RFID tags can resist metal interference

by:JLTcard     2020-11-18
RFID is a radio frequency identification tag, the use of radio waves for data transmission, is a non-contact automatic identification technology. Now, it has been widely used in manufacturing, logistics, identification, retail, health care, anti-counterfeiting security and other fields. Although RFID technology application range is very wide, and is not very tall to the requirement of the environment, but RFID radio waves susceptible to metal interference, and will affect the normal reading of the tags in the radio, will even miss the label. To read. So is there any way to solve the metal interference with RFID tags? At present, the most commonly used method is in RFID tag paste on the back of a layer of magnetic materials. Absorbing material permeability is generally higher than the permeability of metal materials, so they can change the magnetic field environment RFID tags. The tag and reader is adjusted for the same frequency can make the RFID tags to perform normal read operations. The label is the so-called metal RFID tags.
