In today’s complex supply chains, simply knowing the location of goods is only the initial step. To truly ensure product quality and safety, achieving full traceability and understanding the environmental conditions assets have been exposed to throughout their journey is necessary.
The main goal of a track and trace solution is to provide essential information regarding goods and services, including how they were produced, the materials used, the certifications applied, their arrival in the country and at the store, and their quantity. Now, imagine being able to access environmental data throughout this entire product journey…
This is the Track Sense Trace solution, the optimal way to guarantee customer satisfaction and prove the origin and management of your goods and services. It’s the best approach to offer a superior product, one where you control the quality and the customer can trust because of your investment in time, effort, and technology to bring it to them.
Track and trace solutions have already proven their benefits and ROI in many industries. Now, the ability to add environmental condition data like temperature and humidity offers numerous opportunities. This sensor data plays a critical role in maintaining the integrity of many products, from perishable foods and pharmaceuticals to sensitive materials.
Understanding the geographical and environmental context makes customers very aware of the origin and how the product has been managed. Sharing this data with customers could be a real added value and a significant commercial advantage.
Sensory RFID: a transformative solution
Maintaining product integrity requires accurate temperature and humidity monitoring. However, traditional methods like manual checks are inconvenient and prone to error, while battery-powered IoT solutions can be costly due to battery replacements and additional hardware. Battery-less sensory RFID offers a compelling alternative, enabling precise, real-time, and cost-effective environmental tracking. Leveraging your existing UHF RFID infrastructure for supply chain management allows you to integrate this sensor data into your warehouse management system and supply chain software, with no additional cost.
This technology represents the next evolution beyond traditional track and trace, building upon the established benefits of RFID in logistics and supply chain monitoring. Introducing Track Sense Trace: a new approach that empowers you to develop your business by reducing waste, optimizing processes, and enhancing the efficiency and productivity of your solutions.
Furthermore, this enables you to enhance your brand image and provide a clear quality differentiator to your customers by demonstrating proactive environmental monitoring.
How does it work?
Items to monitor are tagged with RFID labels which provide real-time temperature, humidity and unique identification for each item.
Tags are read by RFID Readers and antennas installed at critical checkpoints, such as loading docks, warehouses, and receiving areas.
Finally, a centralized data management system, either cloud-based or
on-premise, provides a secure repository for storing environmental data.
Main fields of application

Food Freshness
Ensure traceability and compliance, guarantee freshness, and reduce waste with proactive cold chain temperature monitoring.

Pharmaceutical
Safeguard drug safety and ensure proper distribution by tracing and monitoring conditions in primary packaging, prefilled syringes, or batches throughout the entire supply chain.

Sensitive materials
Prevent degradation and mold formation during transportation and storage of sensitive materials like wood and paper keeping trace of temperature and humidity.
At the heart of the solution: the AS321X chip
The AS321X chip family from Asygn is a game-changer in this field. This battery-free, EPC Gen2 compliant RFID chip is designed specifically for sensing applications, with a key focus on temperature, relative humidity, light or deformation.

Up to 7 meters reading range
including sensor supply

Internal / External Sensors
Temperature, Relative Humidity,
Ambient Light, Strain…

Battery free
Integration made simple

Since the AS231x family is ISO and GS1 compliant, RFID sensory chips behave just like standard RFID. Any reader or existing infrastructure can be used to retrieve identification and sensory data.
Integration with EPCIS compatible software or ERP systems is straightforward. This allows you to comply to regulations such as FSMA 204 or Digital Product Passport (DPP) with no efforts.
Take a look at our web demo dashboard: some tags are deployed and read by a standard RFID reader. Results are sent to the cloud and available live 24/7.
Not only temperature or humidity...
The AS321X chip family exists in multiple versions: all feature temperature tracking by default, then relative humidity, strain and light can be chosen as additional embedded sensor.
Want to connect your sensor? Capacitive or resistive, this is possible: accelerometer, pressure, moisture or pick-to-light, it is up to you.
