## What is Imprint Signet?

Imprint Signet is your personal anti-counterfeit studio: issue tamper-proof NFC tags for anything you make, sell or collect — and let every item prove itself.

ISSUE TAGS NO COPY CAN REUSE
Create a batch, hold a blank NTAG 424 DNA tag to the top of your iPhone, done. Each tag is programmed with a unique cryptographic credential that lives only inside the chip's secure element — it can never be read out, cloned or reused, so a copied tag can never pass as genuine. One issued tag consumes one credit; credit packs are one-time consumable purchases — no subscription, no auto-renewal, and unused credits stay on your account.

BUYERS NEVER NEED THIS APP
Anyone with an NFC-capable iPhone can simply tap your tag: it opens a web page showing the product's provenance and an authenticity verdict computed from the tag's secure credential. In-app tap-to-verify is also available and always free and unlimited.

MANAGE YOUR ISSUE
Track batches and product info in one place. No feed, no catalog, nothing publicly browsable — a product record surfaces only when someone physically taps the matching tag. Sign in with email or phone, and delete your account any time from inside the app.
