METHOD FOR READING TAG IN MOBILE RFID ENVIRONMENT

摘要

A method for recognizing a tag in a mobile RFID(Radio Frequency IDentification) environment is provided to enable plural RFID readers to use retransmission when attempting access to a medium for the recognition of a single tag, thereby effectively solving a conflict problem and identifying the tag with a high recognition rate. A method for recognizing a tag in a mobile RFID environment comprises the following steps of: transmitting a tag identification request signal to a tag to recognize(S3); waiting the reception of a response signal from the tag(S4); and retransmitting the tag identification request signal after a predetermined delay time passes when the response signal is not received.
