Abstract
A check-in method based on a two-dimensional barcode and an associated system including a check-in management server, a scanning terminal, and a display terminal are provided. The check-in management server is communicatively connected to a display terminal and a scanning terminal, respectively. The check-in management server generates a two-dimensional barcode and sends the two-dimensional barcode to the display terminal, the two-dimensional barcode comprising a check-in identifier. The display terminal displays the two-dimensional barcode. The scanning terminal then scans the two-dimensional barcode, obtains a scanning timestamp and the check-in identifier, and sends a check-in request including a user identifier, the scanning timestamp, and the check-in identifier to the check-in management server. The check-in management server confirms the check-in request according to the check-in identifier and the user identifier, and records a check-in timestamp of the user according to the scanning timestamp.
