Have you maybe tried to open the website on a desktop pc? Maybe it will give you other options e.g. Apple wallet, which would result in a PKpass file? There has to be some way for apple users. Or maybe ask a friend with an Iphone to open it, try to download it and if it is a pkpass send it to you?

And yet another question, if I send an email asking the transportation authority what kind of technology they use for travel documents, if they provide any alternative to google or any way to download the ticket in either pkpass format or any other format that doesn’t require me to give my personal data to a data grabber, if they provide plastic travel cards to people that won’t allow their data to be used by google, what are the chances they won’t ignore me or outright laugh at me?

50:50 tbh, either you get someone who had bad experience with privacy laws (or something where privacy laws were severely misunderstood and resulted in a worse product because people didn’t check things properly. That is how it often goes in my experience.). Or you get someone who understands your problem and can help you.

I just learned what a pkpass file because some of you seem to know this technology, but ain’t it an apple technology?

while pkpass files are developed by Apple they can be used on Android with several Apps (i think they might be even usable with Google Wallet but i am not sure.). So often times when something can be added to the wallet i just click the Apple button, get the file and add it to my app. (In Germany, usage spread depends heavily on the region. Big city events often have wallet links for tickets etc.)
