Verification of temperature conditions

Cold chain traceability at the pallet level

“We are happy to introduce the WIT Tag, into our family of IoT solutions that integrates GPS, RFID, Sensors with low energy wireless technologies to expand the capabilities of asset tracking” says Ramses Maldonado, EVP of Wireless & IP Technologies (WIT). “This technology will provide producers, importers-exporters and distributors with a complete cold chain visibility solution (from the farm to the pallet).” The key is to help prevent problems and verify that products were handled under proper temperature conditions. The Tag works for any temperature sensitive commodity, which includes fresh as well as processed produce, e.g. fresh-cut bagged salad or frozen produce.



Placed inside a container or the truck cargo area
The WIT Tag communicates temperature, humidity and geo location in almost real time into WIT's 3G water proof GPS tracker which then re-transmits the data to the company's cloud based software. The tag starts working from the time it was loaded into the cargo area when it arrives in the destination. Additionally, the Tag senses changes in light so it can also generate a record and alerts each time the door were open. The platform can send email and text messaging alerts on preferred thresholds. The Tag is completely re-usable and battery life can be up to 10 years.

“WIT Tag is an economical solution to help audit the supply chain and keep records of the integrity of the product” added Maldonado. “It supports companies transporting temperature sensitive cargo by providing a centralized data collection of both cargo temperature across the journey while matching it with geo location based intelligence.” 


1. WIT Tag is placed inside a box or cargo area. It collects temperature and humidity data
2. Tag sends information to GPS gateway, connected to the truck or container
3. Data sent to Cloud Based Software (access via web browser anywhere)
4. Cargo tracking & monitoring solution
