RF Controls has a passive RFID tag solution that provides precise location tracking of tagged items over long distances that also works without batteries.

Over the last several years, tracking and tracing the movement of goods across supply chains has been dominated by radio frequency identification (RFID) tags that help stakeholders identify product locations in real-time. These conventional RFIDs are usually involved with minimal fixed infrastructure – like portals, tunnels around conveyor belts, or on handheld solutions used by employees to scan areas of interest within warehouses.

RF Controls, an asset-tracking solutions provider, has developed a real-time location system of passive RFID tags that can work without a battery, thereby exponentially improving the usability of the tags. “Our battery-free tags have the ability to scan an area with high speed, over long distances and with high accuracy. The particular protocol we use is called the RAIN RFID,” said Adrian Turchet, senior vice president of strategy at RF Controls.

Unlike traditional RFIDs, RF Controls provides a complete overhead solution, illuminating a room with radio frequency waves that allow people to identify a tag with one-foot location accuracy from anywhere inside the building. Turchet explained that a “big component” of RF Controls’ real-time locating system (RTLS) is built around the concept of last known location.
