VisiRing turns a simple QR sticker into a recovery beacon. The moment someone scans your tag, you get a push notification with the scan location — and they see your contact details instantly, no app needed on their end. Stick a VisiRing tag on anything you'd hate to lose: • Bags & backpacks • Keys, wallets & tools • Luggage & travel gear • Pet tags & collars • Prams, bikes & sports gear HOW IT WORKS Create your VisiRing QR code in the app and attach it to your item. Whoever finds it scans the code with their phone camera — your chosen contact details appear straight away. They don't need the app or an account. You get an instant push notification, including where the scan happened, so you can get your item back fast. WHY VISIRING • No batteries, no Bluetooth, no subscriptions to keep a tag alive — a QR code never runs out of charge • Works anywhere in the world, on any phone with a camera • You control what the finder sees — share only the contact details you choose • Scan alerts arrive in real time with location, so you know when and where your item was found Lost doesn't have to mean gone. Tag it with VisiRing. Terms of Use (EULA) - http://apple.com/legal/internet-services/itunes/dev/stdeula/
