That was a time limited earlier ticket. "The tickets were valid for June, July, or August 2022. The offer aimed at reducing energy use amid the 2021–2022 global energy crisis." https://en.wikipedia.org/wiki/9-Euro-Ticket
It influenced the idea to come up with a permanent ticket: the "Deutschlandticket". It started 1. Mai 2023. https://en.wikipedia.org/wiki/Deutschlandticket
The Deutschlandticket costs max 49 Euros (next year it will cost 58€ per month) and is valid for one month for mostly all local®ional public transport systems (plus a few selected non-regional trains) in the whole of Germany. The subscription will renew automatically.
Companies often support employees by paying some of the costs. Then it typically costs 34.30 € per month. From next year on, employees pay 40,60 € per month max.
Here in my home city already 94% of the 213000 pupils use the Deutschlandticket for 0 € per month. Every pupil has free access to all of the country's local®ional public transport system... I find that kind of mind-blowing.
I have the ticket in my iPhone's wallet and thus also in the Apple Watch wallet. Additionally I need an ID card. Which at some point in time will also come to the smartphone. https://www.iamexpat.de/expat-info/german-expat-news/new-mob...
