Abstract: Generally, a computing device displays, on a display device of the computing device, a barcode to be read by a scanning device. When a barcode is displayed on the display device a determination is made as to whether the barcode is not fully displayed on the display device due to hardware of the computing device such as a punch hole in the display device for a camera, speaker, or microphone. If the barcode is not fully displayed due to the hardware of the computing device, the display of the barcode is modified so that the barcode is fully displayed on the display device despite the hardware of the computing device. Additionally or alternatively, if the scanning device has not completed the scan within a threshold amount of time, the display of the barcode on the display device is modified, such as by increasing or decreasing the resolution of the barcode.
