ABSTRACT:
A communication system includes a wireless IC tag and a reader/writer that performs reading and writing on the wireless IC tag via wireless communication. The reader/writer includes an error control encoder and an error control decoder. On writing data into the wireless IC tag, the reader/writer encodes the data by the error control encoder and writes real data separately from error-control-decodable data. On reading out data from the wireless IC tag, the reader/writer selects whether to read out only the real data or to read out data including error-control-decodable information to decode the data by the error control decoder based on error control information indicating whether to perform error control or not.
