摘要： A system for updating a radio frequency identification (RFID) tag value of a transferred object is contemplated. The RFID tag is updated by having a transferor's RFID reader read an RFID tag attached to an object being transferred and extracting a first RFID tag value. An open RFID value is deciphered through the extracted first RFID tag value. Then, the transferor's RFID reader transmits the first RFID tag value and open RFID value to an RFID reader of a transferee who is receiving the object having the attached RFID tag. The transferee's RFID reader extracts a second RFID tag value of the RFID tag of the transferred object. By using the received first RFID tag value and open RFID value, the second RFID tag value is updated. Accordingly, even using RFID, the property rights of an object having an attached RFID tag can be transferred while maintaining security.
