After getting my shiny new Deutschlandsemesterticket from University I was so annoyed with the quality of the SaarVV app that I set out to put my train tickets into Apple Wallet - whether the train companies wanted me to or not.
What followed was several weeks of banging my head against the wall and googling various terms with "filetype:pdf" until I understood how they're encoded.
This talk is a highly condensed executive summary of the most interesting parts of that journey - from the surprising to the downright weird. Finally, I'll cover how you can issue your own train tickets - for fun and absolutely no profit!
