摘要： A radio frequency identification (RFID) communication system and method is provided to resolve the power-consuming problems of an active RFID tag while operating at a receiving mode in a long duration. A designated channel is established between the reader and the RFID tag, and also the reader sends a designated message so that the actuated active RFID tag can receive the designated messages and dynamically enter into a receiving mode. Therefore, normal communications may be conducted between the reader and the RFID and the usage period or technical performance can be improved as well.

摘要： A radio frequency identification (RFID) system employs multiple band transmission to prevent signal collision. The system includes a plurality of RFID tag groups and at least one RFID reader. Each RFID tag group includes at least one RFID tag. The RFID tags of the same RFID tag group are operated for radio frequency transmission in the same transmission frequency band, and those of different RFID tag groups are operated for radio frequency transmission in different transmission frequency bands. When the RFID reader simultaneously receives radio frequency signals issued from RFID tags of different RFID tag groups, since they are transmitted in different transmission frequency bands, signal collision among the RFID tags of the RFID tag groups can be avoided.

摘要： 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.

The RFID system includes one or more RFID reading device to receive respective tag information from a plurality of RFID tags. Multiple RFID tags of the RFID system each includes a microprocessor connected to a random code generation unit, a power supply unit, a memory unit and a radio frequency transceiver module. The memory unit stores the respective tag information that contains a tag identification code. The microprocessor of the RFID tag issues a base number or uses the tag identification code to generate a random code and a tag signal is transmitted to the RFID reading device in accordance with the random code so generated.
