Five ways custom NFC is making the world smarter
From seamless, one-touch checkouts at the supermarket to tap-and-go travel on local transport, near-field communication (NFC) has quietly become the default technology for consumer payments, transit, or ID access. And yet, these applications only scratch the surface of what it can do.
Custom NFC – standard NFC combined with sense and compute capabilities – is expanding traditional applications and unlocking value in new and exciting places. And FlexICs – ultra-thin, physically flexible chips with a low carbon footprint – are pushing those boundaries still further, enabling a new generation of NFC connectivity at scale, at low cost and in a novel form factor.
Here are just five of the ways custom NFC is making an impact.
1. Smart packaging and consumables
Product packaging is no longer just a protective shell or a branding opportunity. Brands are already using NFC to build relationships beyond the shelf, offering content and services that surprise and delight, from special offers, usage tips and ‘Easter egg’ content to advanced product information. But custom NFC can take things to the next level.
For foodstuffs, NFC-enabled freshness sensors can track time, temperature or humidity, detecting changes in state that impact quality and freshness. These real-time insights prevent food waste, removing the need for unnecessarily short use-by dates, and giving consumers accurate information on the condition of their groceries.
For fine wines, sensors embedded near the cork can detect pressure or gas escape. Paired with NFC, a single tap of a smartphone can confirm whether the bottle was stored and sealed correctly, giving peace of mind for premium or collector bottles.
And for consumables, custom NFC can detect low product levels, issuing reminders that it’s time to re-order.
2. Tamper detection
Custom NFC also plays a part in tamper detection solutions, offering instant, intuitive verification with a simple smartphone tap. Integrated directly into packaging, it provides real-time, digital proof of product integrity, enhancing consumer trust and ensuring the integrity of each purchase.
Importantly, NFC tamper detection is discreetly embedded, so it doesn’t take up valuable real estate or reduce branding opportunities. It can’t be covered or replaced, and a unique ID prevents duplication or tampering. Crucially, the flexible form factor of FlexICs bring custom NFC functionality, even or curved surfaces – without the telltale ‘bump’ of silicon equivalents.
3. Hot/cold-chain monitoring
Safeguarding the integrity of temperature-sensitive goods is vital to ensure that thermal standards are maintained during transportation. Whether it’s vaccines that need to remain within a defined temperature range to ensure safety and efficacy, heat-sensitive chemicals and adhesives that can be damaged by inappropriate storage, or last-mile monitoring to ensure food-safe delivery of hot or frozen foods, a custom NFC solution can ensure that products stay within safe conditions throughout their journey.
4. Predictive maintenance
From factory floors to remote field assets, custom NFC monitors the temperature, vibration, or humidity of critical equipment – without wires, batteries, or expensive infrastructure.
Just a tap of a smartphone or reader gives access to real-time data to help predict failures before they happen, reducing maintenance costs, cutting unplanned downtime and extending equipment lifespan – while making every maintenance check fast, accurate, and data-driven.
5. Health monitoring
Whether it’s tracking hydration, temperature, heart rate or skin pH, NFC-sensor integration brings quality insights straight to the point of care, enabling real-time health monitoring that’s seamless, non-invasive, and battery-free.
One tap of a smartphone or reader gives instant access to biometric data – prefect for remote care, chronic condition management, or next-generation wellness devices. Importantly, ultra-thin, flexible FlexICs remove the need for bulky, expensive equipment enabling lightweight, low-cost smart devices that are discreet and comfortable to wear.
