RFID technology continues to play a bigger role in the food and cold chain, where spoiled product represents a huge problem. It is estimated that 40 percent of the food in the U.S. goes uneaten. Reducing food losses by just 15 percent would be enough to feed 25 million more Americans, according to the Natural Resources Defense Council.
That’s where RFID comes into play. A new battery assisted passive (BAP) UHF RFID tag from Confidex is designed specifically for cold storage and cold chain applications.
The label monitors storage and transportation temperature of perishable goods such as fresh food, pharmaceuticals or sensitive chemicals. If predefined upper limit or lower limit is violated during the monitoring period, an alarm is issued and stored into the memory of the label. This allows users to detect the interruption point in a cold chain with any commercial UHF RFID reader, anytime during transportation and storage.
The user sets the desired temperature limits, measurement interval and other configuration data prior to attaching the label to the monitored item. When preferred, the configuration data can already be set at the Confidex factory. The Confidex TempLabel™ is disposable.
