There's nothing specific for Formidable and barcode scanning. You may be able to use a WordPress scanner plugin and integrate it with Formidable, if you have the dev skills. https://www.ukrsolution.com/Wordpress/WooCommerce-Barcode-QRCode-Scanner-Reader

If you wish to do it with formidable forms - create form, add text field, add some code to activate a field on page load so you don`t have to click it, activate camera (You can use dedicated keyboard = click scanner icon which activates camera and scans automatically when barcode / qr code is detected), add some code to auto submit the form, add redirect action so you land on appropriate page. Cheers.
