This application discloses method, an apparatus, a storage medium, and an electronic device for bar code generation and display. The method includes: obtaining a target code by compiling a source code, the target code being self-contained executable code comprising target computer readable instructions and comprising logic functions, wherein the target computer readable instructions are executable by a processor; and generating a target bar code embedded with the target code by encoding the target code, wherein the target code comprises at least one of the following logical functions: a first logical function for allowing a scanning device with a read permission to run the target code, a second logical function for allowing the target code to be run within a validity period, and a third logical function for calling and configuring target hardware in the scanning device to execute a target operation.
