How to integrate a standalone, non-ESP32 NFC tag reader?

I’m having a hard time conceptualizing how the Tags integration is supposed to work with standalone tag readers outside of the ESPHome ecosystem.

I’m building a device for my home based on a Raspberry Pi Zero 2 W, and would like to integrate a NFC reader if possible: scan a tag on the device to trigger automations within Home Assistant via the Tags integration.

If I were building off of an ESP32 board, I’d follow the excellent instructions for adonno’s tag reader. Without that, plugging a reader directly into my Home Assistant server, or using the mobile app, however, I’m uncertain how to get the data from the Pi to HA.

Is this possible? If so, how?
