Researchers at Pacific Northwest National Laboratory (PNNL) have developed miniature radio frequency (RF) tags that are ideal for rapid, remote inventory tracking and monitoring a wide variety of items. The PNNL technology provides long-range readings, simultaneous readings, the ability to monitor inputs and control outputs, and location tracking. RF tag systems offer an advantage over bar-coding inventory and monitoring systems because line-of-sight access to the tagged items is not necessary. The PNNL RF tags exhibit superior performance in difficult environments such as reading through container walls, paint, dirt, and in cluttered areas.
With more than ten years of experience and a broad range of expertise, PNNL's Electronic Systems Group offers three types of RF tags in its suite of available technologies: active, semi-passive, and passive. In addition to offering general features and benefits for different applications, PNNL can customize its tag systems to meet specific needs.
