JQuery - Barcode Scanner Detection

I have a USB scanner that is in keyboard mode. The jquery code here actually works surprisingly well.

Any scanner activity is written to the console.

My problem is that I cannot work out how to prevent barcode scanned data inserting into the current form input field as well.

Ideally, I would want scanned data to be sent to a hidden input field somewhere - so as not to interfere with a users typing.

I have tried e.disableDefault() in various places inside the function but it doesn’t seem to work.
