The USPS shouldn’t be trusted! Hence shipping insurance…
Where is this coming from?
I’m a lost & found expert, you’re welcome… After managing L&F at more than 70 major festivals and events, along with several arenas and colleges, we always get the question/demand/statement with an upwards inflection of well, “can’t you just drop my ID in the mail.”
This myth plagues us on a regular basis and typically results in a hair tearing out frustration scream of “Are you nuts?!??!?!”
Where did this start?
We went back to try and find out why anyone could want this. The best source we’ve found is a Lifehacker Article and a Reddit Thread both from 2013. — Ah 2013, a wonderful time before everything was being hacked and no one had a care in the world about information security —
Funny enough, in that Reddit Thread a relative expert immediately shoots down the idea.

Ya… but why should we trust you?
We are taking this transparency even further by building connections so the “finder” will be notified and, optionally, can connect to the “loser” when an item is returned. Is that trustworthy enough?
