摘要： A communication system comprises an IC tag, and a reader/writer for performing radio communication with the IC tag. The reader/writer further comprises an encoding unit for encoding a digital signal having at least one bit and generating an encoded signal and a transmission unit for transmitting a modulated wave acquired by modulating a carrier based on the encoded signal during an acceptance period when the encoded signal is accepted in the IC tag, and transmitting the carrier to the IC tag during an execution period when the processing based on the encoded signal is executed in the IC tag. The IC tag further comprises a receive unit for receiving the modulated wave or the carrier transmitted from the reader/writer and a power supply voltage generation unit for generating the power supply voltage based on the received modulated wave or the carrier.
