Problems solved by technology
[0002] The business of financial self-service equipment has the need to retain card picture data. The current common solution is to add a Gaopai module to the device. However, Gaopai has many disadvantages in retaining card picture data. First, Gaopai takes up a lot of space and this Self-service equipment like self-service equipment cannot develop into portable; secondly, Gaopaiyi is sensitive to light, and it is prone to problems such as overexposure and reflection that affect image quality; moreover, Gaopaiyi cannot avoid card fraud, and there are cards that are not business transaction cards. risk

Embodiment 2
[0037] as attached figure 2 , 3 As shown, a software method for a card scanning and reading module of a self-service terminal includes the following steps,
[0038] S1, process A loads the interface layer IDCM.dll, and calls the "ICC open device" interface;
[0039] S2, the interface layer starts the service layer IDCMServer.exe, and the service layer initializes the command queue; initializes the executor and completes the hardware initialization work; initializes the state machine Status, and queries the hardware status in real time when the device is idle;
[0040] S3, the interface layer instructs the processor C to process the instruction data and send it to the service layer;
[0041] S4, the service layer inserts the instruction into the complex instruction queue through the instruction preprocessor S after receiving the instruction;
[0042] S5, the executor fetches the instruction from the complex instruction queue, and organizes the execution result of the "ICC o...

The invention discloses a software system and method for a card scanning and reading module of a self-service terminal. The software system comprises an interface layer module and a service layer module. An interface of the interface layer module is called by an upper-layer application, and the instruction processor adds additional information to instruction codes; a first communication machine sends an instruction to the service layer module; a second communicator takes different measures on different types of instructions through the instruction preprocessor according to the received instructions, and inserts the instructions into a light instruction queue or a complex instruction queue; a state machine processes the light instruction queue, the actuator processes the complex instructionqueue, and an execution result is sent to the interface layer module through the second communication machine; sharing of physical channels and states is achieved, existing card reader codes and second-generation ID card scanning module codes can be reused by slightly adjusting an upper-layer application, and the development workload is reduced.
