Abstract: The present application provides a data sharing solution. In the solution, a first application running on a first user equipment uploads shared data, and a shared device generates a two-dimensional code for the shared data and returns the two-dimensional code to the first application. The first application can provide the two-dimensional code to a second application running on a second user equipment. After scanning the two-dimensional code, the second application can send a data obtaining request to the shared device based on the scanned information, so the shared device sends the shared data corresponding to the two-dimensional code to the second application based on the request, thereby completing cross-application data sharing. The process offers convenient data transfer for the user and also breaks through limitations of data compatibility between the different APPs and alleviates a problem that information between the different APPs cannot be mutually identified.
