With the development of integrated circuits, SIM cards are increasingly used in people\'s lives, such as in the fields of mobile communications and finance. Therefore, SIM card detection has become a problem faced by suppliers and operators. This paper presents a design and implementation scheme for a card reading detection system platform based on ARM, explains the hardware circuit design and software design process, gives a hardware interface circuit schematic, completes hardware debugging, and proves that the scheme is feasible through testing.
