Smart Sensing Solutions for a data-driven world

We’re entering a new era of traceability—one where transparency and compliance aren’t just expectations, but essentials. Environmental, structural, and material data can now be captured wirelessly, at scale, and in real time — with the simplicity and affordability of a smart label.

At 4id, we’re embarking on projects that utilise sensor-enabled RFID labels and tags to support ground-breaking applications — from temperature and humidity monitoring in cold chain logistics, to strain sensors for predictive maintenance, and volumetric sensing of packaging for the healthcare and hospitality industry.

These labels are enabling next-gen use cases across medical technology, pharmaceuticals, hospitals, fast-moving consumer goods, logistics, and industrial operations.

Passive, Powerful, and Scalable

Unlike bulky hard sensor tags, our products are passive — meaning they contain no battery, and only require a short pulse of energy from a reader to return their unique ID and sensor data.

This makes them:

  • Cheaper than any active or hard tag alternative

  • Easy to apply to high-volume items or surfaces

  • Scalable for applications once considered cost-prohibitive

Sensor-enabled smart labels can now do what only hard tags once could — with more flexibility and far less cost.

Data Beyond Identification

These tags go beyond basic traceability — they support transparency, regulatory compliance, and environmental accountability. In industries where proof matters, they deliver intelligence.

We’re actively working with partners to bring a new wave of sensing capabilities into passive formats, including:

And we’re just getting started.

Temperature

Strain

Humidity

Volume

“What if every product told its temperature journey?”

“What if you could pinpoint the moment concrete foundations were set?”

“What if your packaging could detect humidity and alert you before damage occurs?”

“What if you could tell exactly how much liquid is in every bottle of spirits in your bar?”

What are your ‘what if‘ questions when it comes to RFID sensing in your business?

From warehouses to worksites.

From stores to supply chains.

What data will help you become more compliant, save time & money, or prevent wastage?

These projects are big — and so are the ideas behind them

We’re already manufacturing sensor labels for high-impact projects. One example is measuring strain in Black Hawk helicopter blades for use in predictive maintenance. Another is enabling supermarket chains to monitor the temperature range of fresh food in transit and storage to ensure compliance and food safety. These solutions are just the beginning of what’s possible.

If you have a big idea and need a partner who can keep up, we’re ready to help you build what hasn’t been done before.
