What is a passive NFC smart lock?

As a property manager, you know that access management is more than just a matter of convenience – it’s the foundation of tenant safety, satisfaction, and operational efficiency.

With the rise of smart technologies, passive NFC (Near Field Communication)-powered smart locks are emerging as a powerful and sustainable tool for modernizing access management in multifamily housing communities. 

How does NFC technology work? 

NFC is a short-range wireless technology that allows two devices to communicate when they are within a few centimeters of each other. You’re probably already using NFC technology without even noticing it – for example, when you make contactless payments with your smartphone. 

Unlike Bluetooth, which operates over longer distances and requires pairing, NFC is designed for quick, secure, and intentional interactions. This makes it ideal for access control, where precision and security are essential. You can read more about NFC technology and how it has revolutionized the smart-locking industry here

What types of NFC smart locks are there? 

A passive NFC smart lock is a battery-free electronic lock that harvests the energy it needs to operate directly from an NFC-enabled device – such as a smartphone – when it’s held against the lock. No external power source or batteries are needed in the lock itself. 

This is different from traditional battery-powered smart locks that simply use NFC as an authentication method. Passive NFC locks offer a more sustainable and maintenance-free alternative while delivering the same benefits of digital access. 

Companies such as iLOQ have pioneered this technology and have been at the forefront of mobile access solutions based on passive NFC power for nearly a decade. 

As well as the battery-powered locks that use NFC for authentication mentioned above, there are also cloud-connected systems with online management features and hybrid models that combine NFC with PIN codes or Bluetooth. 

Benefits of passive NFC smart locks in multifamily properties 

  1. Enhanced security 
    Passive NFC smart locks use encrypted communication and secure elements in smartphones or key fobs, making unauthorized copying or hacking extremely difficult. Unlike mechanical keys or shared PIN codes, each digital credential is unique and traceable. 
  1. Convenience for tenants 
    Tenants can use their smartphones to access apartments and common areas – there’s no need to carry or replace lost or stolen physical keys. Access can also be shared temporarily with guests or service providers such as cleaners. 
  1. Operational efficiency 
    Property managers can issue, update, or revoke access rights remotely – there’s no need for on-site visits or physical key handovers. Audit trails provide visibility into access activity, improving security and accountability. 
  1. Zero battery maintenance 
    Unlike traditional smart locks, passive NFC locks like iLOQ’s don’t require batteries in the lock. This means lower maintenance, fewer service calls, and greater long-term sustainability. 
  1. Cost savings 
    Reducing lost key costs, eliminating rekeying, minimizing on-site labor, and removing battery replacements lead to significant long-term savings.
