Yes, you can add a Form Calculation widget and set it up to capture the value from qr scanner as text. Here is a guide: How-to-Perform-Form-Calculation-Using-a-Widget

I mean how can after I scan the barcode or QR code, then the serial number pass to the text box above

You can do this with a condition. Here is one for your form:

okay, thank you very much

but cannot copy it into configurable list right?

I'm afraid that this is not possible with Configurable list widget, and that is because you can not map a specific field inside of the Configurable list widget.

Let us know if you need any further assistance.

thank you

but now I have question

We have moved your new question as separate thread: https://www.jotform.com/answers/1799643 

Can I know after click the Scan Barcode button, the reader box can be bigger?

Would you like to do this box bigger?

I suggest the following code. 

To inject into form itself:

iframe[src*='barcode'] {

  width: 550px !important;

}

To the widget:

How-to-Inject-CSS-Codes-to-Widgets

.video-container {

width: 550px !important;

}
