How it works

A Simple Way to Monitor and Confirm Cold Chain Integrity.

Step 1
Scan and Apply the Sensor

Scan the WarmMark QR code to log the serial number and apply the sensor to the package. This links the sensor to the shipment and prepares it to monitor temperature.

Step 2
Sensing Shipment Temperature

During transit, WarmMark QR monitors the surrounding temperature. If it exceeds the predefined threshold, the sensor window irreversibly changes from white to red/pink.

Step 3
Scan Upon Delivery

At delivery, the recipient scans the QR code using their smartphone. A guided process captures the sensor’s color and returns clear condition information based on exposure.

Step 4
View Records in the Cloud
The time, location, serial number, and sensor status recorded from every scan can be viewed in the SpotSee Cloud to ensure traceability and compliance throughout shipping.

Need to Detect Exposure to Cold or Freezing? Use ColdMark®.

 

While WarmMark QR alerts you to heat exposure, some products are just as vulnerable to cold or freezing conditions. That’s where SpotSee ColdMark comes in.
