Alternatively, in the above example, the specific manner of performing the first identification process based on the sub-step 21 is not limited, and may be selected according to the actual application requirement.
For example, in one alternative example, the substep 21 may comprise the substeps of:
a first step of displaying the target two-dimensional code image in a first display area (a display screen area of the fee collection platform 100), wherein the first display area includes a two-dimensional code display area for displaying the target two-dimensional code image and a non-two-dimensional code display area for not displaying the target two-dimensional code image, and an area of the two-dimensional code display area is larger than an area of the non-two-dimensional code display area, and the two-dimensional code display area is surrounded by the non-two-dimensional code display area (so that the target two-dimensional code image can be displayed through the larger area for a target user to operate);

the first recognition sub-result and the second recognition sub-result are combined in the order of the first recognition sub-result being before and the second recognition sub-result being after, so as to obtain the first recognition result including the first recognition sub-result and the second recognition sub-result (for example, if the first recognition sub-result includes 0101101 as the first identifier information, and the second recognition sub-result includes 1111110 as the second identifier information, the obtained first recognition result may include 01011011111110 as the first identifier information).
