Our technology offers many advantages. It permits 'no line of sight' reading. The tags can can be embedded in most materials. It is low cost. Tags can be read through water, snow, concrete, bricks, plastics, wood, and most non-metallic materials.
Tags are extremely difficult to duplicate offering a high degree of security.
However because it uses magnetic field coupling it has a small maximum read range. The following chart shows actual read distances of our different stock RF ID tags, readers and some custom designs. These were measured in open air without interference. Depending on your environment, your results may vary. . This capability allows the reader to detect and read many tags placed at the same time in its read field.
