METHOD FOR DETECTING RFID TAG USING RFID TAG DETECTOR

摘要

The present invention relates to a method for detecting an RFID tag laid underground by using an RFID tag detector, wherein the RFID tag detector wakes up an RFID tag laid underground by setting the strength of transmitting radio wave to be maximum. The present invention can detect the laying depth of the RFID tag by transmitting the radio wave while changing the strength thereof.
