Never again without it
I learned this the hard way. Last summer my drone went down somewhere over a field in Portugal — battery died, wind, gone. Weeks later I found out through a local Facebook group that someone had actually picked it up the day after. But there was no way for them to reach me, no name, no contact, nothing on the drone. By the time we connected, they had already given it away. Drone gone, footage gone, 900 bucks gone. With DRONE-QR that story would have ended after one scan: finder scans the sticker, I get a notification, done — without my phone number or address being printed on the drone for the whole world to see. Exactly the service I wish I'd known about a year earlier. The reward option is a smart touch too — gives the finder a real reason to do the right thing.
