摘要： There is provided a tag IC that radio waves transmitted from the tag IC is intensified, so that information stored in the tag IC can be read even if the distance between the tag IC and a reader is increased. The tag IC comprises an antenna that receives/transmits signals from/to the reader with AC electromagnetic energy, an IC chip that decodes received data from the reader, calculates transmitting data based on stored data, and transmits data, and a solar cell that directly converts optical energy to electrical energy to supply power to the IC chip.
