Show HN: Simple Alternative to AirTags

This doesn't seem to solve the issue at all.

I have an AirTag in my backpack, one in my jacket and another on my keys. This is just a QR code that someone can scan to send me a message that they found my item? I can already put something in my jacket and backpack. If I lose my keys, I can't get into my apartment, so an AirTag is ideal for that.
