Savi® Active RFID Tags

Savi RFID Tags consist of a family of ruggedized, battery-powered RFID devices built to support dependable and sustainable RFID solutions. Savi RFID Tags enable organizations to access real-time information on the location of assets and shipments, as well as their condition and security status. Savi RFID Tags have been battle tested globally for two decades, and they are what organizations around the world rely on to ensure their mission critical supplies reach their destination. Today, Savi RFID Tags track hundreds of thousands of shipments per year in more than 50 countries across the global supply chain.

Savi RFID Tags support active RFID interoperability on a worldwide basis through compliance with the international active RFID ISO 18000-7 standard. All Savi RFID Tags are HERO and RoHS certified.

Savi RFID Tags for Assets and Consignments

Savi RFID Tags are built to drive effective and accurate real-time tracking of assets and shipments throughout the global supply chain. Savi's flagship active RFID tag is the ST-654, which features a large database memory (128 Kbytes), 400 feet (122 m) of omni-directional RFID communications range, rugged design, replaceable battery and a variety of mounting options. Savi's other RFID tags offer selective features, different levels of database memory and are available in various form factors.

  • Savi Tag ST-602: The ST-602 asset tag is Savi's smallest active RFID tag which has a ruggedized form factor and is easy to mount on various assets, including pallets, manufacturing parts and IT equipment. The ST-602 is ideal for tracking containers and their contents within facilities or across geographies.
  • Savi Tag ST-616: The ST-616 was designed to be mounted on a smaller class of assets than other RFID tags, including pallets, containers and rolling stock. The ST-616 offers flexible mounting options and features a unique, low-profile form factor that makes the tag less prone to damage.
  • Savi Tag ST-618: The ST-618 was designed for tracking assets and carries enough memory to record asset configuration and maintenance records. The ST-618 is ideal for locating, tracking and managing medium- to high-value assets.
  • Savi Tag ST-621: The ST-621 license plate tag is designed for quick commissioning and is ideal for tracking shipping containers, rolling stock and other conveyances.
  • Savi Tag ST-654: The ST-654 is a high-performance, data-rich asset tag suited for various applications, including the tracking of shipment containers, vehicles and other large assets. The ST-654 can hold a variety of data, from simple IDs linked to a server database, to detailed shipment manifests.
  • Savi Sensor Tag ST-656-I: This tag consists of a high-performance, active RFID device that aids in tracking an ISO container during transportation through the global supply chain. The ST-656-I is a new approach to container door tags, enhancing the security offerings — it is a door-mounted device that differs from an asset tag in its placement on cargo shipping containers. The ST-656-I is placed on the left door of an ISO compliant container and held in place by its own spring clamp design.

Savi Sensor Tags

Savi Sensor Tags are ideal for real-time tracking and environmental monitoring of sensitive, perishable items such as medical supplies, ammunition and food. Savi Sensor Tags feature sensors that monitor and record environmental status data to an event log in the tag's memory. If the collected data rises above or falls below the user-configured range, the tag sends a real-time alarm to an RFID reader, and the alarm is escalated via cell phone or email notification, allowing personnel to either address the situation or enact contingency plans for replacing the damaged goods.

All Savi Sensor Tags feature temperature and humidity sensors. The Savi Sensor Tag ST-675 is also equipped with shock, intrusion and light sensors.

  • Savi Tag ST-673: This tag features sensors that monitor and log the temperature and humidity of assets and their contents. The ST-673 is packaged with a metal mounting bracket that allows the tag to be easily fastened to engine containers, vehicles and other metallic assets. With its externally mounted low-profile encasement, the ST-673 is ideal for harsh outdoor environments.
  • Savi Sensor Tag ST-674: This tag features sensors that monitor and log the temperature and humidity of assets and their contents. The ST-674 is packaged with a mounting sleeve that allows the tag to be fastened inside plastic, polycarbon, cardboard or wooden totes and containers, or to pallets or racks during transport, or on warehouse shelves and other fixtures during storage.
  • Savi Sensor Tag ST-675: This container security tag comes equipped with temperature, humidity, shock, intrusion and light sensors. The intrusion and light sensors detect potential theft or tampering. The ST-675's unique C-clamp door-mount design places the sensitive RFID components inside the shipping container. Only the low-profile, external antenna casing is on the outside of the container, which significantly reduces the risk of tag damage.

Savi GlobalTag™

Savi GlobalTag (ST-694)

Click To Enlarge

The Savi GlobalTag (ST-694) is a data-rich active RFID tag equipped with a Satellite Modem and a GPS Receiver. This tag is suited for tracking high value assets throughout the supply chain. The GlobalTag is capable of tracking an asset with or without active RFID infrastructure.

The GlobalTag includes a Satellite Modem for communications anywhere RFID readers are not available. When RFID infrastructure is not present, the GlobalTag automatically uploads data to RFID networks via satellite. GlobalTag provides GPS location coordinates with every satellite transmission. Unlike other satellite tags, GlobalTag has active RFID functionality, so battery power is not expended on satellite communications when the tag is within range of an active reader.
