Readerless NFC mobile access credential software: The alternative to mobile wallet based NFC access control

Organizations large and small are transitioning to readerless NFC mobile access credentials to increase efficiencies in the credential provisioning process, adhere to NIST cybersecurity standards, and create a seamless experience at the door and streamline workflows.

Here are 5 reasons why you should choose readerless NFC mobile access credentials over Wallet app NFC door credentials.

1. Total Cost of Ownership (TCO)

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

Readerless NFC mobile access control reverses traditional mobile access control architecture. By using 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 readerless mobile NFC access control, only one integration is required to provide cross platform NFC mobile access for iOS and Android users.

No Physical Access Control System Integration Costs:

With readerless NFC mobile access software you don’t face any integration costs for your existing access control system. If your system(s) is on our list of PACS 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 software solution that adopts elliptical curves to store and secure your data. Our mobile credential 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, NASA 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 mobile NFC-enabled reader, the user’s smartphone. Therefore you don’t need to “rip and replace” with the latest reader upgrade solution. With the active NFC 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. Readerless mobile access credentials ensure 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 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’s readerless mobile access credential software, can interface with 20+ physical access control systems, regardless of their age to provide NFC mobile access. With Sentry’s latest full platform SDK integration, PACS can have readerless mobile credentials managed within their own platform just like their exisiting physical access credentials. On the other hand, 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’s readerless NFC mobile access open source SDK, powered by Doordeck, has the capability to integrate NFC 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

Sentry’s readerless mobile NFC access credentials are compatible with a combination of access control system brands. One readerless mobile credential 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 readerless NFC mobile credentials across your entire enterprise in minutes, all from your smartphone.

It’s simple to book and pay for the space as and when I need it. All I need is my smartphone to unlock the office door for the time I’ve paid for”.
EliseCRO Specialist at Swift Monkey
