METHOD FOR OPERATING RFID DEVICE AND RFID SYSTEM INCLUDING RFID DEVICE

摘要

PURPOSE: An RFID system including an operation method of an RFID device and the RFID device is provided to improve data storage efficiency of the RFID device and system by partitioning data to save according to storage capacity of an RFID tag and saving partitioned data in the RFID tag. CONSTITUTION: An RFID(Radio Frequency ID) device(100) accesses RFID tags(200,300). The RFID device compares the size of data to save in an RFID tag and storage capacity of the RFID tag. If the size of data to save is bigger than the storage capacity of the RFID tag, the RFID device partitions the data to save. If the size of data to save is smaller than the storage capacity of the RFID tag, the RFID device writes the data to save in one tag. The RFID device writes data division information in each RFID tag.
