The stamp is only as secure as the science behind it.
Tax stamp programmes protect billions in government revenue. Q-ID® makes them impossible to counterfeit and verifiable by any inspector, distributor, retailer and consumer, anywhere, in three seconds.
The problem
Tax stamp fraud costs governments hundreds of billions in lost excise revenue every year. Tobacco, alcohol, and fuel are the most targeted categories. But the problem isn't just the lost tax. It's the signal it sends, that the stamp itself can be beaten.
Every Q-ID® tax stamp carries a unique atomic fingerprint registered at point of print. It cannot be copied. It cannot be replicated with the same ink on a different press. And it cannot be reverse engineered from the data because no images are stored.
Anyone can verify in three seconds on a smartphone. No dedicated readers. No specialist training. A specialist Offline mode is also available exclusively for inspectors working without data connectivity.
Every scan is a data point. Location. Time. Device. Counterfeit hotspots surface in real time. Grey market diversion is detectable before it becomes a programme-level problem.
Verified by anyone, anywhere.
No dedicated readers. No specialist equipment. A smartphone verifies a Q-ID® tax stamp in three seconds.
Per-item integrity.
With batch-level serialisation, a suspect item casts doubt on the entire batch. With Q-ID®, every unit has its own registered identity. A single suspect item is isolated precisely for audit precision. The rest of the run is unaffected.
Registered at point of print.
Every Q-ID® is logged in the Proof of Print registry before it leaves the production line. A duplicate, even printed on the same press mismatches the registry immediately.
Real-time counterfeit intelligence.
Every scan generates location, time, and device data. Counterfeit clusters surface in real time. Enforcement teams know where to look before the problem scales.
GS1 compliant. Integrates with existing serialisation.
Slots into existing GS1aligned tax stamp regimes. One scan delivers authentication and serialisation data simultaneously.
Sovereign data residency.
Data can be hosted on-premises, in the cloud, or in a hybrid model by the government agency, by QB, or by an authorised partner. Full flexibility for data compliance requirements.

FAQ
Who's behind the science?
Quantum Base, founded out of Lancaster University in 2015 by Professor Rob Young. Listed on the London Stock Exchange (LON: QUBE), with 40+ patents and a decade of peer-reviewed research behind both products.
Are Q-ID®s really impossible to counterfeit?
Yes. Each Q-ID® is unique at the atomic level, a fingerprint created by quantum physics, not by design. Independent adversarial testing has confirmed it cannot be copied, and no equivalent smartphone-authenticated solution exists anywhere in the world.
How does Q-ID® compare to holograms, QR codes, and other anti-counterfeiting methods?
Holograms, QR codes, print uniqueness, taggants, and machine-learning approaches can all be photographed, studied, and eventually copied by someone with the right equipment. Q-ID®'s security isn't visual or informational, it's physical the identity exists at the atomic level, somewhere no counterfeiting operation can reach.
What's actually covered by the 40+ patents?
The core science: the method for creating atomic-level uniqueness in printed ink, and the algorithms that read and verify it from a standard smartphone. It's this combination — not just the ink, and not just the app — that the patent portfolio protects.
Who is using Q-ID® and Q-RAND®?
Security printers and government revenue agencies use Q-ID® worldwide; most engagements are confidential, which is typical in this industry, but over 2 billion Q-ID®s are live in market today. Q-RAND® serves sectors where true randomness matters: cryptography, blockchain, banking and fintech, defence, and simulations and gaming.
Can Q-ID®s be authenticated on any smartphone, and do we need an app?
50+ device models are supported as standard, running on almost every iOS and Android phone still supported by its manufacturer. No dedicated readers or specialist hardware needed. On iOS, App Clip technology authenticates without downloading anything at all; Android users go through the Q-ID® app or a branded app via the SDK.
Can Q-ID® be applied to any material or product shape?
Yes. It's been proven on logos, labels, boxes, plastic, metals, use-by codes, and polycarbonate for IDs and banknotes, if it can carry standard ink, it can carry a Q-ID®. The off-the-shelf format is 7×7 mm, with bespoke shapes and sizes available for specific applications.
Does Q-ID® replace our existing barcodes, serialisation, or track & trace systems?
No, it plugs into them. Q-ID® is GS1 compliant and works alongside the serialisation you already have one scan delivers both an authentication result and your existing track & trace data, so you're not running two systems side by side.
What does Q-ID® do that serialisation and barcodes don't already do?
A serialised barcode confirms a code exists, it doesn't confirm the product is genuine. Photocopy a barcode and it still scans as authentic. Q-ID® can't be photocopied into existence: no atoms, no signal, no result.
Can Q-ID® detect grey market or parallel imports?
Yes. Every Q-ID® is registered at point of print, and every scan is a data point, location, time, device. If a product shows up somewhere it shouldn't, that surfaces in real time, not months later in a report
Does adding Q-ID® mean switching suppliers or production lines?
No. Q-ID® integrates with your current printer's existing production line, litho or flexo, with no need to move your print contract or redesign packaging to add atomic-level authentication.
Is Q-ID® a physical product, a service, or both?
Both. Q-ID® is the quantum-active ink itself, plus the registration software, authentication app or SDK, and data platform that make it work, you're buying the full authentication system, not just ink.
Does Q-ID® work offline, and can we keep data on our own infrastructure?
Yes to both. An offline mode covers contexts like field inspection where connectivity can't be guaranteed, with data syncing once reconnected. Data residency is flexible, on-premises, cloud, or hybrid managed by you, Quantum Base, or an authorised partner, built for organisations with strict data sovereignty requirements.
Is the data collected through Q-ID® secure?
Yes. Authentication compares encrypted emission signatures, not stored images, so there's nothing to steal that could be reverse-engineered into a working Q-ID®. Scan data is yours, hosted according to your compliance requirements.
What's the first step if we want to explore Q-ID® for our organisation?
Get in touch and request a sample or a conversation. We'll talk through your specific risk, your product or system format, and your current setup, so you can see and test the technology yourself before making any commitment.
