Rfid Tag Magnetic Field

Magnetic field cross section square readerantenna inductive. An rfid tag in its most simplistic form is comprised of two parts an antenna for transmitting and receiving signals and an rfid chip or integrated circuit ic which stores the tag s id and other information.

24 inductive rfid magnetic flux in rfid systems chapter 4 protection at uhf or microwave frequencies. Originally rfid tags were used to track large items like cows railroad cars and airline luggage that were shipped over long distances. The little bit of research i ve done hasn t been able to uncover any issues of interference to rfid by magnetic fields except for one paper which studied the effects of magnets in the digestive track of cattle on rfid ear tags and found that some interference did occur in some cases. A static magnetic field caused by a normal magnet should not cause any harm to a rfid tag.

These original tags called inductively coupled rfid tags were complex systems of metal coils antennae and glass.
