Abstract
Provided is a reader for radio frequency identification (RFID) and a RFID system. A reader for RFID that receives a channel signal comprises a frequency oscillator generating an oscillating signal at a frequency that is offset by an offset frequency from a center frequency of the channel signal, a mixer mixing the channel signal with the oscillating signal that is offset, and a filter filtering a mixed frequency signal provided from the mixer. The reader for RFID and the RFID system are improved in reception for the wave identification using a listen before talk (LBT) mode for identifying an electronic tag.
