摘　　要：设计了智能金融终端中磁条卡读卡器在SEP4020嵌入式微处理器上的Linux驱动程序,并详细叙述了该驱动的设计思路。磁条卡读卡器运用M3-2200F/2F解码集成芯片进行磁信号的硬件转换,用SEP4020作为主处理器,实现了磁条卡读卡器的刷卡、数据采集、处理、校验等功能。This article designs the Linux driver of magnetic card reader based on the embedded MCU SEP4020, which is used in the intelligent financial terminal, and gives the design ideas of the driver in detail. The magnetic card reader uses the F/2F decoding IC chip of M3-2200 to convert the magnetic signal, with SEP4020 as the host processor. As a result, the magnetic card reader realizes the functions of card brushing, date collecting, processing, checking, and so on.
