Fig. 1 shows a flowchart of a method for identifying a two-dimensional code applied to a first user device according to an embodiment of the present application, where the method includes step S11 and step S12. In step S11, in the video call process of a first user and a second user, a first user device responds to a track drawing operation of the first user on a video stream of the second user, obtains a track drawn by the first user, determines an interception area according to the track, and executes a two-dimensional code identification operation on the interception area in the video stream; in step S12, if the identification is successful, the first user equipment processes the two-dimensional code information obtained by the identification.

In step S11, in the video call process of the first user and the second user, the first user equipment responds to the track drawing operation of the first user on the video stream of the second user, obtains the track drawn by the first user, determines an interception area according to the track, and executes two-dimensional code identification operation on the interception area in the video stream. In some embodiments, during a video call between a first user and a second user, the second user aims at a two-dimensional code of a second user device used by the second user at a front camera to be displayed to the first user, and sends the two-dimensional code to the first user device in a video stream mode, so that the two-dimensional code is displayed on a video picture of the second user displayed on the first user device, the second user does not need to exit the video call at all, and the second user does not need to provide the two-dimensional code to be displayed to the first user in a photographing or screenshot mode to the first user. In some embodiments, when the first user sees that the two-dimensional code is displayed on the video picture of the second user, the first user may perform a track drawing operation on the video picture through his finger (for example, the first user's finger is pressed at a certain position on the screen of the first user device, and the finger is moved in a state of being kept pressed), at this time, the first user device may obtain a track drawn by the first user, and in response to a track drawing end event corresponding to the track drawing operation (for example, the first user's finger is lifted from the screen of the first user device), determine a corresponding intercepting region according to the track currently drawn by the first user.
