Und keine Frage, \"Die Tarifsysteme sind ein Folterwerkzeug des frühen 20. Jahrhunderts\" ([kritisiert Mobilitätsforscher Andreas Knie](https://www.spiegel.de/auto/aktuell/deutschland-in-diesen-staedten-ist-der-nahverkehr-am-guenstigsten-a-1298823.html)). In mehreren Verkehrsverbünden werden daher sog. Check-in / Be-out (CiBo)-Systeme getestet: Apps, die automatisches Bezahlen per Handy ermöglichen und rückwirkend nach einer oder mehreren Fahrten die optimale Fahrkarte auswählen können.\n\nDoch wie funktionieren solche Systeme eigentlich? Aufgrund einer Schwachstelle konnte ich mich im Backend eines CiBo-Systems umsehen. Die Einblicke werde ich in diesem Vortrag in Form eines Bildschirmvideos teilen.","original_language":"deu","persons":["kantorkel"],"view_count":8837,"promoted":false,"date":"2021-12-28T16:00:00.000+01:00","release_date":"2021-12-29T00:00:00.000+01:00","updated_at":"2026-02-05T11:45:12.767+01:00","tags":["rc3-2021","361","2021","Chaosstudio
