Enhance tracking and monitoring of the products during
The company provides logistics and cargo monitoring,
management, and information solutions serving the worldwide
perishable product supply chain. The company develops
solutions to monitor the condition and location of the
cargo during the transportation of various perishable
products (Food and L&S).
The client approached us to develop an IoT prototype to
allow tracking and collection of information about the
cargo at the case level through NFC and UHF enabled smart
labels. The solution would potentially solve a problem of
tracking at the case level at low cost, touchless transfer
of the data into the cloud for decision making, proof of
delivery, and integrity of the products.
Ensure robust communication between tags and
The main challenge was to ensure a stable connection and
smooth integration between tags and software since we had
two types of tags — NFC and UHF — that required different
software and firmware. Also, we needed to understand how to
read data from tags and set up configuration without proper
Mobile apps for sending notifications to users, as well as monitoring and reading NFC tags

data to a readable device

System for temperature monitoring and crime risk
We needed to work with the Azure IoT Hub to connect,
collect, and process telemetry from the devices. This
included gathering information from NFC and UHF tags that
provided location and temperature information.
The first project was to create an IoT solution designed for temperature monitoring and GPS tracking of
various products. For example,
when transporting medicine, vegetables, or fruit, the product can deteriorate if the temperature goes beyond acceptable limits.
To prevent this from happening, each of the containers had
an NFC or UHF/NFC tag. These tags can collect the current
temperature of the product and be read by using mobile
phones in the case of NFC or by UHF readers to collect the
data and transfer to the cloud.
The temperature and scanned GPS location is sent to the
Azure cloud and analyzed in real-time through the mobile
app or web-portal. This way we can continuously see how the
cargo had been moving and how the temperature was changing,
and in case of unwanted heating or cooling the
administrators and drivers were notified with a warning
The project includes:
A web portal for admins based on ReactJS to capture
info from the tags and map movement and temperature
variations in real-time
An IoT system for monitoring and analysis based on the
Azure IoT Hub. As for communication between devices, we
used HTTPS, WSS, AMQP, and MQTT protocols to support
Mobile apps, both native iOS and Android, for sending
notifications to users, and monitoring and reading NFC

As a result, the client received a
fully-equipped IoT system for iOS and
Android and desktop applications for
monitoring and analysis of NFC/UHF tags.
The system provides real-time location,
status data, and critical activity alerts
to enable proactive management of every
