LF RFID Tag

Low Frequency RFID tags normally operate at 125KHz and 134KHz, its data is transmitted via inductive coupling electromagnetic, which means that the RFID reader induces a current in the RFID tag which then powers the RFID tag and sends out some basic identification information to the RFID reader. LF tags are usually passive and do not require a power source or battery.

Low Frequency tags can be made to different form factor for different applications, typical form factor is card, glass tube, coil, plastic brick and disc. LF RFID card tag is mainly used for access control, LF glass tube tag is always implanted into animal body for animal identification or embedded into assets for automation and work in process management. LF coil tag is used to make RFID ear tag for farm animal management. for LF brick tag, it is special designed for immobilize management, used for car manufacturing and after sales market. LF disc tag is widely used in industrial application like inspection management, work in process management.
