I'm planning to create an integrated app that enable to show your transit fees and stations which you get on/off at.
I could scratched out parts of my app that analyze and parse values that NFC bundled transit card stored.
However I could not find out the way how to use some data stored in transit card of iOS Wallet app. I can see transit information in the Wallet app which I want to use, also there are some document which might shows possibility I could handle these data, https://developer.apple.com/documentation/passkit/pkstoredvaluepassproperties .
I'm not really sure it is possible to use(read) these data in my iOS app via using PassKit. If you find some apps which using kind of data, could you please share me some existing app link, or tell me guides or documents which shows roughly how to use PassKit classes / methods.
