Ownership travels with the object.
Most systems change ownership by editing a record in a database. With Rethentic, a transfer happens securely in the Rethentic app and moves ownership through the object itself, so the new owner inherits proof they can rely on. Reading an item's product passport still takes no app at all.
When you sell or gift the item, its verified identity and history go with it. You can't pass along a certificate or record without the object itself.
Anyone can open the item's product passport on any phone with no app, and whoever holds the item can confirm the chip itself in the Rethentic app. There's no paperwork or database to take on faith.
Every change of hands stays bound to the object, so provenance and ownership survive resale after resale.
A blockchain can prove a record changed hands. It cannot look at your watch. Someone outside the chain has to promise the record and the object are still the same thing, and that promise is where these systems break. Rethentic asks the object instead. The chip advances its own counter on every genuine transfer, so a claimed history that disagrees with the chip fails on the next tap. Verification is near instant too, with no gas or transaction fees.
Why it holds: Ownership and provenance stay bound to the object through every sale, giving you a history that can't be quietly reassigned or handed off without the item itself. And because the chip carries its own key and its own count of genuine transfers, an item keeps proving it is authentic and that its history has not been padded, with or without us.
OUR PROTOCOL
THE LINK PROVES NOTHING
Our competitors build on NTAG chips where the URL carries the proof. Tapping hands the phone a link, so the phone learns where to ask and whoever programmed the tag chose who answers. The better ones sign every tap, which defeats a plain copy and still leaves the proof traveling in a link that anyone within range can lift, while the chip only counts taps. Nothing about who owns it is ever written to it.
A Rethentic link carries no proof at all. It opens a public product passport, the kind the EU Digital Product Passport asks for, and that page states plainly what it does and does not establish. Authenticity is a separate cryptographic exchange with the chip, and a genuine interaction changes the chip itself, so the proof lives in the object and moves with it. A copy does not survive the next genuine tap. Moving ownership takes the chip and the Rethentic app together, which is the part no parallel site can mint.
That some server answered yes. Anyone can run a server, and a consumer cannot tell a real register from a convincing one, because both arrive as a web page after a tap.
That this specific chip answered a challenge only it could answer, and that the custody written to the ledger is what actually happened to the object in your hand. Our own server earns no more benefit of the doubt: every entry is anchored to an interaction the chip itself advanced, so a history nobody lived cannot be made to match the object you are holding.
Rather than ask you to take our word for it, we forged a luxury passport ourselves. Fraudex is a maison we invented, with a tag anyone could write, and a page that says Verified Authentic without checking a thing.
See the forgeryYOUR SUPPLIER SHOULD NOT DECIDE YOUR FUTURE
Many secure NFC authentication systems depend on a single family of chips: NXP’s NTAG 424 DNA. Their security is built around the capabilities of that particular hardware.
One decision in a roadmap meeting, made by people who may never have heard of your company, could discontinue the chip at the heart of your business. Suddenly you are facing expensive redesigns, complicated migrations, and years of unexpected engineering work.
Rethentic is differentOur technology is not tied to NXP, NTAG, or any single manufacturer. The protocol already runs across three different chip families with different command sets and file layouts, which is the same abstraction a change of manufacturer needs.
Rather than designing our system around a particular chip, we define the security requirements and let compatible hardware fulfill them. That gives us the freedom to choose the best device for each product, switch manufacturers, and adopt new technology as it arrives.
When better hardware arrives, new products can adopt it while existing products continue working. Different chips, different manufacturers, different generations, all operating within one system, with the same security rules and ownership history.
The trust lives in the method, not the part.
NTAG 424 DNA, DESFire EV2 and EV3, DESFire Light, and whatever ships next.
Tags that hold a key, not just an ID. Read at range across a warehouse.
Goods that pair instead of tapping, with a secure chip behind the radio.
Connected products with a secure chip on board, proving which unit they are.
Built to last: Your products can last generations. Your authentication system should, too.
SECURITY WITHOUT THE PHYSICAL ITEM ISN'T SECURE
With Rethentic, ownership cannot move without the object. QR codes and serial numbers can be photographed and reprinted. Certificates and app-based registries live beside the object, so the record survives even when the item does not. Rethentic bonds a cryptographic chip to the item itself and makes every transfer an exchange that chip has to complete: remove it and the proof breaks, copy the data and the next genuine tap exposes it. The ledger entry and the object are the same record.
