I tried a year or so ago to add my iPhone 12 Pro to my access control system. I was to grab ids from the phone and add them to user records. I was never able to get them to work. Today for no good reason I tried with the same iPhone and os 15.5. I was able to unlock my doors. It took multiple attempts as the iPhone cycled through ids before it hits the matching id in my access control software. I was pretty surprised and I'm now wondering how to get it to use correct sooner/consistently. While attempting to gain access my Apple Card is the visible card in the interface... I'm opening to trying any ideas.
