In some embodiments, the control chip has a first control interface and a second control interface that is different from the first control interface;

the first controlled switch is connected with the second control interface;

The first controlled switch comprises a first connecting end, a second connecting end and a third connecting end, and the first connecting end is connected with the control chip; the second connecting end is connected with the electronic identification card; the third connecting end is provided with a second controlled switch; the first controlled switch is used for switching the first connecting end and the second connecting end to be communicated or switching the first connecting end and the third connecting end to be communicated. That is, the connection between the control chip and the second controlled switch is disconnected when the control chip communicates with the electronic identification card; when the control chip is communicated with the second controlled switch, the connection between the control chip and the electronic identification card is disconnected.

The control chip controls the two connecting ends of the first controlled switch, which are connected with the control chip and the second controlled switch, to be switched into communication. That is, the first controlled switch switches the first connection terminal and the third connection terminal to be connected; the control chip is communicated with the second controlled switch. And the control chip controls the two connecting ends of the second controlled switch, which are connected with the second clamping seat and the first controlled switch, to be switched into communication.
