One switch turns a Mrk into a search.
When something goes missing, the tag stops being an ID and becomes an appeal. Switch on Lost Mode and anyone who scans sees that immediately — where it was last seen, what to do, how to reach you. Every scan tells you where it happened. And if you want to put a reward behind it, that runs through us rather than through a stranger’s bank details.

of shareable poster
Held
until you confirm the return
Turn this on if it goes missing — scanners see a lost alert instead of the usual profile.
An ordinary profile — nothing unusual here.
A clear lost notice at the top of the page instead of an ordinary profile, the message you wrote, where and when you last saw it, and a way to message you straight away. Nothing about your identity unless you choose to share it.
Switching on Lost Mode offers you a poster immediately — the photo, the name, the last-seen line and a QR code that leads back to the tag. Sized for a WhatsApp status, an Instagram story, or Letter paper to print and put on a pole. It is free on every tier, because a poster carrying your Mrk into the neighbourhood is the best thing that can happen to it.
You can offer a reward and fund it up front. The money is held against the case rather than exchanged in a car park, and is released once you confirm the item is actually back. That protects both sides: the finder can see a real reward exists, and you are not paying out on a promise.

A reward is optional — lost mode and messaging work either way.
