Geocaching where a find is proven rather than claimed. Every hiding place holds an NFC tag that produces a fresh, signed code on each tap. Copying it down gets you nowhere, because yesterday’s code is worthless.
That removes the part of geocaching that otherwise runs on trust: if you are in the log, you were there.
Works in the browser, no app needed, straight from the tap. It is in closed beta, so there is no open sign-up yet.
