AI Technical Summary
Technical Problem
Existing order information provision methods using QR codes and NFC require real-time network connections and high-spec devices, leading to delays and increased costs, and lack effective authentication for changing customer scenarios.
Method used
A timestamp-based dynamic information system that generates and verifies QR codes and NFC data without external updates, using encrypted timestamps and salt values pre-embedded in order terminals, allowing authentication and information access without network reliance.
Benefits of technology
Enables secure, non-face-to-face ordering with dynamic information updates, preventing unauthorized access and reducing system construction costs by eliminating the need for additional communication devices.

Abstract
The present invention relates to a method for providing order information using timestamp-based dynamic information, which is performed by a server, and includes: (a) receiving dynamic information from a user terminal; (b) decrypting the received dynamic information with a secret key corresponding to the dynamic information to extract the timestamp of the dynamic information; (c) verifying the validity of the dynamic information by comparing the timestamp with the server's time information; and (d) if the dynamic information is valid, providing the user terminal with Internet resource address information corresponding to the dynamic information.
