Abstract
An RFID tag formed on an original includes a storage unit which stores data representing, e.g., the number of times of scan of the original and the generation from a parent original, and a transmitter/receiver which transmits and receives the data by radio. A read/write circuit receives data from an RFID tag of an original by radio. On the basis of the received data, read of the original is controlled. While the original is being read, the received data is edited in accordance with the control. The read/write circuit transmits and writes the edited data in the RFID tag.
