NFC security explained: Are NFC tags safe for security operations?

The global NFC market is anticipated to grow from USD 21.69 billion in 2024 to USD 30.55 billion by 2029, recording a CAGR of 7.1% during the forecast period. 

Meanwhile, workplace expectations are evolving and threats are more dynamic than ever, security in commercial real estate (CRE) is undergoing a quiet revolution. The old model-static CCTV cameras, siloed teams, and a few staff managing access from a reception desk-is no longer enough. 

Enter NFC security: a powerful, touchless technology already embedded in our smartphones, bank cards, and transport passes. What began as a convenience tool is now becoming the gold standard for real-time, intelligent security infrastructure in the built environment. 

Is NFC secure?

The short answer; YES! But only when it’s implemented correctly with Trusted NFC tags.

At a technical level, NFC (Near Field Communication) is inherently more secure than alternatives like QR codes or Bluetooth. It requires close physical proximity (typically a few centimetres), which reduces the risk of remote interception. But that doesn’t mean all NFC deployments are secure.

In reality, the security of NFC depends entirely on how the tags and data are configured and types of NFC tags used.

Security can no longer be an isolated department. It needs to be embedded across property operations, informed by data, and responsive in real time. 

This is where NFC security shines. 

What is NFC technology and why does it matter?

Near Field Communication (NFC) is a short-range wireless technology that enables secure communication between two devices-typically, a smartphone and a reader when they are within a few centimetres of each other. 

Specifically in CRE, that means: 

• Touchless entry and exit 
• NFC proof of presence for mobile staff 
• Instant emergency notifications and alerts 

Moreover, unlike legacy access cards, Kinexio’s trusted NFC tags can’t be easily cloned or lost. It’s personal, encrypted, and highly configurable-making it a much smarter tool for modern-day risk management.

Here’s how: 

• Granular Access Control: Limit access based on role, time, or location-for example, ensuring cleaning crews can only enter designated zones after hours. 
• Real-Time Alerts: Automatically notify managers of unauthorised access attempts or when doors are left open. 
• Occupancy Insights: Track foot traffic and space utilisation to inform staffing and layout decisions. 
• Audit Trails: Produce instant reports for compliance, insurance, or incident investigations. 

Making property security everyone’s job 

Martyn’s Law is set to fundamentally change how public-facing buildings including shopping centres, arenas, and large offices prepare for security risks. But regulation aside, the need for connected response systems has never been more urgent. 

For context, in the U.S. alone, According to Reuters, as of March 2025 the FBI was overseeing approximately 2,700 active domestic terrorism investigations, nearly double the number since 2020 

The role of NFC technology in modern security

In the past, a small security team was responsible for managing large, complex assets often with limited visibility and support. NFC technology flips that model on its head. 

With an NFC-based communications platform, every team member on-site becomes part of the safety network: 

• Users can log suspicious activity. 
• Security and cleaning staff can report hazards or access incidents. 
• Tenants receive instant alerts on their devices during emergencies. 

It’s not just about access, it’s about engagement. Everyone becomes “eyes and ears,” enabling faster, more coordinated responses to threats. 

Smarter staffing = safer buildings

NFC technology doesn’t just enhance security, it optimises operational efficiency across your building. 

• Check-in data with NFC proof of presence helps fine-tune lone worker safety
• Geo-tagged incident reports highlight repeat issues or locations that need design or policy changes. 
• Touchless checkpoints verify that patrols are completed and cleaners have visited the right areas. 

Ultimately, this kind of visibility helps property managers run leaner, safer operations, with better oversight and fewer blind spots. 

NFC tech is here, today

As AI, IoT, and automation reshape the built environment, smart access control is no longer a “nice to have.” It’s a foundation. NFC provides a plug-and-play platform for future integrations whether it’s facial recognition, energy-saving automation, NFC asset tracking or predictive analytics. 

Moreover, as tenant expectations shift toward frictionless, tech-enabled environments, landlords who adopt NFC-based systems today are positioning themselves as leaders in innovation, safety, and experience.
