The invention discloses a method and a system for storing and displaying data by using a QRCode two-dimensional code. The method comprises the following steps: S1, the large-capacity data is collected through a software system or equipment; S2, the software system or equipment performs segmentation processing on the data according to the required encryption / original text and the word number set by the parameters, and identifies the current page number, the total page number, other parameters and other information; and S3, the software system or equipment sets the segmented data according to the sequence of serial numbers, carousel frequency, time length and the like to generate a plurality of two-dimensional codes. The invention relates to the technical field of storage and display of large-capacity data, in particular to a method and a system for storing and displaying data by using QRCode two-dimensional codes, which add a new application scene: an APP (Application) calls out a two-dimensional code moving graph, and offline verification data, such as application scenes of identity card information, images, file contents and the like, such as access control security authentication, data transmission and the like without network connection, so that the method can be well applied to some areas where the network is limited.
