Abstract

Smart card system is being used in many countries to improve access to their transportation systems. Especially for subway system that typically see high volumes of passengers at specific times of the days, it's critical to find a ray to collect fares without unnecessarily delaying passengers. The card consists of antenna, modulation and demodulation block, power supply module and memory. The antenna receives the power and data signal from reader. The FRAM is used as the inner memory. And it is a non-volatile memory and complements the problems, that is high consumption and low data processing speed, of using conventional EEPROM in the passive smart cart. In this paper, we analyze and design the RF passive smart card to apply to the fare collection for the subway gate system.
