RFID Journal claims to be the world's largest, most trusted authority covering RFID and its many business and consumer applications, where editors provide insightful coverage often not to be found anywhere else. The article describes why Höganäs AB, a Swedish maker of metal powders, switched from RFID to Swedish passive infrared identification system, dubbed IRID for infrared identification. It had been using an RFID system to identify containers, but it faced several problems with RFID. For instance, Höganäs was using a system with a low read range because that was what was available at the time of installation many years ago. Occasionally vehicles were run into readers, and replacing the parts was difficult. In addition, the metal environment of the factory caused RF interference—that is, it was hard to set the tags at the right distance from readers. When Höganäs decided to replace its older RFID system, it considered an RFID platform with a longer read range, as well as bar code technology. It decided against longer-range RFID system because of the risk that an interrogator would capture data from the wrong tag and that multiple interrogators might interfere with one another. Moreover, the price of the RFID system was high in comparison to the IRID system. Höganäs dropped the idea of a bar code system because it feared that airborne metal dust in the factory would quickly coat the bar code labels, making them illegible. Höganäs' own tests before ordering the system from Scirocco showed that IRID signals, with have a wavelength twice as long as that of visible light, penetrate the metal dust on tags and interrogators without significantly reducing the read range.
