A sign-in method, system, scanning terminal, and display terminal based on two-dimensional code. The method comprises: a display terminal displaying two-dimensional code; a scanning terminal scanning the two-dimensional code, obtaining a scanning time and information used as a sign-in identifier in the two-dimensional code, and sending identifier information of a user, the scanning time, and the information used as the sign-in identifier to a sign-in management server; and the sign-in management server performing sign-in confirmation for the user according to the received information, and recording a sign-in time of the user according to the scanning time. Two-dimensional code used for sign-in is generated and displayed; and the two-dimensional code displayed by the display terminal is scanned, the information in the two-dimensional code is obtained, and the information is sent to the sign-in management server, so that the sign-in management server confirms and records sign-in of the user. Because two-dimensional code scanning is rapid and is unique, not only sign-in is rapid, but also the problem of sign-in replacement is not prone to occurring. |
