摘要:
In a communication system including a RFID tag, which has a function to record information and a function to carry out wireless communication with an external device and is capable of transmission with using both FM modulation and AM modulation, and a reader/writer for writing and reading information onto and from the RFID tag via wireless communication, a transmission to transmit information from the RFID tag to the reader/writer is carried out with using one of the FM modulation and the AM modulation at the RFID tag. If the reader/writer fails to decode a signal transmitted with using the one of the FM modulation and the AM modulation, transmission with respect to the information is carried out with using the other of the FM modulation and the AM modulation at the RFID tag. In this manner, reading error of data sent from the RFID tag is prevented.
