Abstract:
1. An apparatus for storing data of Radio Frequency Identification (RFID) tags having sensors, comprising: a controlling means for controlling the data from the sensors to be stored; and a storing means for storing the data from the sensors, wherein the storing means includes: a first storing unit which includes a kill password storage storing a kill password that an RFID reader transmits to an RFID tag in order to halt operation of the RFID tag, and an access password storage storing an access password of the tag; a second storing unit which includes an Electronic Product Code (EPC) storage storing a code for identifying an object having the tag, a protocol control storage having physical-layer information of the code storage, and an error check storage storing a Cyclic Redundancy Checking (CRC) code for detecting a transmission error; a third storing unit which includes a tag identifier storage storing a tag identifier including a manufacture model and a serial number of the tag; and a fourth storing unit which includes an initial sensor data storage storing initial information of the sensor, a real-time information storage storing information of year, month, day, time, minute and second, a maximum/minimum data storage storing maximum/minimum values compared to set up an excess/validity region of the sensing data, and a sensor data storage storing sensing data actually measured through the sensor embedded in the RFID tag.
