System Design for Food Forgery Prevention and Traceability Using RFID Technology

Nowadays, food safety has drawn increasing attention because of its importance, yet the cost spent on food forgery prevention is expensive and the system is hard to maintain, therefore a low cost system is worth developing. Based on the above fact, this paper proposes a system design for food forgery prevention and trace ability using RFID technology. The system's hardware section consists of RFID reader, antenna and tag, to reach the design goal and save the total cost, the following measures are taken: 1, to build a forgery prevention and trace ability system, 2, to compare different communication protocols and select a system based on ISO/IEC 15693 standard, 3, to develop key hardware section, such as, setting the EAS function, designing a 16-slot anticollision flow, tuning the value of antenna's Q factor and resonant frequency. Such system has a variety of applications such as wine and cigarette.
