Using anything with NFC as a Tesla Key?

[MOE J]

rings are not 100% reliable but they are convienent, i suppose if you buy an extra card, cut/remove the chip then re-insert it into ANYTHING (bracelet, earing, coin shell, neclace, name badge,etc) it should work.

The rings you can buy are literally a Tesla NFC card cut up and put into a ring. If you trust the card, why would you not trust the ring?

I'm still wanting to know what conspiracy or tracking threat the OP was under that makes BT not useful, while also activley wanting to use an iPhone and the Tesla app while at the gym.
