One NFC tag per person?

Configuration
1

I am probably overthinking this, but I am, so…

I’d like to be able to use NFC tags to identify people when they show up to do volunteer work with our organization. Each person will get an NFC tag (sticker, probably) and then badge in using an NFC reader posted near the door. Each time someone tags in, I want to indicate that they are present. When they tag out, I want to indicate they have left There are some workflow issues with this, but they don’t change the fundamental problem.

It seems that the HA model is for each tag to be associated with an action, and lots of people can use a tag to perform the same action. Am I able to turn this around and have the tag be strongly coupled to the person?

Thanks

p.s. I’m a relative HA newbie, but a long time developer and techy.

Possession is 9/10 of the challenge.

Each nfc tag toggles is own boolean.

Each user has their own nfc tag.

I think ios let’s each device have a unique action for a nfc, but android works differently.

Ok thanks. Sounds like that has to be a manual process. I will look into whether I can build a component to do that automatically.
