wherein the smart card is in a connection state with the electronic device;
specifically, the connection mode between the smart card and the electronic device may be wireless connection, that is, the smart card and the electronic device write data in a wireless communication mode.
The first instruction may be an AT instruction, and specifically may be in the form of an active reporting instruction, where the active reporting instruction refers to an active mechanism of the SIM card, that is, the SIM card may actively initiate an operation executed by an ME (Mobile Equipment).
For example, through the SET UP MENU command, the SIM card will provide a SET of MENU items to add to the ME's original MENU system for the user to choose from.
Specifically, the first instruction controls a display screen of the electronic device to display the title of the smart card and menu items, wherein the menu items comprise a plurality of submenu items, and each submenu item can correspond to one function. A typical SIM card menu is shown in table 1 below:
TABLE 1
The above menu is a certain SIM card STK menu in practical application, where each menu item has a corresponding function, and the function is presettable and programmable, and after entering the STK menu, a user can select different submenu items for operation. In this example, "Recharge" means "Recharge", the user can perform a Recharge operation, "solution" means "promotion", the user can obtain promotion information, "Weather" means "Weather", the user can obtain Weather conditions, "News" means "News", the user can obtain News contents, "Input" means "Input", the user can Input contents in a specified range, and so on, and in practice, clicking different menu items of the SIM card can realize corresponding preset functions.

specifically, based on the sub-menu item selected in step S305, the data packet is written into the smart card, and the AT command may be used to input the data packet, for example, the get input command.
It should be noted that, writing the data packet into the smart card is to write the data packet into the smart card as a whole, and not to write the data contained in the data packet into the corresponding position after opening the data packet.
In the following embodiments, how to write the saved data into the corresponding location in the smart card will be described, which is not described in detail in this embodiment.
Step S307: and storing the data packet to a preset storage area of the smart card.

steps S401 to 403 are the same as steps S101 to 103 in embodiment 1, and are not described in detail in this embodiment.
Step S404: receiving operation information;
it should be noted that, when writing the data packet into the smart card, the relevant content may be upgraded for the smart card operator, but the operation process of the smart card is normal, and synchronous upgrade is not needed, and accordingly, the data packet related to the upgrade may be written into the smart card, and when necessary, the data packet may be reactivated or the data writing into the smart card is completed.
Wherein the operation information is a process of operating the electronic device by a user so that a smart card connected with the electronic device is activated or writing is completed.
Specifically, the operation information may be input by a user through operating an input structure provided in the electronic device, where the input structure may include a mouse, a keyboard, a touch screen, a stylus pen, a touch pad, and the like.
Step S405: reading the data to be written from a storage area according to the operation information;
wherein, the storage area stores the data to be written.
Since the data to be written is already stored in the storage area of the smart card, the data to be written is read out from the storage area at this time.
In specific implementation, after the data to be written is read from the storage area, the data to be written stored in the storage area may be deleted, or may also be directly overwritten when other data to be written is continuously stored in the subsequent step.
Step S406: and writing the data to be written into a first position of the smart card.
The first position refers to a corresponding position of the data to be written in the smart card.
It should be noted that the input data is automatically stored in the Edit Buffer (cache) of the smart card in a variable form, and there is no clear definition in this embodiment where to write the data into the smart card.
For example, when the data to be written is the authentication key, the corresponding location may be a storage area for storing the authentication key; when the data to be written is a command encapsulated by an APDU, the corresponding location may be a storage area storing the command.
In summary, the method for writing data into a smart card provided in this embodiment further includes: receiving operation information; reading the data to be written from a storage area according to the operation information, wherein the data to be written is stored in the storage area; and writing the data to be written into a first position of the smart card. By adopting the method, after the data packet is written and stored in the intelligent card, the data in the data packet is written into the corresponding position in the intelligent card according to the triggered operation information, the time for writing the data into the intelligent card is selected by the user, and the user participation degree is higher.
