PetHub's Classic Aluminum tag links a unique QR code to a digital pet profile and includes a free Basic option, with optional paid PetHub+ features. The lightweight aluminum exact SKU was in stock at a low checked price. It must be activated before use, and successful scanning depends on QR readability plus a finder's phone and network connection. The page did not publish a waterproof or IP claim, so it works best as a digital-information layer alongside directly readable identification.
