By the way, you can trigger iOS shortcuts with NFC tags, so in principle you can trigger any functionality exposed as a Shortcut action. However, NFC recognition doesn’t always work as smoothly as one would hope.

It depends on the type and manufacturer of the NFC chip. I recommend using SLIX2 chips; they are a bit more expensive, but they work perfectly.
