Identiv’s uTrust Sense Temperature Tracker is a credit card-sized powered smart sensor that tracks and stores temperature readings and can be read locally by radio frequency identification (RFID) readers, such as mobile phones, or uploaded to the Internet for analytic purposes. The uTrust Sense Temperature Tracker contains a precise temperature sensor, digital storage, a flexible battery, and supports near field communication (NFC). The tracker can communicate with a variety of local devices using an application on consumer mobile devices or industrial equipment to read the complete logged history recorded on the tracker.

Even after battery life has drained, the tracker can still be used as a passive temperature sensor label, providing the present ambient temperature. The entire memory content, including the measurement values, are still fully accessible, eliminating the risk of data loss and enabling further applications even after the data-logging capability has stopped.
