I just got my iPhone 11 pro max and wanted to see, if it can read the nfc enabled wrist band of my local gym. There are several nfc-apps on the app store and additionally the shortcuts app is capable of reading nfc-tags.
When scanning the wrist band with the shortcuts app, it is recognized. But every other app does not recognize it.
Are there different flavors of nfc? Is this just a iOS quirk? Is there a reason why only the shortcuts app can see this tag?
The local gym has some kind of nfc-based member-card. In fact its not a card, but a wrist-band with a tiny nfc-chip in it as it seems. The wrist band reader on the door is made by a company named "Gantner".
In the long run I want to get rid of this silly red wrist band and just use my apple watch. But I think this is not (yet) possible. Nevertheless I am curious to understand what is stored in this band and how nfc works in this case.
Update: Added Apps
