The first thing to test when barcodes are not scanning properly into All Orders Mobile is whether or not the scanner has been configured to properly scan and add a terminating character, in this case a carriage return character. To tun a quick test open the Notepad application on the device and try to scan the barcode. If the barcode is input into Notepad correctly and the cursor moves to the next line then your scanner is properly configured. If not please refer to the instruction manual from your scanner or contact the vendor from whom the scanner was purchased for support.
