Abstract
An RFID device is capable of stopping and restarting a response via a response stop command. The device is capable of initializing a part of or the whole of internal data including a response restart set data storage portion. The device is capable of using command data from an external communication equipment to look up response restart data at the restart of a response, deciding a data storage area and content that may be initialized when the restart is possible, and rewriting a data storage portion.
