ABSTRACT:
A contactless ID chip to which a signal is inputted from an antenna by a wireless means, where data can be written only once. In the contactless ID chip having a nonvolatile EEPROM, data indicating whether writing is performed to the EEPROM is written simultaneously with basic data writing, and once writing is performed to the EEPROM, other data cannot be written thereto.
