The problem DPT solves: proof that floats free of the product
Certificates, holograms, and printed labels can all be copied, reused, or swapped, because the proof and the physical item travel separately. A certificate proves that a genuine item exists somewhere. It does not prove that the item in your hand is that one.
That gap is exactly where counterfeiting, refilling, and swapping happen. A genuine bottle is emptied and refilled. A graded collectible is moved into a different holder. A premium cut, jar, or handbag is paired with paperwork that belongs to another unit. Spirits, collectibles, food, and luxury goods all share the same structural weakness: the document and the object can be separated.
How Digital Provenance Technology works
DPT has three parts working together.
1. A tamper-evident NFC seal
An NXP NTAG 424 DNA chip — standard or TagTamper — is applied to the individual item. Tapping it with a phone opens that item's record. If the seal is interfered with, the tamper is visible and recorded.
2. A provenance registry
The registry stores the item's record — origin, attestations, and chain-of-custody events — and updates as the item changes hands, so the history grows rather than being rewritten.
3. A verification experience
Anyone can scan or tap to see who verified what, and when — no account, no app, and no special hardware.
DPT references existing authorities — registries, laboratories, and certification bodies — rather than replacing them. Their findings become attestations attached to the item's record.
Attestation levels: what "verified" actually means
Not all claims carry the same weight, and good provenance is transparent about which is which. A tiered model makes the difference legible:
- Registry record (owner-attested) — the item exists in the registry with details supplied by its owner.
- Sealed (tamper-evident from date applied) — an owner or dealer has applied a tamper-evident seal, so the item's state is verifiable from that date forward.
- Event-verified — an authorised party inspected the item before sealing it. This is the highest trust signal.
The point is not to flatten everything into a single "verified" badge. It is to show the buyer exactly who verified what, so trust is earned by evidence rather than asserted.
Authentication tiers: NFC, QR, and visual
Verification is layered so it works across a range of products and buyer situations. An NFC tap is the primary and strongest signal: the chip produces a fresh cryptographic response on every tap, which cannot be photographed or copied.
A QR code serves as the widely accessible fallback for any camera-equipped phone, and visual or 2D markers provide a further tier where a chip or code is impractical. Read more about the primary tier in NFC product authentication.
Where DPT is used
DPT is category-agnostic infrastructure with vertical applications: one provenance rail, many verticals. Cerfinity operates it under purpose-built brands —
- Spirits — SpiritSeal™: sealed-bottle and opening verification for premium spirits.
- Graded collectibles — SlabProof™: unit-level provenance for graded cards and comics.
- Premium meat — TrulyMarbled: binds each cut to its individual animal's registry record.
- Retail engagement — Scan and Groove: turns an everyday tap or scan into a branded experience.

DPT vs. blockchain "authentication"
DPT is registry-anchored and outcome-focused. The goal is checkable proof bound to a physical item, not the adoption of a particular database technology. A provenance registry may be backed by a ledger for tamper-resistance, but that is an implementation detail: the buyer experience is a simple tap-to-verify, with no wallet, no token, and no technical knowledge required.
Authentication products marketed primarily on their underlying ledger foreground the technology instead of the verification outcome. Both approaches can be sound. The distinction worth understanding is what the buyer is actually asked to do, and whether the proof is bound to the individual physical item at all.
Frequently asked questions
- What is Digital Provenance Technology?
- Digital Provenance Technology (DPT) is a system that binds a single physical item to a verifiable digital record of its origin and history. The record is tied to the individual unit rather than to a product line, so anyone holding the item can confirm that this specific one is authentic, where it came from, and that it has not been tampered with.
- How is DPT different from a certificate or hologram?
- A certificate or hologram is a separate artefact that can be copied, reused, or moved to another unit. With DPT the record is bound to the individual item through a tamper-evident seal, so the proof travels with the product itself and any interference with the seal is visible.
- Do I need an app or a crypto wallet to verify an item?
- No. You tap or scan the seal with an ordinary smartphone and the item's record opens in a browser. There is no app to install, no account to create, and no wallet, token, or crypto knowledge required.
- Does DPT guarantee product quality or safety?
- No. Digital Provenance Technology attests to authenticity, origin, and chain of custody only. It makes no quality, safety, or health claims about the product itself.
