IC card reading apparatus and its related method |
摘要 |
One purpose is to provide a user friendly IC card reading apparatus conforming to different communication standards. A linear power amplifier supplies an antenna circuit with a power source voltage for Type A which is supplied from a power supply switching circuit when transmitting a radio signal of Type A, while supplying the antenna circuit with a power source voltage for Type B which is supplied from the power supply switching circuit when transmitting a radio signal of Type B, based on the instructions of a CPU. This makes it possible to read out of IC cards of both Type A and Type B.
