DESCRIPTION:Digital tickets from traffic associations are often stuck insid
 e their proprietary walled garden apps. But the neat thing about digital t
 ickets\, is that the barcode can be shown anywhere\, and still be valid. T
 his talk documents my efforts to reverse engineer various traffic associat
 ion's apps\, and my work on [Zügli](https://zügli.app) to make tickets w
 ithout tracking available to all.
