Abstract
A computer-implemented method includes receiving, by an electronic device, a two-dimensional code generation request from a user operating the electronic device, the electronic device comprising secure element; obtaining, by the electronic device, two-dimensional code generation data, wherein the two-dimensional code generation data comprises account data of the user and timestamp data of the electronic device; obtaining, by the electronic device, signature data based on a predetermined signature algorithm stored in the secure element; and generating, by the electronic device, a target two-dimensional code based on the two-dimensional code generation data and the signature data.
