Active RFID Tags: Sense Respond ...

Savi introduces active RFID tags that sense and respond to environmental conditions in the global supply chain. ...

... "In addition to RFID components that automatically locate goods in the supply chain, the ST-673 and ST-674 contain sensors that monitor temperature and humidity changes of the container's contents or other supply chain assets. When commissioning the tags, users can set acceptable temperature and humidity ranges tailored to the characteristics of the particular goods to be monitored. The Savi ST-673 and ST-674 are active RFID tags that provide visibility to assets and shipments as they move through the supply chain. In addition, the tags periodically record the environmental status data to an event log in the Savi SensorTag's memory. If the collected data rises or falls outside the acceptable condition range, the Savi SensorTag sends a real-time alarm to a fixed or mobile RF reader, and notification of the temperature or humidity change is escalated via a web application, cell phone or email, allowing the problem to be addressed immediately before spoilage or damage occurs. The complete environmental event logs can be uploaded to handheld readers or to fixed readers at stationary sites such as yards and warehouses in the supply chain. This enables users to identify the time and location of unacceptable environmental conditions, or to confirm that acceptable ranges, and therefore shipment quality, are maintained throughout the journey.

The ST-673 and ST-674 sensor tags are each about 6x2 inches, have memory storage of up to 128K bytes of data and are highly ruggedized for harsh environments. Savi Technology's active RFID tags, which have been deployed to track over two million shipments in over 2,000 supply chain locations for defense and commercial customers, include read ranges of up to 300 feet, beepers for audio location and rugged designs that can withstand the most harsh climatic conditions. Savi's family of active RFID tags are based on Savi's EchoPoint Technology, an innovative technology that combines Ultra High Frequency (433.92 MHz) and Low Frequency (123 kHz) communications for both long-range and more precise spot-level location. This technology also enables data to be written to the tags while they're in-transit, as well as to capture important data about the shipment from mobile readers. " ...
