The protective case features anti-loss functionality with an independent ID, one item one code. Simply scan the QR code to view the owner's information without the need for following or subscribing. Laser-engraved characters are clear and easy to identify, with scratch and abrasion resistance. The engraved content remains clear and legible over time, ensuring the safe return of your pet from any unexpected adventures. This is a pet ID tag that can be modified at any time. As your address and phone number change, or as your pet ages and grows, you can modify it according to time and circumstances. It is not a GPS tracker, but if someone scans the QR code, it will send your pet's GPS location to your app backend, and you can also view the scanned location on the map. QR code pet ID tags are essential for ensuring the safety of pets. It is not only a protective case but also an anti-loss device.
