# Showcase The full XWUIBarcodeQRCode tour: the payload prefixes phones act on (URL, Wi-Fi join, vCard, mailto, tel, geo), the four error correction levels, the size and quiet zone scale, and centre icon branding with iconSize. It also shows a live 3D XWUI logo overlay on accent-token ink, then closes with theme aware colours and a live generator that uses setData plus getDataURL export.
