Serial Numbers Using Barcode Reader

Dear Sir.

All my items are serialized from the factory.
I need to know how can I enter the serial numbers to the system in easy way (like bar code reader).
I don’t want to enter the serial numbers manually, do you know how can I make the system read the serial numbers using a reader??

Best Regards.

Bar code scanners feed into the keyboard input. So just point the field in your screen and scan.

OK, I will try first using my mobile camera (I have barcode reader application), but how can I insert it to the system??
I didn’t find the way to insert it, it should be a button when press it, it allows you to start scanning.
