    摘要: A system establishes synchronicity of transmission and receiving for each reader/writer of an RF tag independently without obtaining synchronization of the reader/writers by means of an unspecified number of control terminals is desired as a reader/writer system. A reader/writer comprises a transmitter operable to transmit an interrogation signal to an RF tag, and a receiver operable to receive a response signal from an RF tag, wherein the transmitter is operable to transmit an interrogation signal based on a synchronization signal received from another reader/writer.
