the first card holder module 1 and the second card holder module 2 are both electrically connected with the main control module 3, and the first in-place detection pin 11 of the first card holder module 1 and the second in-place detection pin 21 of the second card holder module 2 are both electrically connected with the main control module 3;

The smart card can be inserted into the first card holder module or the second card holder module only, so that the identification and information interaction of the smart card can be carried out respectively, and the smart card can be inserted into the first card holder module and the second card holder module simultaneously, so that the identification and information interaction of the smart card can be carried out simultaneously.
Fig. 2 is a second structural schematic diagram of a card socket system according to an embodiment of the present application, and as shown in fig. 2, the card socket system 100 further includes a first selection module 4;
the first selection module 4 is connected to a connecting line between the main control module 3 and the first card holder module 1 and the second card holder module 2;
and the first selection module 4 is configured to select a conduction sequence of the first card socket module 1 and the second card socket module 2 with the master control module 3.
In application, when a first smart card is inserted into the first card socket module and a second smart card is inserted into the second card socket module at the same time, the first selection module is required to select the conduction sequence between the first card socket module and the control module and between the second card socket module and the control module. For example, during system production, according to actual requirements, the first card holder module may be set to be firstly conducted and then the second card holder module may be conducted, and the second card holder module may be set to be firstly conducted and then the first card holder module may be conducted. Meanwhile, the first card holder module and the second card holder module are connected with the main control module through the first selection module, so that interfaces can be saved for the main control module, and the card holder module is suitable for the condition that the interfaces in the card holder modules are limited.

Meanwhile, the first in-place detection pin and the second in-place detection pin are connected with the main control module through the second selection module, so that interfaces can be saved for the main control module, and the device is suitable for the condition that the interfaces in the card seat module are limited.

and the first conversion module 6 is configured to perform interface conversion or level conversion on the first socket module 1.
In application, when the main control module has no special interface or the special interface resource is insufficient, the first conversion module can be adopted to perform interface conversion on the input information of the first card seat module and then input the input information into the main control module; when the levels of the main control module and the first card holder module are not matched, the input information of the first card holder module can be input into the main control module after being subjected to level conversion by the first conversion module.
Because conventional smart cards can generally support three levels: 1.8V, 3.3V and 5.0V, but the interface of the main control module is not necessarily supported by all three levels, so when the card socket system needs to support a full class card, an additional level conversion chip is needed; meanwhile, the main control module does not necessarily support a dedicated Interface (e.g., a Serial Communication Interface (SCI) Interface) of the smart card, and since the SCI Interface includes level conversion and protocol analysis of an IC card Interface, if the main control module does not have a dedicated SCI Interface and needs to support the smart card, an Interface conversion chip needs to be additionally added, or a General Purpose Input/Output (GPIO) port of the main control module itself may be used to perform Interface simulation, and meanwhile, protocol analysis is added through software.
As shown in fig. 3, the card socket system 100 further includes, for example, a second conversion module 7;
the second conversion module 7 is connected to a connecting line between the second card holder module 2 and the main control module 3;
and the second conversion module 7 is configured to perform interface conversion or level conversion on the second socket module 2.
In application, when the main control module has no special interface or the special interface resource is insufficient, the second conversion module can be adopted to perform interface conversion on the input information of the second card seat module and then input the input information into the main control module; when the levels of the main control module and the second card holder module are not matched, the input information of the second card holder module can be input into the main control module after being subjected to level conversion by the second conversion module.

and S2, establishing communication with the first socket module according to the first interrupt signal, and/or establishing communication with the second socket module according to the second interrupt signal.
In application, a first interrupt signal of a first in-place detection pin is acquired, a first communication signal is sent to a first card holder module according to the first interrupt signal, communication is established between the first card holder module and the first card holder module, and information interaction is carried out between the first card holder module and a first smart card; the second interruption signal of the second in-place detection pin is acquired, a second communication signal is sent to the second card holder module according to the second interruption signal, communication is established between the second card holder module and the second card holder module, information interaction is carried out between the second card holder module and the second smart card, and therefore the first smart card and the second smart card can be identified simultaneously.

and S20, accessing according to the access sequence of the first interrupt signal and the second interrupt signal.
In application, the first interrupt signal or the second interrupt signal can be switched on first according to actual needs.

and detecting according to the interrupt detection sequence of the first in-place detection pin and the second in-place detection pin.
In application, the interrupt detection sequence of the first in-place detection pin and the second in-place detection pin can be set according to actual needs. When the first in-place detection pin is detected firstly and then the second in-place detection pin is detected, whether the first in-place detection pin generates a first interrupt signal is detected firstly, if so, the first interrupt signal of the first in-place detection pin is acquired, if not, whether the second in-place detection pin generates a second interrupt signal is detected, if so, the second interrupt signal of the second in-place detection pin is acquired, and if not, the operation is finished. If the second in-place detection pin is detected first and then the first in-place detection pin is detected, the detection process is opposite to the detection process.
