Abstract
A method for identifying an RFID (Radio Frequency IDentification) reader is provided. A first transmission path is defined between a first RFID reader and a host apparatus in a RFID system. A second transmission path is defined between the host apparatus and a second RFID reader adjacent to the first RFID reader. When the host apparatus is identifying the first RFID reader, the first RFID reader sends first identification data of the first RFID reader through the first transmission path to the host apparatus. The first RFID reader also sends first-resent identification data of the first RFID reader through the second transmission path to the host apparatus. The host apparatus identifies the first RFID reader by comparing the first identification data and the first-resent identification data transmitted through the first transmission path and the second transmission path respectively, thereby double confirming the identification data of the first RFID reader.
