Haha is that what the datasheet for that antenna module says? 40mm? Haha fuckin bullshit any time one part of a two part system claims a particular performance without any specification for the other part.

Wait, why would someone call 911 in this context? If you think this is a real person wouldnāt you run over and put the ladder back in place? Or try to catch them?
It looks like the person who put the decorations called 911 themselves just to get a fun video

might multi post into 3d printing, but the question doesnāt really pertain to 3d printing, so I feel like Iāll get more attention hereā¦
Iāve been conscripted to help make a sort of physical validation token for a facebook sale groupā¦ I wont tell you what they sell, but its legal, usually not specifically against TOS but they get zucked a lotā¦ so they keep everything in DMāsā¦ but proving whoās a known entity vs some random is difficultā¦
they want me to make then " vouch coins" for when enough people of clout vouch for someone they can receive a physical tokenā¦
easy enoughā¦
but now Iām toying with the idea of embeding a NTAG into the coinā¦ which I can do nbd thats something I do from time to timeā¦
but what would be a way to BEST utilize this in an identifying manner?
I was initially just going to write some kind of unique funny meme or youtube link to each one and lock the tagā¦ probably record the UID alsoā¦(I have my doubts that non rfid peeps will be able to understand the UIDā¦
also in theory if they are copying the uid and sending it to potential buyersā¦ that info is no longer secure or uniqueā¦
thoughts?
comments on how Iām overthinking it?
I have decreed that in that facebook group, I shall receive the mod title of āmaster of coinā forthwith lol

Definitely a cheap ntag.
Why not individually write them to separate Google forms all linked to the same doc. It only asks for their handle or email and records it. Then you have an active ledger.
I need a bit more explanation but maybe?
My Samsung door lock didnāt really have a problem with battery life, rather battery strength. The lock works fine on four Aa batteries for well over a yearā¦ but the strength of the lock motor.is pretty shit after just a couple months. The bolt routinely gets bound up if the door isnāt closed just perfectly, and sometimes causes the whole lock to brown out in the process.
I made a simple update and I am super happy with the results.

If weāre talking about any ālawsuit cultureā country, then if you run over to put the stair back, you might become liable for any damages that person sustainsā¦
So we develop this pavlovian response to avoid helping anyone as much as we can.

if your definition of BEST = āthe most unhingedā:
then make the token out of an edible material, except for the ntag chip.
This way you can easily fall back to ye olde practice of biting the coin to see if itās real! 
There is no such a thing as overthinking!!
Next youāre gonna tell me about overengineering?
Nonsense!!
Jokes asideā¦
Just toss in an NDEF for a site. if youāre talking about facebook rfid newbs, thatās the easiest way to validate it.
if you want to overengineer a bit, on the site you can add a link to a plain app that checks the chipās UID against your database
if you dial a bit back, each NTAG might have an individual URI param that takes to a page with a pic of the holder.
Iām pretty sure the good Samaritan clause would protect them here
