A Filter Design of RFID Middleware in the Progress of Updating Barcode to RFID

Abstract

In this paper, an effective filter in RFID data process is proposed. In the progress of updating barcode system to RFID system, many commercial systems need the RFID middleware transmitting the processed data of one commercial operation to the application business logic layer in one time automatically. In this way, the modification or change of some current commercial systems will be little, and cost is reduced. Read rate and real-time operation is also considered in our filter. And a novel time-marker is used in the filter design.
