The mobile device displaying the two-dimensional code can be a mobile phone used by a user when paying, and the two-dimensional code can be a payment two-dimensional code. After the mobile device is detected by the execution subject, the above-described distance information and angle information may be acquired by a displacement sensor provided in the reverse scanning device. The distance information may include, but is not limited to, coordinates of a relative position of the mobile device with respect to the back-scan device, a distance between the mobile device and the back-scan device, and the like, and the angle information may include, but is not limited to, an angle offset between the mobile device and the back-scan device.
