In step S201, when the user needs to use the function module of the smart card to perform a function operation, such as a payment operation, an authentication operation, and the like. A user sends a communication starting signal to a communication terminal through a key on the communication terminal, such as a mobile phone and the like, wherein the communication starting signal is a signal for the user to drive a functional module of the intelligent card to work by using the communication terminal.
The communication terminal receives the communication starting signal and transmits a wireless signal with a set frequency according to the communication starting signal.

Wherein the first set value is greater than the second set value.
Referring to fig. 3, a specific circuit structure is shown, wherein 123 is a conversion unit of the smart card, and 124 is a voltage stabilizing unit of the smart card;
when V isinWhen the voltage is less than the first set value, the first switch tube Q1 is in an off state, the control terminal of the third switch tube Q3 is in a high state, and the control terminal of the second switch tube Q2 is in a low state, so that the second switch tube Q2 and the third switch tube Q3 are both in an off state, V isinCharging capacitor C3 with a small current, VinGradually rising, the conversion unit 123 stops outputting the current to the voltage stabilization unit 124.
When V isinWhen rising above a first set value, VinAfter the voltage is divided by the first voltage dividing resistor R1 and the second voltage dividing resistor R2, the first switching tube Q1 is driven to be conducted, so that the control end of the third switching tube Q3 is in a low level state, the third switching tube Q3 is conducted, and V isinThe second switch Q2 is driven to be turned on after the voltage division of the third voltage dividing resistor R3 and the fourth voltage dividing resistor R4, so that the capacitor C3 outputs a large current, V, to the voltage stabilizing unit 124 through the converting unit 123inThe decrease is started. Meanwhile, the conduction of the second switch tube Q2 further reduces the conduction voltage of the first switch tube Q1.

In step S206, since the electric quantity of the driving electrical signal is greater than or equal to the set value, in order to ensure that the functional module can stop working in time after communication, the smart card stops receiving the wireless signal, i.e. stops converting the wireless signal into the driving electrical signal. Subsequently, it goes to step S207.
