When the data includes five pieces of information, the processor stores one piece of information in one code image based on the number of at least one piece of information included in the data, so that a total of five code images (eg: code images corresponding to 711, 713, 715, 717, and 719 of FIG. 7) may be generated. When the processor generates the five code images, code images including specific information (eg, code images corresponding to 713 and 717 in FIG. 7 ) and code images including information excluding specific information ( Example: code images corresponding to 715 and 719 of FIG. 7) may be separately generated. In addition, the processor corresponds to the order of the code image including the specific information, but includes code images including default information excluding the specific information (eg, code images corresponding to 713' and 717' in FIG. 7) , to generate a total of 7 code images.

The processor of the electronic device may display, among the plurality of code images, a first code image (eg, the code image 711 of FIG. 7 ) to be displayed in the first order in a designated area of the display included in the electronic device. (eg, the display 202 of FIG. 2 ) may be displayed in a designated area. While the processor is displaying the first code image through the display in the designated area, the external electronic device may scan the first code image. The processor may receive a first designated signal from the external electronic device. The first designated signal may include information on the external electronic device (eg, address information of the external electronic device or information on a user account).

In state 730, the processor of the electronic device may receive a specified signal from the external electronic device that has scanned the code image 731 (eg, the code image 711 of FIG. 7 ) corresponding to the first order. The processor determines whether the external electronic device is a device capable of acquiring code images 733 and 737 (eg,

code images

713 and 717 of FIG. 7 ) including specific information, based on the received specified signal. can judge

code images

733 and 737 including the specific information among the plurality of code images in the designated area; Code images 735 and 739 (eg,

code images

715 and 719 of FIG. 7 ) including information excluding the specific information may be sequentially displayed in the designated area.

According to an embodiment, the usage right information for specific information included in the first code image corresponding to the first order (eg, the code image corresponding to 731 in FIG. 7 ) is the address of the external electronic device (eg, Mac). address) is set to specified information (eg, 14235463), the processor determines that the specific information It is possible to identify whether the device is capable of obtaining . When the address of the external electronic device included in the specified signal (eg, the Mac address of the external electronic device) matches the specified information, the processor identifies that the external electronic device is a device capable of acquiring specific information. can In addition, when the processor receives the first designated signal from the external electronic device, the processor selects a communication channel formed based on information on a communication method included in the first code image (eg, when set to Wi-Fi). It is possible to receive the first designated signal through.

The processor of the electronic device, which has identified that the external electronic device is a device capable of acquiring specific information, includes specific information in the next order of the first code image corresponding to the first order displayed on the designated area of the display A second code image (eg, code image 733 of FIG. 7 ) may be displayed. When the processor receives a second designated signal through a Wi-Fi communication channel from the external electronic device that has scanned the second code image while displaying the second code image, the second code image corresponding to the next sequence A third code image (eg, code image 735 of FIG. 7 ) may be displayed in a designated area.

Thereafter, when the processor displaying the third code image receives a third designated signal from the external electronic device through a Wi-Fi communication channel, a fourth code image including specific information in the designated area (eg: The code image 737 of FIG. 7 may be displayed. Additionally, when the processor displaying the fourth code image in the designated area receives a fourth designated signal from the external electronic device, a fifth code image (eg, the code image 739 of FIG. 7 ) is displayed in the designated area. can be displayed

On the other hand, in state 750 , the processor of the electronic device may identify that the external electronic device is a device that cannot acquire code images including specific information (eg,

code images

713 and 717 of FIG. 7 ). , code images (eg, in FIG. Corresponding to the order of the

code images

713 and 717 of 7, but including the code image 755 (eg, the code image 715 of FIG. 7 ) including default information other than the specific information, the code including the specific information It can be displayed instead of an image.

Since the processor determines that the external electronic device is a device that cannot obtain specific information, the processor includes default information corresponding to the order in which the code images including the specific information are displayed in the order in which the code images including the specific information are displayed code images can be displayed in the designated area.

According to an embodiment, the usage right information for specific information included in the first code image 751 (eg, the code image corresponding to 711 in FIG. 7 ) corresponding to the first order is a user account. If it is set to specified information (eg, samsung12) in relation to , the processor determines which account is logged into the external electronic device based on the information about the user included in the first specified signal received from the external electronic device. You can determine if it is an account.

When the account logged into the external electronic device does not match the specified information, the processor of the electronic device may determine that the external electronic device is a device that cannot obtain code images including specific information. After determining that the external electronic device is a device that cannot obtain the code image including the specific information, the processor scans the first code image (eg, the code image 711 in FIG. 7 ) corresponding to the first order. When receiving the first designated signal from the external electronic device, the code image 753' including default information, not the code image 753 (eg, the code image 715 in FIG. 7 ) including specific information (eg, the code image 753 ') : The code image 713' of FIG. 7) may be displayed as a second code image in the designated area. When the processor receives the second designated signal from the external electronic device through the Wi-Fi communication channel, a code image 755 including information excluding specific information as a third code image that is the next order of the second code image (eg : Code image 715 of FIG. 7) can be displayed.

Thereafter, when the processor receives the third designated signal from the external electronic device, the code image 755 including information excluding specific information, which is the third code image displayed in the designated area, is converted into a fourth code image. It can be displayed as a code image 757' (eg, the code image 717' of FIG. 7) including default information. Additionally, when the processor of the electronic device receives the fourth designated signal from the external electronic device, the code image 757 ′ including default information displayed as the fourth code image in the designated area is the fifth code image. A code image 759 (eg, the code image 719 of FIG. 7 ) including information excluding specific information may be displayed in the designated area.
