Non-contact IC card read-write method and system, computer equipment and storage medium

The invention relates to a non-contact IC card read-write method and system, computer equipment and a storage medium. The method comprises the steps that a command sent by an upper computer is received, the command is analyzed, and different communication modes are selected according to different use scenes; calling a corresponding command according to the selected communication mode to execute a corresponding communication protocol; when the radio frequency module detects that a signal comes from the main control module, parameter configuration is carried out, the parameter configuration comprises a card searching mode and a card reading mode, the card searching mode is a low-voltage low-power mode, and the card reading mode is a high-voltage high-power mode; and when the electric field transmitted by the transmitting antenna successfully activates the IC card, a communication channel is established between the transmitting antenna and the IC card for data transmission. According to the invention, under the
