Trusted-contact release
An emergency kit is no use if it’s locked behind a password only you know. The moment you most need someone to reach your medical directive or next-of-kin details is exactly the moment you can’t hand over a passcode.
You name one or more trusted contacts who can request release when you can’t respond. Set it to need their action alone, a quorum of several people, or a missed check-in — so the kit opens for the right person at the right moment, and stays shut otherwise.
