RFID Geeks

Unlike with other materials, RF waves cannot penetrate metal. Metal blocks and reflects RF waves, which poses quite a challenge when using RFID technology for tracking metal assets or in environments with a lot of metal objects. And that’s not all, metal also couples with the tag antenna and detunes the tag so the read range is drastically shortened. This means that a common passive RFID tag placed on a metal asset cannot be read from a distance even within the line of sight or performs ve …
