Embodiment 1

[0041] This embodiment provides a smart card control method, such as figure 1 It is the main flowchart of the present invention, and the smart card includes a bluetooth circuit and an IC chip, wherein the working process of the bluetooth circuit includes the following steps:

[0042] Step 11: the Bluetooth main control module of the Bluetooth circuit receives the access signal;

[0043] Step 12: judge the access signal type;

[0044] The type of access signal includes a button power-on signal, an external card reader device reading signal or a charging signal, and the Bluetooth circuit judges the type of access signal;

[0045] Step 13: According to the type of signal accessed, the Bluetooth circuit controls the work of the smart card, including the following processing steps:

[0046] According to the type of access signal, control the work of the smart card, where the type of access signal includes a button power-on signal, an external card reader device reading signal or ...

Embodiment 2

[0051] This embodiment also provides another smart card control method, figure 2 is the flowchart of the method, such as figure 2 As shown, the method includes the following processing:

[0052] Step 401: Detect whether the bluetooth circuit is turned on based on the button operation, if yes, execute step 403, if not, execute step 420, and turn off the bluetooth circuit;

[0053] Step 403: the bluetooth circuit performs bluetooth broadcast;

[0054] After executing step 403, execute step 406: judge whether the Bluetooth connection is successful, if the connection is successful, then execute step 407: judge whether there is a financial transaction operation, if the connection fails, execute step 408: perform connection timing; after executing step 408, execute Step 409: Determine whether the connection timing is timed out, if it is timed out, turn off the bluetooth circuit, if not, return to step 403.

[0055]After step 407 is executed, if there is a financial transaction,...

Embodiment 3

[0062] Embodiment 3: This embodiment also provides another smart card control method, image 3 is the flowchart of the method, such as image 3 As shown, the method includes the following processing:

[0063] Step 401: Detect whether the Bluetooth circuit is turned on based on the button operation, if yes, execute step 403, if not, execute step 402;

[0064] Step 402: Detect whether the smart card is connected to the charger, if yes, execute step 404, if not, control the bluetooth circuit to turn off;

[0065] Step 403: The Bluetooth circuit performs Bluetooth broadcast; after step 403 is executed, step 406 is executed.

[0066] Step 404: Check the charging status, if the battery is fully charged, turn off the Bluetooth circuit, if the battery is not full, then perform step 405: judge whether the user stops charging, if yes, turn off the Bluetooth circuit, otherwise return to step 404.

[0067] Step 406: Determine whether the Bluetooth connection is successful, if the conne...
