<p>PURPOSE:To obtain a portable storage medium device able to execute fare collecting processing simply and rapidly by providing a memory constituted enabling to rewrite data, reading and writing through space with a transmitted signal. CONSTITUTION:A receiving means 2 receives a signal transmitted through space. A decoding means 3 decodes whether the received signal is data writing command or the fare processing command and controls data writing/reading to a memory 1. In the case of the data writing command, data concerning with a period transmitted continuously and the data concerning with an amount are written in the memory. In the case of the fare processing command, a data reading means 5 reads the data written in the memory and a transmitting means 6 outputs the read data to the space. Thus, a portable storage medium device able to execute fare collecting processing simply can be obtained.</p> |
