(English Abstract)
RFID is application field is very wide. For example, There is parking administration system, bookkeeper administration system etc. Such application system must do priority Carrier wave choice according to application purpose. If in case of Carrier frequency is low, awareness distance is short and Carrier frequency is high, awareness distance is very long. This uses in case awareness object is fast-moving. And it must be Tag's supply and demand's that is smooth. Even if development of system is completed, if Tag's purchase is difficult, developing item is not need. In this paper, we shows RFID system using EM4095 chip that is using 125KHz by carrier wave. EM4095 is high effectiveness chip of the low-power and circuit is very simple. It is possible to read with being write as that connect 4 lines with MCU. MCU used Atmega128. As result, we explained circuit and control programs for each part, and show Tag's ID reception that use Reader by picture.
