevent unauthorized out of hours access. Geofencing restrictions can be set for remote access, preventing unlocks from certain radius’. IP restriction allows you to control access depending on the network used e.g. you can set access to only be available on a particular wifi network.

3. User Experience

Streamline with cross platform credential provisioning and workflow efficiencies

End users have a seamless user experience whether they are an Android or iOS user, through non wallet-based NFC mobile credentials. Whilst companies benefit from a scalable mobile access software-based solution to augment their current security systems for NIST compliance. Sentry Mobile Access ensures a consistent and user-friendly experience, while also facilitating easy and cost effective integration and setup. Achieve platform consistency with Sentry’s interoperable mobile NFC credentials. With one platform for iOS and Android users.

Unify multiple access control systems of any age under one application

One digital key to access a portfolio of buildings and access control systems with a ‘single pane of glass’ solution for both iOS and Android users. Provision a permanent or temporary mobile pass in minutes, eliminating cost and multiple workflow steps, to help provide a seamless user experience. Our NFC mobile credential interoperability provides the ability to unify access and management. One virtual key can be used to access a portfolio of buildings and doors, even if they have different disparate access control systems installed.

NFC mobile credentials and visitor virtual keys via open SDK for building and PropTech applications.

Customize access control user levels and experience with mobile credentials and virtual visitor keys via our app or 3rd party building or PropTech applications. Our open SDK software allows you to integrate our NFC access control solution into building and tenant experience apps. Tenants can use their existing building app to open doors with their smartphone’s NFC technology.

4. Visitor Virtual Keys

Seamless visitor experience at the door with time-limited virtual keys

Admins can share time sensitive virtual keys with visitors, contractors, or out of hours staff. After the time is up, access permissions are automatically revoked, securing the building. Visitor passes can be issued using an email. Remotely via the mobile or web app straight to the user’s smartphone.

Visitors don’t need to download an app for building access via virtual keys

Share app-less visitor passes. Visitors can access their virtual keys in their email. A link to a QR code scanner can then be used to scan the QR code on the door credential to enter a door securely.

Send up to 1000 digital visitor passes at one time

Up to 1000 emails can be sent as visitor passes at one time. Perfect for large events, where large quantities of attendees require access for a specific time frame.

5. Interoperability

Integrates with major access control systems of all ages not just the latest NFC enabled generation

Sentry Mobile Access can integrate with 20+ access control system brands, regardless of their age to provide NFC mobile access. NFC wallet app credentials require the latest reader hardware to be installed, meaning costly rip and replace can be required.

Integrates into 3rd party platforms via open SDK

The Sentry Mobile Access open source SDK, powered by Doordeck, has the capability to integrate mobile access with PropTech technology, from unlocking doors to activating building iOT sensors. Our software is flexible to accommodate and unify a combination of technologies.

Unifies a combination of access control system brands under one centralized platform

The Sentry Mobile Access open API can unify a combination of access control system brands. One Sentry Mobile Access virtual key can unlock multiple buildings with different systems, depending on access permissions. Building management can control access to a portfolio of buildings with disparate systems, just as easily as one.Furthermore our mobile NFC credentials are designed to work alongside traditional keycard, badge, or fob entry methods so there is no need to choose just one way forward or to “rip and replace”.

We are the only mobile credential solution that uses NFC technology to unlock doors outside of smartphone wallet apps. Retrofit your access control experience with NFC mobile credentials across your entire enterprise in minutes, all from your smartphone.
