The present disclosure discloses a mobile scanning device for retrieving stress information of one of a plurality of reinforced glass panels. The device includes an image capturing device to capture an image of an identification code installed on a surface of the one of the plurality of reinforced glass panels, an image processor to process the captured image and recognize the identification code, a central processor to instruct the mobile scanning device to retrieve stress information corresponding to the identification code from a glass panel production information database, and a display device to display the retrieved stress information. The stress information was obtained via at least one stress sensor testing a stress at different testing locations on a surface of each of a plurality of glass panels being processed on a production line for manufacturing the plurality of reinforced glass panels.
