A system for improving a tag recognition rate is provided to prevent generation of mutual radiowave interference although multiple RFID(Radio Frequency Identification) transceivers including readers and tags are disposed to maintain stable RFID communication. A signal coupling unit(140) couples RF signals received from a tag(300) or a reader(200). A voltage regulating unit(170) regulates the voltage of the coupled signal to have a certain level. A signal converting unit(150) synthesizes the RF signals transferred from an antenna into an IF(Intermediate Frequency) signal by using the voltage-regulated signal as an oscillation frequency signal. A signal processing unit(160) processes the IF signal to generate tag information. A data transmitting/receiving unit(180) transmits the tag information through a wired/wireless network.
