Using Built-in Barcode in Mobile App

On the settings screen, where the server address of the application is entered, the 'Use built-in barcode reader' option is checked. Then, when a barcode needs to be scanned at any stage of the application, a small window appears. The barcode to be read in this window can be entered manually. It is useful in cases where it is difficult to read the barcode with a camera or when it is not possible to use a camera.
