Method and system for updating RFID tag value of transferred object

A system for updating an RFID tag value of a transferred object, the system comprising:

• a first communication unit receiving a first RFID tag value extracted by reading the RFID tag from an RFID reader of a transferor of an object with an attached RFID tag, and an open RFID value deciphered from the first RFID tag value;
• a first detection unit extracting a second RFID tag value from the RFID tag attached to the transferred object;
• and
• an updating unit receiving the first RFID tag value and the open RFID value from the communication unit, receiving the second RFID tag value from the first detection unit, determining whether or not the first RFID tag value is the same as the second RFID tag value, and if it is determined that the first and second RFID tag values are the same, updating the second RFID tag value of the RFID tag attached to the transferred object, with a new RFID tag value, by using the first RFID tag value and the open RFID value.

A system for updating an RFID tag value of a transferred object, the system comprising:

• an RFID reader of a transferor disposed in the transferor side of the object with an attached RFID tag, reading the RFID tag of the object, extracting a first RFID tag value, and generating an open RFID value from the extracted RFID tag value;
• an RFID reader of a transferee disposed in the transferee side of the object, receiving the first RFID value and the open RFID value, extracting a second RFID tag value from the RFID tag attached to the transferred object, determining whether or not the first RFID tag value is the same as the second RFID tag value, and if it is determined that the first and second RFID tag values are the same, updating the second RFID tag value of the RFID tag attached to the transferred object, with a new RFID tag value, by using the first RFID tag value and the open RFID value;
• and
• a network transmitting the RFID tag value and the open RFID value from the RFID reader of the transferor to the RFID reader of the transferee.
