We have used the phrase connected product for years because it gives people a quick way into the conversation. A physical object can open a digital experience. That idea is understandable, useful, and already happening across many industries.
It is also incomplete.
A connection does not tell us whether an object is individually known, whether a claim is credible, who governs the destination, what should happen when information changes, or how the relationship survives after a campaign ends. It describes a door, but not the system of responsibility behind it.
That gap is why we published The Physical Identity Manifesto.
Physical identity is larger than NFC
NFC is one way a person can interact with a physical object. QR codes, serial numbers, computer vision, embedded electronics, and other methods can create similar bridges. We work with connected physical systems, but we do not believe the interaction method is the whole product.
The larger question is what should persist around the object: its identity, instructions, origin, lifecycle, trust signals, cultural meaning, service context, or relationship with the person who owns or encounters it.
Physical identity is our name for that larger system. It joins the object to appropriate digital context, makes authority and permissions explicit, and lets the experience evolve without discarding the object’s continuity.
The distinction also keeps our claims honest. A tap can create a connection. It does not automatically authenticate the object. A serial can distinguish one unit from another. It does not automatically prove provenance. A verification system can evaluate defined evidence. It should never imply certainty beyond what it actually checked.
Instruction, trust, lifecycle, and governance belong together
The same design problem appears in very different rooms.
A learner needs current instruction while standing beside a machine. A customer needs care information after the package is gone. A technician needs the right service record in front of an installed component. A museum visitor wants a deeper interpretation than a label can hold. A collector wants to understand an edition and the evidence around it.
In each case, the physical object is the point where context becomes useful.
But usefulness alone is not enough. Someone must be responsible for the information. The system needs rules for updates, access, privacy, accessibility, expiration, transfer, and failure. If a digital identity is meant to persist, stewardship is part of the product.
That is why the manifesto treats instruction, trust, lifecycle, and governance as one design problem rather than separate features.
Two bodies of work shaped the publication
Amy’s work in instructional design, learning experience, customer and workforce education, the last mile of learning, and Persistent Retail keeps returning to one question: can useful information arrive when a person is ready to act on it?
Andrea’s work in product vision, manufacturing, physical-to-digital systems, authentication, platform design, and connected experiences keeps returning to another: can the object remain a durable, governed point of access throughout its life?
Those questions meet in physical identity.
Neither perspective is secondary. Learning without trustworthy context can become noise. Identity without a meaningful experience can become infrastructure in search of a reason to exist. The framework needs both.
Why publish the thinking openly?
We are building a company, but this publication is not a product brochure. Organizations need language for examining the category before they choose an implementation.
We also know that State of Stick did not invent every concept in this field. NFC, QR, digital twins, product passports, provenance systems, authentication, lifecycle records, and connected products have histories much larger than our company. We are defining our own physical-first framework for how these ideas can work together, and contributing it to a broader emerging conversation.
Open publication makes the framework easier to test. Manufacturers can tell us where it fails in long service lives. Educators can challenge whether learning is truly contextual. Privacy and security practitioners can examine its boundaries. Museums and artists can ask whether identity protects or flattens meaning. Policymakers and standards contributors can identify where shared language would help.
How to engage
The complete Physical Identity Manifesto includes the working definition, the distinction between shared, serialized, and verified identity, nine principles, an object-to-lifecycle model, and focused industry field notes.
We welcome conversations with research partners, manufacturers, educators, technology partners, pilot customers, standards and policy contributors, and investors aligned with responsible physical-to-digital infrastructure.
If the category touches a real problem in your work, explore the industry applications or start a conversation.
Physical first. Digital second life.
