A barcode-scanner works almost like a keyboard.

It depends on the model. Every one that I've used works exactly like a keyboard (at least as far as the computer is concerned)

$(document).on("scanButtonDown"

You probably want keypress, not scanButtonDown.

Look at the event object to determine the "key" that was pressed.

To determine when the entire code has been scanned, you might get an "end of data" key (possibly a space or a return) or you might have to just count how many characters are being input.
