Use cases
Every EdgeNFC tag answers the same question — "is this the real, un-cloned original?" — in whatever context you ship it. Below are the four we have written full playbooks for, and the test for whether a fifth belongs on the list.
The same engine every time. The playbooks differ in what the tap unlocks and what the page says afterwards. The cryptography underneath does not change from one use case to the next.
Playbooks
Each playbook covers what to tag, how to attach it, what the customer sees, and what it costs to run — including where the approach is weak.
Prove every garment is the real thing. Each tap is a fresh cryptographic proof a counterfeiter can't clone or reuse — and a resale market can check it years later.
See the playbook →Physical-to-digital provenance. Bind an item to its digital twin and its ownership record, verifiable across the whole lifetime of the object.
See the playbook →Clone-proof digital tickets and VIP passes. The monotonic counter defeats screenshots, relays and clones — and the door check is a single tap.
See the playbook →A tap that's provably you. Dynamic routing backed by a cryptographic identity rather than a copyable static link anyone can reprint.
See the playbook →The shared shape
If your problem fits this shape, it fits EdgeNFC — whether or not it appears above.
There is an object, credential or place whose authenticity has value to somebody: a buyer, a door, a resale market, a regulator.
A printed code, a hologram or a static NFC tag can be photographed or cloned. The existing defence is "looks right", which is exactly what a good fake achieves.
Whoever verifies has one phone and no patience. A tap that opens a page is the whole interaction — no app to install, no account to make.
Genuine, or not. A fresh AES-CMAC and a counter that only moves forward give a verdict with no judgement call in it.
Straight answers
A tag proves the tag. It cannot see the contents. Pair it with tamper-evident packaging so that opening the package destroys or invalidates the tag — otherwise a verified tap says nothing about what is in the box.
Genuine items carry genuine tags, so they verify. What you get is visibility — where and how often items are being checked — not a block. That is an analytics problem, not an authentication one.
NTAG 424 DNA tags cost meaningfully more than a printed QR code. On a low-value, high-volume item the maths often does not work. See where to buy tags for real per-tag prices before you plan a rollout.
Verification needs an NFC-capable device to read the tag. There is no offline visual check, and no way to verify a tag from a photograph of it — that is the same property that makes it hard to forge.
