Zusammenfassung:The invention discloses an offline two-dimensional code information storage system and method, and belongs to the technical field of two-dimensional code application. The system comprises a user terminal, the self-service terminal is used for storing invoice information and establishing a database for storing the invoice information, and after a user requests the self-service terminal to make an invoice, the user terminal calls the invoice information, stored in the database, of the user and generates an offline two-dimensional code according to the invoice information of the user; the service party verifies the identity of the user after the user scans the two-dimensional code, authorizes the user after the verification is completed, analyzes the offline two-dimensional code scanned by the user to obtain the user invoice information stored in the offline two-dimensional code after the user authorization is completed, and sends the user invoice information to the service party; and returning the user invoice
