PURPOSE: An RFID tag with a data restoration function is provided to enable an RFID tag with a data restoration function to store flag data during data retaining time when a power voltage is not temporarily or continuously supplied to an RFID tag, thereby restoring the flag data by supplying a power voltage again. CONSTITUTION: A session flag unit(150) receives flag data from a digital unit(200). The session flag unit stores the flag data. The flag data includes information about a data processing state of an RFID tag. When power is temporarily turned off or on while storing the flag data, the session flag unit restores the stored flag data. The session flag unit provides the restored flag data to the digital unit. |
