The active UHF tag has the ability to transmit temperature data in real time, making it ideal for tracking refrigerated items throughout a supply chain, according to GAO. The tag can also trigger an alarm it the tagged item’s temperature exceeds preset limits.
The tag operates at a frequency of 2.45 GHz and can withstand temperatures ranging from –58 F to 302 F. The tag also features a read range of up to 100 meters and a battery life of four years, as well as an anti-collision solution that allows 100 tags to be read simultaneously without interference.
