Summary
LEFX Unit System is RFID (Radio Frequency Identification) device for an
Inductive loop coupling. This system has two modules of the Reader/Writer
(LEFX-C) and Tag (LEFX-T).
-
LEFX generates a 125kHz signal on an internal looped antenna.
-
Transmitted data are modulated using Amplitude Shift Keying (FSK)
modulation.
modulation.
-
Received data are demodulated from the Tag load variation signal,
generated on the antenna.
generated on the antenna.
-
Tag is battery less memory with a looped antenna.
