Las Vegas — May 4, 2006 — Radio frequency identification solution provider Savi Technology has released two sensor tags intended to reduce spoilage and damage by monitoring the temperature and humidity of military and commercial shipments, including aircraft engines, ammunition, medical supplies, food stuffs and other perishables vulnerable to environmental conditions as they move through the supply chain.

The Savi SensorTag ST-673 and ST-674 were introduced here during the RFID Live! conference in Las Vegas this week.

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 two units are active RFID tags designed to 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 rise or fall 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 e-mail, increasing the likelihood that the problem will be addressed 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.

"By alerting users to problematic environmental conditions when goods are moving through the supply chain, these new active RFID products reduce losses due to spoilage or damage," said David Kranzler, Savi's senior vice president of product development.

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 ruggedized for harsh environments. The two newest additions to Savi's family of active RFID sensor tags provide new form factors and mounting options to accommodate a range of metal and non-metal containers, according to Savi.
