I write to you from Germany, where I work. I use an android device.
The transportation authority I am in is called Mainzer Mobilität and because my employer only covers 50% of the transportation costs if I use the digital travel card and not the physical one, I’m basically forced to use google wallet, which I hate. This transportation authority doesn’t offer pkpass files I could use with FOSS Wallet or pdf cards with my full name and a small qr code I could download. It has to be google wallet or use a physical card (and pay double).
I used to take a screenshot of the qr code and download the receipt as a pdf each month. On the receipt everyone can see the relevant data, including my full name, address, expiry date of the travel document, type of travel card and what I paid, but 5 days ago a “Kontrolleur” (an employee who boards buses to identify passengers without valid travel documents) fined me for not showing him the google wallet app with my pass there.
Yo read that right, it MUST be google wallet, otherwise I’m not carrying a valid travel document. The qr code alone together with the receipt with all my data and my identity card are not enough.
Is there any FOSS wallet or application that would work in Germany like google wallet does?
I really hate being forced to use google crap like this, I really don’t want to trust them with my data but I need to save as much as I can.
Feel free to suggest other communities where I could ask this question.


Sadly I don’t have access to the ride ticketing interface anymore. But I remember it was an option on their web interface to download the .pkpass file. It might have been named Apple pass or something. I didn’t scan a QR code to add the ticket to FossWallet.
Found this forum thread, it seems they changed a few things but you might still be able to get the .pkpass file
