Low Cost System Design for Identification and Anti-Counterfeiting of Goods Using RFID Technology

Abstract

This paper proposes a system design for identification and anti-counterfeiting of goods using RFID technology. The system consists of RFID reader, antenna and tags, since most application systems are cost sensitive, different protocols are compared and then ISO/IEC 15693 is selected as communication protocol. By tuning the value of Q and by matching the resonance for both reader and tags, the systems performance has enhanced a lot especially for the distance of read and write. To search RFID tags easily, 16 slots anticollision is adopted and gives a command design flow. For the anti-counterfeiting, EAS method is used, by setting the related memory bit, EAS function is activated and can protect goods from stealing. Such system has a variety of applications such as libraries, asset management, logistics and so on.
