Yeah, I have no idea how these tags are actually being used, let alone why they could be useful.

NFC tags can be scanned using a phone. An app on the phone can then detect the action and act accordingly. The phone can differentiate between different tags.

I use an NFC tag to lock the house using Home Assistant.

OK. Why not just tap "lock the house" on your screen? Or use a voice interface (which requires zero extra hardware)?

I like the hardware aspect, it feels very intentional and deliberate for context switching.
