CONTROL METHOD OF RFID TAG AND RFID TAG ADOPTING THE METHOD

摘要

PURPOSE: A control method of an RFID tag is provided to solve a fundamental failure by determining the expansion of the RFID tag. CONSTITUTION: If an approval command including a random number is received by an RFID reader, the RFID tag informs an RFID reader of a function expansion state while transmitting an OID(Object ID). The OID comprises PC(Protocol Control) information, a CRC(Cyclic Redundant Check) data, and an EPC(Electronic Product Code). The OID comprises an XPC(Expanded Protocol Control) information.
