PURPOSE: An RFID(Radio Frequency IDentification) tag control method is provided to use information or data inputted through a sensor, thereby overcoming the limit of storage capacity in a tag. CONSTITUTION: Digital data obtains an analog signal which is sensed through a sensor(430). Whether or not the data relates to the operation of a terminal is confirmed by reading the data(440). When the data relates to the operation of the terminal, the data is provided to the terminal in response to a wireless frequency signal which is received through an antenna(450). When the data does not relate to the operation of the terminal, the structure of the data is matched to and stored in the storage structure of a storage area(470). [Reference numerals] (400) Activate an RFID tag; (405) Sensor of the RFID tag monitors external input data or information; (410,445) No; (415,460) Yes; (420) Sensor of the RFID tag senses the external input data(or information); (425) Sensor delivers the sensed external input data(or information) to a conversion unit in the tag; (430) Conversion unit converts the external input data(or information) into a predetermined type or structure to be stored in the tag; (435) Conversion unit delivers the converted external input data(or information) to a determination unit; (440) Determination unit determines whether or not the delivered external input data(or information) can be stored in a memory of the tag; (450) Determination unit requests deletion by transmitting the external input data(or information) to a control unit; (455) Control unit deletes the external input data(or information); (465) Determination unit transmits the converted external input data(or information) to the control unit; (470) Control unit stores the converted external input data(or information) in the memory; (475) Request the external input data(or information) stored in the memory from a predetermined terminal or device; (480) Control unit delivers the requested external input data(or information) to a transmission unit by extracting it in the memory; (485) Transmission unit transmits the extracted external input data(or information) to the terminal or device; (AA) Start; (BB) External input data(or information) exists?; (CC) Storable; (DD) End |
