To use this component, use the block on your screens and send an alphanumeric string to the Input variable to display a barcode of that variable. Use the IMG block for raster-based barcodes, and the SVG block for vector based barcodes. You can also customize the format, height, width and whether or not to display the barcode value on the barcode. See https://lindell.me/JsBarcode/ for further documentation.
