Savi Technology has introduced a new low-profile version of its active, RFID tag for military and commercial container shipments in severe, supply-chain operating environments. Called the Savi Tag ST-656, the ISO container door tag comes in a new U-shaped form factor that clamps tightly onto the left door of the container, enabling the RFID electronics to be protected on the inside of the container while a low-profile plate on the outside contains an antenna that communicates with fixed or mobile reader networks. The flat external plate also contains a beeper for audio alerts of the tag's location and status.
The combination of a low-external profile and the protected RFID components reduces the risk of damage to tags in harsh operating environments while retaining the same performance and features of the Savi Tag ST-654, which has become the standard, active tag providing real-time visibility of military supplies for the Department of Defense and other allied defense organizations.
The ST-656 includes an onboard processor, memory and radio transmit and receive capability. These RFID components are protected on the inside of the container, enabling users to recover critical manifest data--even if the outside is damaged.
The active tags are based on ISO 18000-7 standards operating at 433.92 MHz, which has proven to be the most effective RFID frequency for bending around metal objects such as large ISO containers that are tracked and stored.
Savi’s family of active RFID tags are based on Savi's EchoPoint technology that combines UHF (433.92 MHz) and LF (123 kHz) for long-range and more precise spot-level location. This technology also enables data to be written on a tag while it is in transit, as well as to capture important data about the shipment from mobile readers.
