It is not an airtag. The payphone doesn't use a network of snitches to say where you are at all times. It is really bad to instill the idea that you are never private, it makes our surveillance situation worse and more accepted. Which i am sure hackernews and the EFF have plenty of articles to show why normal people need privacy.

> having a quarter and using a payphone to call mom

I had enough coins for 2 phone calls in a sealed envelope in my school bag for emergencies - probably still in the bottom of my bag wherever it may be.

> that’s an airtag

How so? Mom has no way to know where you are until you initiate the call. Isn’t a big part of the developmental point to have kids recognize they’re lost on their own and then ask for help from a friendly stranger? What’s the ‘no airtag’ scenario you imagine?

> if it involved asking a business (car service in my case) to let you use their phone, or already having a quarter and using a payphone to call mom... thats an airtag :)

No. An airtag works for your mom no matter if you want it or not, some payphone on the street places the agency about calling help into your hands.
