Permanent QR Use Case

Smart QR Pet Tag

Locate lost pets instantly with location-aware collar tags.

The Problem

Traditional pet tags have limited space for contacts and cannot alert you if your pet is found. Web links on tags must never expire.

Why The Eternal Tier Responds Intentionally

Paid Eternal QRs are anchored on Base, so the last destination for the pet's contact page stays recoverable. The dynamic routing can request the finder's location and notify you immediately.

Cryptographic AnchoringUnlike the Free/Basic hosted tier, the paid Eternal tier writes an encrypted routing payload to Base L2. Eternal QR derives and exports a per-user recovery key so the last anchored destination can be decrypted without the Eternal QR servers. Basic operates on traditional infrastructure and does not include blockchain anchoring.

Real-world Example

A finder scans a dog's collar QR, shares their location, and the owner instantly receives an email with coordinates while the finder sees the dog's medication needs.

Future-proof your Smart QR Pet Tag

Stop leaving a critical digital legacy entirely in the hands of generic SaaS tools. Add Base anchoring and recovery-key export with the paid Eternal tier.
