In order to do that, first, download and install a barcode font, this one will do the trick (and is free).
Once installed, start your Composer, and use that font like any other fonts in a Text Asset.
Mix it with the usual Intuiface power features (binding, triggers/actions) and you’re good to go!
Here is a “1 minute-build” sample using a Text Input.
