I am implementing "add a card to the wallet" button and I am able to finish it but I have a problem identifying cards in the system... I need to add into pass some additional data like customer id or whatever and I found userInfo in apple doc
and I played with that but I wasn't able to add or get any data from this object. Is it probably just a getter.
How can I put some data into userInfo object? It has to be part of BE or how?
