DATA ADMINISTRATION METHOD FOR RFID READER

摘要

PURPOSE: A data management method of a RFID reader is provided to stably transfer the data regardless of communications barrier by storing the data in a memory when the communications barrier is generated and promptly transferring the data to a host computer at a time after restoring the communications. CONSTITUTION: A data management method of a RFID reader comprises the following steps: transmitting(S10) a query command per a predetermined period; obtaining(S12) tag information by communicating with the tag; deciding(S14) whether communication failure between a host computer is generated or not; delivering(S16) the obtained tag information to the host computer in real time when the communications barrier is not generated; accumulating(S18) the obtained tag information in a memory when the communications barrier is generated; delivering(S20, S22) the stored tag information to the host computer promptly after restoring the barrier.
