Patented dual-frequency NFC + UHF. AES-128 unit identity.
A barcode carries data anyone can copy. The Aeroz chip carries a cryptographic identity bound to a single unit — phone-readable at the point of use, dock-readable at distance.
Different points in the supply chain need to read a unit in different ways. One chip answers both — without ever exposing two identities to clone.
A tap from any NFC phone confirms a single unit at the point of use — the dispenser counter, the inspection bench, the customer's hand.
A fixed or handheld UHF reader verifies units in bulk as they cross a dock — no line-of-sight tap, no opening the case.
NFC and UHF resolve to one AES-128 identity on the silicon. The unit is the same whether a phone or a dock reads it.
A 2D barcode can be photographed and reprinted in seconds — a cloned code scans as "valid." Encrypted silicon can't be copied with a camera. Here is how each carrier holds up.
| Capability | 2D barcode | NFC | UHF | Aeroz paired |
|---|---|---|---|---|
| Photograph & reprint | Cloned | Resists | Resists | Fails counterfeit |
| Tamper / refill | Invisible | Seal voids | Seal voids | Seal voids |
| Bulk dock verification | Line-of-sight | One at a time | At distance | UHF at distance |
| Regulated data carrier (GTIN / lot / expiry) | Native | Identity only | Identity only | Both, bound |
| Offline durability | Smudge / tear | Sealed IC | Sealed IC | Redundant |
We don't fight the barcode — regulators require it. We anchor it. The GS1 2D barcode carries the regulated data; the Aeroz chip carries cryptographic identity.
Clone the barcode and the chip check fails. Remove the chip and the tamper seal voids. The two carriers cover each other's weakness.
A chip intercepted in transit carries nothing to steal. Its cryptographic identity is assigned through the No-Encode workflow within a 72-hour window — not at the factory.
Until activation, there is no live key to clone. The unit becomes verifiable only once it enters your controlled custody.
Every scan, custody change, and approval is written once and never altered. There is no UPDATE, DELETE, or TRUNCATE for any role — the log only grows.
No UPDATE, DELETE, or TRUNCATE is exposed to any role. Events accumulate; nothing is rewritten after the fact.
Commission, ship, receive, and dispense are written as GS1 EPCIS 2.0 events — portable across compliant systems.
Unit-level custody maps to FDA Form 3911 format, so a traceback or notification is generated in seconds.
Each event is signed on write, so the integrity of every entry can be verified — not just the chain as a whole.
The tamper seal's state is recorded per unit the moment it changes, alongside who and where.
Every event for a single unit is retrievable from the log in under 60 seconds — defensible in front of an auditor.

A fixed-fee Aeroz audit produces a written gap analysis against your regulation, an EPCIS 2.0 readiness assessment of your stack, and a scoped plan to anchor every unit — with cost and timeline.
